Fragilaria gracilis The valve shown in the original picture of Østrup (1910, Tab V, Fig. 117) has a length of 43 and a width of 2.1 µm, with 25 striae per 10 µm. The microphotographs from the lectotype slide, coll. Østrup 1342, given in Krammer and Lange-Bertalot (1991) and Tuji (2007), show lengths of 28-54 µm, widths of 2–2.7 µm, and 18–24 striae per 10 µm. Tuji (2007) describes the striae as “being parallel throughout”, with SEM pictures showing opposite striae with some irregular parts where striae are alternate. These alternate parts are however not common, even if Lange-Bertalot and Ulrich (2014) define the striae as “opposite or alternating”. Note that the term “parallel” refers to the orientation of the striae to each other, while the terms “alternate/opposite” refers to whether the striae on either side of the sternum F. gracilis has been isolated and cultured to clones several times, and the Thonon Culture Collection (TCC) is hosting living strains.

These are contabulate, the first whorl somewhat eroded, the two following whorls bicarinate, the penultimate and body whorl more or less tricarinate. The body whorl is sculptured with 24 spaced spiral striae with microscopic vertical striae in the interstices. The fourth, sixth and eighth striae below the suture on the body whorl are larger than the others and three or four striae near the umbilicus are closer together. The umbilicus is of moderate size.

In human neuroanatomy, the longitudinal striae (also striae lancisi or nerves of Lancisi) are two bundles of fibres embedded in the indusium griseum running along the corpus callosum of the brain. They were originally described by Italian physician, epidemiologist and anatomist Giovanni Maria Lancisi. The striae are categorized as medial longitudinal stria and lateral longitudinal stria; the area between the striae is a useful neurosurgical mark of the middle of the corpus callosum. After the indisium griseum curves along the rostrum of the corpus callosum the combined striae continue toward the amygdala as part of the diagonal band of Broca.
|
|
It has about 24 spiral threadlets. It is crowded with fine sinuous oblique accremental striae. The periphery is acutely angular, with a projecting rounded carina, spirally closely engraved on its upper surface andaxially crossed by rounded striae. These are much more distant than the accremental striae, provided at somewhat irregular intervals with 16 rounded invalid tubercles.
|
|
In the vicinity, the medullary striae may also be seen.
|
|
The length of the shell varies between 1 mm and 2.5 mm. It has a trochiform shell. The spire contains 3½ rather convex whorls. They are finely decusate by elevated longitudinal striae and close striae.

The ratio of elytral length to greatest elytral width 1.45–2.85. Ratio of elytral length to pronotal length 1.75–5.75. Elytra apunctate, irregularly punctate, or with 5 or fewer distinct puncture rows or striae, or with more than 5 distinct puncture rows, or with more than 5 distinct impressed striae; without scutellary striolae. Number elytral puncture rows or striae 9.
|
|
One or two spiral elevated striae may be observed on part of the upper whorls. Moreover the whole shell is covered with fine growth striae, which form a large sinus above near the suture and are protracted below near the keel, following the direction of the riblets. The base of the shell is rather smooth, but sculptured by similar striae as on the upper part, being partly riblike. The whole base is covered with spiral striae, most conspicuous towards the umbilicus and keel, leaving a smoother median space.
|
|
The size of the shell varies between 26.1 mm and 82 mm. The whorls of the spire are striate, maculate with chestnut. The body whorl is shows beaded striae below. Sometimes the granular striae cover the entire surface.
|
|
The outline is long and the polished surface show s no spiral striae except on the penultimate and beginning of the body whorl, where fine, scarcely impressed, close spiral lines can be seen under a strong lens. A few separated impressed striae extend along the columellar margin of the base. The columellar margin is slightly bowed or concave. The upper surface has subregular radiating striae.
|
|
The sculpture is somewhat coarse. Only visible under a lens, one can observe between the rows of granules, a few fine, spiral, elevated striae, 1 to 3 in each interstice of the body whorl, crossed by oblique, slightly lamellose striae. On the base of the shell one can observe also one distinct, and often 1 or 2 very small intermediate, lirae, and also less crowded oblique striae.
|
|
In the latter case mainly two spirals are stronger. Moreover, there are extremely fine spiral striae and rather conspicuous growth-striae. The aperture is elongated and angular above. The peristome is thin, with a wide sinus above, then protracted.
|
|
The striae are decussated by slightly elevated spiral striae, with smaller ones between them. Its color is deep opaque black, obliquely girdled with white. The spire is lateral and slightly prominent. The four whorls are separated by impressed sutures.
|
|
Typical character of this genus: the spiral sculpture consists of fine, incised striae.
|
|
Margarinotus brunneus can reach a length of about . Body is shiny black in colour. These beetles are characterized by the presence on the pronotum of complete marginal stria, by two lateral pronotal striae and basal fragments of the 5th dorsal striae.
|
|
This body whorl is nearly smooth, except for most tender spiral and radiating striae, only visible under magnification, and a few remote deeper striae near the suture, being the continuation of the beads. It is strongly depressed, more convex above than below, with a blunt angle, but no keel. The umbilicus is funnel-shaped, moderately wide and pervious. Its walls are smooth, with only a few growth striae.
|
|
These folds are crossed by very fine and very numerous transverse striae, colored with articulated, elongated, brown and whitish spots. The striae of the base are more strongly prominent. The whitish aperture is ovate. The outer lip is thick and denticulated internally.
|
|
The elytra have a glabrous surface with fine striae and one spine on each apex.
|
|
The hindwings are semihyaline whitish grey, while the margins, veins and some striae are brown.
|
|
Paratorchus differs from Holotrochus only by having reduced eyes and elytra with indistinct sutural striae.
|
|
Its upper surface is encircled by 4 coarse, somewhat beaded lirae, the upper two contiguous, the third separated by wide intervals above and below it, the fourth peripheral, usually formed of two ridges close together. The interstices bear numerous fine spiral striae and sharp microscopic incremental striae. The convex base is concentrically sculptured with numerous (6 to 9) smooth striae, in the intervals between which very numerous microscopic striulae revolve. The rounded aperture is oblique.
|
|
The narrow umbilicus is profound. The slightly elevated, rather narrow, transverse striae are crowded, blunt, and very unequal above, on the base rather regular and elevated. The striae number 4 on the penultimate whorl, about 6 above the periphery of the body whorl, with here and there an intermediate smaller one, and upon the base 10 less elevated ones. The interstices look pitted on account of the elevated incremental striae that cross them.

|
Tooth of a Paranthropus robustus with striae of Retzius visible on the left side The striae of Retzius are incremental growth lines or bands seen in tooth enamel. They represent the incremental pattern of enamel, the successive apposition of different layers of enamel during crown formation.
|
|
Transverse striae, pretty fine and numerous, are observed between each of the rows of the spines. The white aperture is semilunar. The outer lip is thick and furnished internally with fine striae. The columella is nearly straight, covered by the inner lip which forms a callosity.
|
|
Shell of elongate oval shape, with relatively high and pointed spire and a large body whorl. The shell is smooth and shiny except for the upper (= posterior) half of the body whorl which carries dense longitudinal grooves, or striae (hence the name semistriata). These striae are a distinctive character that separates O. semistriata from all other Olivellidae; however, the striae do not begin to form before the animal exceeds 10 mm shell length. The suture is open.
|
|
The costal striae is narrow, inconsecutive and usually indistinct, while the dorsal striae is broad and clear, the latter two striae inconsecutive. The dorsum has a broad white band along the basal , a narrow silvery-white fascia bearing a bluish metallic reflection from the costal to the dorsum, arched outward medially. The distal is ochreous, with a central black dot near the fascia at , with a broad white band along the costa and dorsum. The hindwings are pale grey.
|
|
The forewings are pale cream with pale brown striae. The hindwings are white with grey-brown mottling.
|
|
The most common symptoms seen in male patients are purple striae, muscle atrophy, osteoporosis, and kidney stones.
|
|
Genetic factors such as genealogy and race also seem to be predictive in the appearance of striae.
|
|
The spiral striae of the surface are fine, close, and often disposed in pairs. They are decussated by very close fine radiating striae. The spire is low. It is inside silvery and smooth except for fine spiral folds in the nacre, which has light green and red reflections.
|
|
The current literature suggest that in the general population of the US, there is a 50%-90% prevalence of striae associated with pregnancy, partly as a result of the normal hormonal changes of pregnancy and partly due to stretching of skin fibers. Many women experience striae gravidarum during their first pregnancy. Nearly 45% percent of women develop striae gravidarum before 24 weeks of gestation. Many women who develop lesions during the first pregnancy do not develop them during later pregnancies.
|
|
Each elytron shows eight deep and distinctly punctured striae. This click beetle is a predator on scarab larvae.
|
|
These riblike striae are less conspicuous on the body whorl. The lower part of each whorl has the appearance of a broad margin, slightly concave above, separated from the upper part of each whorl, by a kind of spiral rib, which is slightly crenulated. This marginal part is sculptured by rather conspicuous spiral and stronger, oblique, but nearly straight, riblike radiating striae, which on the upper part make the keel slightly crenulate (on the largest specimen the keel is smooth, on account of the less conspicuous sculpture). The basal part of body whorl is convex, with a few more or less conspicuous spiral striae around the umbilicus, and faint, strongly curved, radiating striae.
|
|
The length of the shell varies between 5 mm and 12 mm. (Original description) The ovate shell has a rather short spire. The whorls are rounded at the upper part, longitudinally very closely finely ribbed, decussated with transverse striae. The ribs, being decussated with striae, have a slightly granular appearance.
|
|
The length of the shell attains 60 mm, The oblong, conical shell is rather thin. It is of a reddish-brown color, covered transversely with striae and ridges, with some slightly apparent longitudinal striae. The transverse ridges are raised and very prominent. The spire is elongated and contains seven whorls.
|
|
The surface is smooth, except for very light growth striae and narrow impressed spiral lines. There are a few narrow raised striae between the row of holes and the columellar margin. The inner surface is silvery and iridescent. The columellar plate is flat, wide above, gradually becoming narrower toward its base.
|
|
Midway between these are smaller ones, and there are still finer spiral striae occupying the interstices. The whole is decussated by fine striae of growth. There is an angle or carina midway between the periphery and suture of the body whorl, which angulates the spire whorls. The short spire is conic.
|
|
The columella is curved and slightly reflected at the upper part. The interior of aperture is smooth and nacreous. The operculum is many-whorled, outer 2 whorls broad;. The whorlsare sculptured by radiating and concentric striae, causing a latticed appearance, radiating striae stronger on the distal half of each whorl.
|
|
VI; Philadelphia, Academy of Natural Sciences It is also characterized by small, wavy spiral striae that are little protruding.
|
|
The length of the shell varies between 15 mm and 25 mm. The solid shell has a conical shape with nearly straight outlines and is false- umbilicate. The sculpture of the upper surface consists of 5 series to each whorl of rounded bead-like granules, between which are visible numerous very minute spiral striae, in the interstices of which oblique incremental striae are prominently shown under a lens. The base of the shell is concentrically striate with unequal striae that disappear toward the outer edge.
|
|
Some have suggested that relaxin and estrogen combined with higher levels of cortisol during pregnancy can cause an accumulation of mucopolysaccharides, which increases water absorption of connective tissue, making it prime for tearing under mechanical stress. There also seems to be an association between higher body mass indices and in women with bigger babies and the incidence and severity of striae. Also, younger women seem to be at higher risk of developing striae during pregnancy. The prevalence and severity of striae gravidarum varies among populations.
|
|
Their surface is deeply chequered by longitudinal folds, crossed by numerous striae. The aperture is moderate, white and ovate. The outer lip is thick, ornamented within with seven or eight striae, of which those of the middle are generally the largest. The columella is slightly arcuated, covered with a thin, brilliant plate.
|
|
Pronotum is transverse shaped, posteriorly sharply narrowed, wrinkled and punctured. Elytra are flattened with clearly visible punctures in the striae.
|
|
The forewings are pale whitish with brown striae in distal part. The hindwings are whitish with pale grey-brown mottling.
|
|
The shell is very different from those of the other nautili in being much more deeply indented with circular striae.
|
|
They are marked at their upper part by a marginated suture, and two slightly apparent striae towards the base. The body whorl is shorter than the spire, marked at its base with regular, transverse striae or ridges. The oval aperture is oblong, smooth and white. The outer lip is thin and sharp, slightly plaited internally.
|
|
The shell is very fine and contains very close transverse striae, crossed by very fine and slightly apparent longitudinal striae. The spire is elongated, pointed and contains eight convex whorls to the spire. These are traversed sometimes by slightly prominent longitudinal folds. The aperture is very effuse, dilated outwardly and widely emarginated at its base.
|
|
The size of an adult shell varies between 35 mm and 95 mm. The heavy shell is closely striated, the striae minutely granular. The spire is short but acuminate. The color of the shell is yellowish white, clouded irregularly with orange-brown or light purple-brown blotches, with numerous chestnut spots on the striae.
|
|
The last 2½ whorls are smooth, with only very faint, traces of growth-striae and spiral striae, but with a row of oval beads, just below the conspicuous suture. The periphery is rounded. The base of the shell is nearly flat, impressed near the centre, which is more or less filled by a thick callus, which is white, with radiating striae on its external margin, granular near the columellar margin, and is ornamented there, with 4 or 5 granules. The base of the shell round the callus, is likewise provided with radiating grooves.
|
|
The striae between the infrasutural and peripheral rib turn of the left, while those between the peripheral and the next rib (or in the upper whorls between the rib in the middle and the base) turn to the right. The same alternate order is to a great extent observable as to the direction of the striae on the base of the body whorl. These striae are crossed by fine close- set spiral lines, producing a reticulated appearance. All the whorls are similarly sculptured, except the top whorl or apex, which is smooth.
|
|
The species name refers to the three parallel striae of the forewings.Acta Zoologica Academiae Scientiarum Hungaricae. (2004). 50 (4): 337–351.
|
|
The Fragilaria have a pseudoraphe, rather than a true longitudinal groove in their valves. The valves are symmetrical with transverse striae.
|
|
There are blackish lines, forming indistinct shades and striae, as well as blackish spots on the costa and an interrupted blackish inner line, a dark spot at the end of the cell and an outer irregular dark line, connected with the submarginal irregular shadings. The hindwings are brown with irregular darker transverse striae on the outer half.

|
The other whorls are somewhat convex, except; the last but one. Their surface is ornamented with eleven or twelve distant, prominent, rounded, longitudinal folds, intersected transversely by fine compact striae. The violet gray aperture is ovate and slightly oblique. The outer lip is furnished interiorly with numerous striae which are continued even to the depth of the cavity.
|
|
Upon the surface of this shell, are seen equal, raised striae. The white aperture is subrotund, narrowed at the upper part and dilated inferiorly. The thin outer lip is crenulated upon the edge, and marked interiorly with very prominent transverse striae . The columella is arcuated and covered by the inner lip, which is obliterated, flattened and corrugated above.
|
|
The interstices are under the lens finely striated, the striae running parallel to the ridges. These fine striae cause interference with the light, giving rise to iridescence when viewed obliquely. The aperture is circular and continuous. The lip is broadly margined, the margin being sculptured in a manner similar to the other portion of the body whorl.
|
|
The striae of Retzius often extends from the Dental-enamel junction to the outer surface, ending in shallow pits known as perikymata.

It is intersected by numerous transverse striae. The upper extremity of the fold is sometimes separated by a stria which divides them superficially. The white aperture is ovate, terminated above by an emargination of the outer lip, and by a transverse ridge of the inner lip. The outer lip is thin, slightly denticulated at the base, furnished with numerous striae; internally.
|
|
The spaces between are occupied by intervening smaller spirals and very close, fine, microscopic spiral striae, decussated by finer radiating striae of increment. The upper whorls show low, radiating, scarcely visible folds. The base is nearly smooth, having only fine separated spiral threads with flat interspaces. All sculpture becomes obsolete in the white crescent except the fine, very oblique growth lines.

|
It is very solid, obtusely ribbed with fine spiral striae. The outer lip is extremely thickened. The inner lip is simple. The aperture is ovate.
|
|
The white marks on the ribs is continued as a white band on the smooth part, but it is superficial and not deeply seated. The shell shows spiral striae over whole whorl, 5–6 on the sulcus, 14-15 (or more) below (visible in worn specimens only between the ribs) and c. 15 stronger and more widely spaced striae on base. The aperture is oblong-ovate.
|
|
The body whorl shows five longitudinal ribs, squarely rhomboidal, angulated near the suture, and carinated at the periphery, the ribs having projecting points here, and the carina being curved between them. The body whorl is excavately contracted below. Scarcely visible sublenticular longitudinal striae in upper part; rather less obsolete spiral striae. These are more valid below the carina, where seven can be counted on the ventral aspect.
|
|
The neonatal line is a particular band of incremental growth lines seen in histologic sections of both enamel and dentine of primary and permanent teeth. It is made partly after birth. It belongs to a series of a growth lines in tooth enamel known as the Striae of Retzius. The neonatal line is darker and larger than the rest of the striae of Retzius.
|
|
Forewing apical ocellus large as on upperside, but with an additional thin reddish outer ring. Forewing termen margin covered with a thin scattering of white scales tapering towards tornus. Hindwing white scales forming prominent small lines (striae) with slight violet tones covering the whole wing apart from a narrow area around the tornal ocelli. Striae become darker towards the costa and apex giving a fading effect.
|
|
The whole surface of the shell is covered with radial striae, crossing the lirae and giving them a beaded appearance, especially near the suture and the umbilicus, where they form regular folds. The umbilicus is pervious and funnel-shaped. Its wall contains flat spiral lirae, crossed by much more crowded, radial, elevated striae, separated by a conspicuous angle from the basal surface. The aperture is subquadrate.
|
|
The sculpture consists of a keel at some distance from the suture, enclosing a concave zone, and another keel near the periphery. Between these keels runs a row of elongated, slightly oblique tubercles. Moreover the whole shell is covered with fine spiral striae and still finer growth-striae. The aperture is very oblique, its upper margin concave near the body whorl, then strongly convex.
|
|
The fusiform shell consists of ten whorls. The angular whorls are crossed by delicate, spiral striae and longitudinal obtuse ribs. The whorls are tuberculated in the middle, the tubercles developing from more or less indistinct oblique folds or ribs, everywhere closely encircled by striae. The dark fulvescent shell shows a banded white zone that passes over the nodules upon the angle in the center of each whorl.
|
|
Stretch marks (technically called striae) are also a form of scarring. These are caused when the skin is stretched rapidly (for instance during pregnancy, significant weight gain, or adolescent growth spurts), or when skin is put under tension during the healing process, (usually near joints). This type of scar usually improves in appearance after a few years. Elevated corticosteroid levels are implicated in striae development.
|
|
Striae gravidarum (pregnancy-related stretch marks) occur in 50% to 90% of women, and are caused both by the skin stretching and by the effects of hormonal changes on fibers in the skin. They are more common in younger women, women of color, women having larger babies and women who are overweight or obese, and they sometimes run in families. Stretch marks generally begin as red or purple stripes (striae rubra), fading to pale or flesh-color (striae alba) after pregnancy that will generally be permanent. They appear most commonly on the abdomen, breasts, buttocks, thighs, and arms, and may cause itching and discomfort.
|
|
Below this liration the shell is concave towards the basal or peripheral liration, which in the upper whorls, runs just in the suture and in the last one borders the basal surface. These lirations are slightly spinous. Distinct undulating plications run from one to the other of the lower lirae, with the convex side towards the aperture On the upper part they are directed in an opposite way, being less distinct about halfway the interspace between the upper and median liration. Moreover, the whole shell is covered with much weaker striae, having the character of growth striae and traces of more remote spiral striae.
|
|
There are three pairs of white striae from both the costal and dorsal , and extending obliquely outward to the middle and the end of the cell, as well as outside of the cell. The dorsal striae are broader and clearer than the costal striae and the basal of the dorsum with a broad white band. There is a narrow silvery-white fascia with a metallic reflection from the costal to the dorsum, arched outward medially. The distal is ochre brown, with a central black dot edged by a short white streak or a dot near the costa, with a white band along the dorsum.
|
|
Pregnancy stretch marks, also known as striae gravidarum, are a specific form of scarring of the skin of the abdominal area due to rapid expansion of the uterus as well as sudden weight gain during pregnancy. About 90% of women are affected. A number of additional factors appear to promote the appearance of stretchmarks: one study of 324 women, done just after they had given birth, demonstrated that low maternal age, high body mass index, weight gain over 15 kg (33 pounds) and higher neonatal birth weight were independently correlated with the occurrence of striae. Teenagers were found to be at the highest risk of developing severe striae.
|
|
The suture is distinct and deeply impressed. The longitudinal sculpture shows about 14 elevated ribs. The spiral sculpture consists of many striae, mostly below the carina.
|

In another sermon in the same period, the Geniscus appears in the company of witches (striae) and other entities in whom "rustics" believe:Filotas, Pagan Survivals, p. 79.
|
|
Occasional growth striae cross the shell obliquely. The aperture is pyriform. The columella is excavate. The outer lip is grooved within and bevelled to a sharp edge.
|
|
The whole surface is microscopically spirally striate. The striae are coarser on the base. The 8 to 9 whorls are nearly flat. The upper whorls are pink.
|
|
It should also be stressed that all the members of Astereae had amphistomatic bifacial leaves with striated cuticles, while striae were absent in all members of Gnaphalieae.
|
|
Outer lip is crenulate, with several strong lirae into the aperture. The ovate, oblong shell is rough, and slightly turreted. Its entire surface is apparently armed with small spires. The spire is pointed and composed of nine or ten rather convex whorls, furnished with longitudinal folds or ribs, somewhat distant, and formed by the elevations of transverse striae, which are also cut transversely by other striae elevated and resembling sharp scales.
|
|
The base has very numerous spiral striae which are crossed by numerous radial growth lines. The protoconch and primary whorls are white and the main body whorls are a pale buff to white color with an iridescent coppery metallic sheen. Occasionally the teleoconch (body whorls) are overlaid with pale orange or pink axial flammules. The selenizone has no distinct spiral sculpture however it has numerous fine curved growth striae.
|

They are rather convex and slightly angular by the projection of one of the numerous lirae. These number about 6 on the penultimate whorl, and 7 on the upper part of the body whorl, besides several intermediate, elevated striae, which become very numerous towards the aperture. The body whorl is angular at the periphery. Its convex base has numerous, crowded, elevated striae (partly wanting in a few specimens).
|
|
The 10–25 × 6–12 mm shell is slender with the whorls often not very convex and nearly always with flat sutures. It is brown, irregularly striated (surface ornamented with strong spiral striae which cross-cut the radial growth striae – this can lead to the development of quadrate plates) and the apertural height is about 50% of the shell height. The umbilicus is closed.Species summary for Stagnicola fuscus.
|
|
Often the folds upon the body whorl disappear partially upon the edge of the outer lip, and this whorl presents at its base a few striae which intersect the folds crosswise, and thus form granulations. The whitish aperture is subrotund and a little narrowed above. The thick outer lip is accompanied by a slightly prominent external varix. The internal part of the lip is marked with numerous fine striae.
|
|
The shell contains longitudinally close, thick ribs. The interstices show longitudinal striae. The aperture is circular and white on the inside. The conspicuously thickened peristome is five-angled.

In crossing the ribs, they produce still 2 fainter tubercles on the lirae of penultimate whorl. Numerous ones on the body whorl, but not on the siphonal canal, where the ribs disappear. Moreover the shell is crossed by very fine growth-striae, more conspicuous in excavation and fine spiral striae, of which about 2 in excavation. The aperture is oval, angular above, ending in a short, wide siphonala canal below, slightly directed to the left.
|
|
The length of the shell varies between 19 mm and 35 mm. The ovate shell is thick, solid and bi- conical. It is whitish, covered with a reddish epidermis. It shows nine or ten longitudinal folds, more strongly marked upon the body whorl, rarely prolonged as far as the base, and regularly divided into tubercles by more prominent transverse striae, the interstices of which are furnished with other much finer and very approximate striae.
|
|
The periphery is lighter, often spotted. The base of the shell shows a paler vermiculate and articulated pattern. The surface is closely and evenly sculptured with spiral striae throughout, with inconspicuous rather spaced oblique impressed lines, and between them very faint, close growth-striae which slightly crenulate the spirals. The five whorls are very convex, rather flattened below the sutures, and produce a blunt median angle on the whorls of the spire.
|
|
The darker striae (crosslines) are indistinct and obtusely angulated. The edges of a vague geniculate median band are marked faintly darker, especially as two dark costal spots which form the corners of an equilateral triangle with the discal spot. The forewing fringes are chequered to not chequered. The hindwings are fuscous with only very faint striae and fasciae; even less conspicuously patterned than the forewings but with a clear dark fuscous, shortly linear discal mark.
|
|
The surface is conspicuously grooved, those above the periphery having 3 or 4 smaller striae intervening. Beneath it is somewhat imbricated upwards, and barred in the intervals by the lines of growth, which do not pass over the ridges. One-half the breadth of the base adjoining the columella is plain, without striae, and banded by a raised and milk-white line. There is a slight reflection of the columella against a minute perforation.

Under the microscope a system of much finer regular striae is seen to cover the whole surface. Spirals — there are many fine, irregular, and unequal rounded striae, which faintly appear on the surface, but are distinct on the columella and front of the shell. Besides these, there are fine microscopic smooth scratches. The colour of the shell is white, with a faint tinge of yellow, horny, translucent, with a smooth and shining, but hardly glossy, surface.
|
|
The intermediate space on the base is marked with eight to ten impressed spiral striae. The interstices of the spirals are crossed by longitudinals, which are regular, fine, hair-like, but distinct and well parted. Their curve on the surface below the suture shows the old sinus. On the base they are radiating and are crowded and irregular, except round the umbilicus, where in the first two or three striae they are very sharp and distinct.

Rafinesquina's members were epifaunal, meaning they lived on top of the seafloor, not buried within it, and were suspension feeders. Rafinesquina normally have a concavo-convex profile, with radiating striae of alternating size which are crossed with finer concentric striae. Their width is usually greater than their length, like most Strophomenids. Members of this genus had shells that grew in increments, with each increment forming a layer of the shell (much like trees do with their rings).
|
|
The body colour of the species varies from black (dorsal) to brown (ventral), legs may be a red-brown. To reduce the abrasion of the ventral abdomen, ventrites 3–5 are covered in a large number of setae, which is one of the distinguishing features of this species. To further identify M. aberrans from other Mecodema species there is a difference in the size of the asetose punctures along elytral striae 9 in comparison to striae 1.

There appear, besides, upon the body whorl, oblique striae of growth pretty apparent, and presenting sometimes the appearance of varices. One or two striae separate also the folds from the upper marginal edge. The aperture is oblong, slightly narrowed, dilated at its base, where it is terminated by a very deep and slightly oblique emargination.

These skin marks are symptoms of pregnancy caused by the tearing of the dermis, resulting in atrophy and loss of rete ridges. These scars often appear as reddish or bluish streaks on the abdomen, and can also appear on the breasts and thighs. Some of these striae disappear with time, while others remain as permanent discolorations of the body. Mechanical distension and rapidly developing areas of the body during pregnancy (such as the abdomen, breasts, and thighs) are most commonly associated with striae formation.

In 1986 cut marks were found on the top of the skull of Engis 2, which were later identified as to be preparation damage " formed during restoration of the vault, moulding striae formed when mold part lines were incised into the fossil and profiling striae formed when craniograms were made with sharp steel instrument tips." The findings are preserved at the Collections de Paléontologie Animale et Humaine of the University of Liège. The bone fragments called Engis 3 have gone missing. The evolutionary origin of an ulna (forearm bone) fragment called Engis 4 discovered in 1872 is unclear; it has to date not been associated with a specific taxon.

Lancisi described the corpus callosum as the "seat of the soul, which imagines, deliberates and judges."Andrew P. Wickens, A History of the Brain: from Stone Age Surgery to Modern Neuroscience (2014) His Dissertatio Physiognomica provided the supporting argument in 1713. He opposed alternative locations of the soul as hypothesized by others, such as the centrum ovale, by Andreas Vesalius, and the pineal gland, by René Descartes. He hypothesized that the Longitudinal striae (later named in his honor as the "striae lancisi" or "nerves of Lancisi") were the conduit between the anterior location of the soul, and the posterior location of sensory organ functions, both within the corpus callosum.

The surface is finely corrugated. The folds are strong, close and numerous, not extending quite to the row of holes. Their summits are crenulated by inconspicuous spiral striae. Outside of the row of holes the surface slopes flatly to the strong angle or carina at the columellar margin.
|
|
The peripheral anal sinus is deep. The columella is somewhat swollen, sometimes showing a pleat. The paucispiral protoconch consists of 1 to 3 conical or globose whorls, smooth or with faint spiral striae. The operculum has a broadly oblanceolate to ovate shape, with an eccentric to terminal nucleus.
|
|
The shell has a more or less distinct peripheral angle, visible also at the base of the upper whorls. The sculpture has slight, microscopical, close-set spiral striae and prosocline growthlines. The umbilicus is lacking, although there is sometimes a small chink. The aperture has a straight columellar border.
|
|
The length of the shell attains 7 mm. The shell is minutely tuberculate at the shoulder-angle, and covered by minute revolving striae. Its color is whitish, with a large dorsal brownish spot or stain.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The spiral striae are weak, not prominent, and sufficiently impressed. They traverse the ribs and their interstices; They decrease in number towards the siphonal canal as they become more stronger and higher. The only copy of this species has the apex fractured. There are only 5 whorls left.

Paraptila symmetricana is a species of moth of the family Tortricidae. It is found in Bolivia. The length of the forewings is about 9 mm. The ground colour of the forewings is dark brown in the basal area, followed by a grey-brown area with yellow-brown striae.
|
|
Some submarginal striae can be seen. A black marginal line runs from the apex to the tail, and a very narrow line with three spots inside it from the tail to anal angle. Cilia black tipped. left Larva pale reddish yellow, tinged green, with reddish transverse stripes dorsally.
|
|
They are spirally sculptured with inequal lirae, the intervening furrows sharply squamose with striae of increment. The round aperture is produced into a projecting angle posteriorly and frequently disconnected from the body whorl. It is white and pearly within, rounded or slightly produced below. The outer lip is crenulate.
|
|
Wickham's striae often can be seen during microscopic examination of cutaneous lesions of lichen planus. To confirm the diagnosis of cutaneous lichen planus, a skin biopsy can be done. A punch biopsy of sufficient depth to the mid dermis is usually significant. Immunofluorescence studies are not always needed.
|
|
The base of the shell is flattened, with about twenty-five revolving striae. The thick columella is not reflected, but its base is somewhat grooved or depressed behind it. The aperture is about one-third of the length of the whole shell. It is rhomboidal, pearly, and smooth.
|
|
Their interstices bear granose riblets, and sharp oblique striae. On old individuals the disparity in the size of the lirae of the upper surface is often scarcely apparent. The base of the shell bears much finer, closer, granulose lirae. The aperture is very oblique and has a subtetragonal form.
|
|
The sharp incremental striae are microscopic. The apical whorls are white and eroded. The remainder is covered with a regular, elegant, minute reticulation formed by the intersection at right angles of two sets of obliquely descending black or bluish lines. The body whorl is subangulate at the periphery.
|
|
Their sculpture contains 7 to 8 spiral striae and incremental lines. The body whorl is obtusely angular at the periphery, rather convex beneath, slightly impressed in the region of the umbilicus. The lightly grooved aperture is subcircular-quadrate and iridescent within. The lip is within a trifle thickened.
|
|
The forewings are grey, with the tips of the scales dark fuscous and with irregular indistinct dark fuscous transverse striae, in the cell more broken into dots. The area of the cell and median area of the costa is somewhat suffused with darker but undefined. The hindwings are grey.
|
|
The five whorls are very convex and smooth. Only under a strong lens very faint growth striae and microscopic punctuations may be observed. The sutures are well-marked and marginated. The body whorl is rounded, with a convex base and a small perforation, nearly concealed by the columella.
|
|
Moreover the whole base is covered with microscopic radiating striae, beautifully waved in an S-like manner. The umbilicus is moderately wide, pervious, and funnel- shaped. Its wall is wave-striated, with a shallow spiral groove terminated by a tooth on the columella. The aperture is irregularly subquadrate.
|
|
The base of the shell shows under a lens very fine, close, regular spiral striae. Well-preserved specimens show red and emerald-green reflections through the thin layer overlying the nacre, like fiery opals. The low spire has a conoidal shape. The sutures are linear and not impressed.
|
|
In many cases the oblique folds are not apparent, and sometimes the transverse striae have wholly disappeared. The epidermis is of a deep brown. It varies also in its coloring, which in some specimens is of a bright yellow or violet, surrounded with one or several reddish bands.Kiener (1840).
|
|

|
Blue ice is found in some areas. Glacial activity has altered the volcano, generating glacial striae and roches moutonnees on the older volcanic rocks and frost shattering landforms and solifluction ridges. Glacial drift lies on the ice-free southwestern flank. In turn, glacial moraines have been overrun by lava flows.
|
|
The others are less convex adorned with more pronounced decurrent striae. They show, below the suture, a quite acute projecting keel, that extends around the base of the body whorl. The aperture is oval, angular at the top. The columella is arcuate, surrounded by a callous bead, acuminate at the base.

The whorls are subconnate, surrounded at their upper part by an articulated band of white and brown. The body whorl is ornamented towards its base with numerous transverse fine striae. The aperture is narrow, of a violet color. The outer lip is obtuse, thick, almost straight, interiorly having small folds or teeth in large quantities.
|
|
The size of the shell varies between 17 mm and 59 mm. The shell shows fine revolving striae, somewhat granulous towards the base. Its color is chestnut, longitudinally streaked with white, with frequently an upper and lower band of white maculations.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The size of the shell varies between 35 mm and 79 mm. The shell is narrow, cylindrical, and encircled by minutely granose striae. Its color is whitish, broadly three-banded by oblong longitudinal clouds of orange-brown, the interstices brown-spotted.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The size of an adult shell varies between 20 mm and 69 mm. The spire is convex, rather obtuse. The body whorl is encircled by distant punctate striae. The color of the shell is rosy tinged with yellow and interruptedly banded with white blotches below the shoulder and in the middle of the body-whorl.
|
|
The size of the shell varies between 22 mm and 68 mm. The shellis encircled throughout with fine striae, which are sometimes granular. Its color is violaceous or brown, with a few lighter spots on the spire, and usually a light irregular band below the middle of the body whorl. The aperture is violaceous.
|
|
The shell contains about 10 whorls, The others are slightly concave above the suture and then slightly convex or almost flat. The whorls are crossed by 14-16 oblique longitudinal ribs. Very fine spiral striae, crossed by equally fine lines of growth, are observable under a powerful lens. The oblique aperture has an irregular shape.
|
|
The length of the shell varies between 15 mm and 111 mm. (Original description) The narrowly subulate shell is reddish brown. It contains 21 very flat whorls. These are sculptured with oblique, rather closely set transverse costae interrupted by spiral striae and two crenate sutural bands, the upper of which is much the broader.
|
|
A single brooded species, this is one of the smallest of the geometrids, with a wingspan of only 14–16 mm. The forewing ground colour is light greyish ochreous. There are numerous curved dark fuscous striae, the veins and costa are ochreous brown. The edges of the biangulate median band form dark costal spots.
|
|
The forewing has a dark ovoid discal mark. The forewings lack a tonal spot and the hindwings are whitish grey with dark striae, and a small discal spot. It flies at night in June and July and is attracted to light and can be found by day at rest on the trunks of large sallows.
|
|
They are a little gibbous above and below, obliquely undulate below the sutures, and frequently on the periphery also. The whole surface is more or less finely spirally lirate with subgranulose lirae. The convex base of the shell is concentrically lirate with about 7 granose narrow lirae. Their interstices are generally occupied by concentric striae.
|
|
The size of the shell varies between 8 mm and 18 mm. The depressed, rather thin shell has a small, conical spire. It is reddish brown, lighter beneath, or variously variegated. The surface is covered with close fine hair-like spiral striae, and with two low keels above the periphery, the upper one nodose.
|
|
The thin, ovate, rather solid shell has a moderately long and shining spire. Its height is 5 mm. The 3-4 convexly rounded whorls are marked with very fine oblique longitudinal striae. The inner lip is callous, slightly expanded at the base, indented at the umbilical region and with a groove behind the inner lip.
|
|
The surface is smooth, except for the base which contains two or three very faint concentric striae. The circular aperture has a continuous peristome. The columella has a thick callus that connects to the convexity of the penultimate whorl. it covers for the greater part the umbilicus, that is reduced to a narrow, arched chink.
|
|
It is marked with narrow, curved, rather widely separated longitudinal white streaks. The base of the shell is minutely dotted with white. The sculpture consists of numerous little-elevated spiral beaded lirulae, with many spiral striae between them. The base is flat and has coarser concentric subgranulose lirae, becoming finer toward the outer margin.
|
|
The nucleus is smooth. The next two whorls contain a few (3 or 4) lirae, which are slightly irregular, the upper one is beaded. The lirae become less distinct, being broader and flatter on the next whorl, and are transferred in distant striae with smooth interstices. The infrasutural beads, cease on the penultimate whorl.
|
|
Towards the keel, a few undulating spiral striae appear. This sculpture is crossed by small radiating riblets. The aperture is rhomboidal, very oblique, with sharp edges and an internal nacreous layer, at some distance from the margin, with 10 lirae near this margin, and a groove corresponding to the keel. The basal margin is smooth.
|
|
The forewings are silvery white with a black point at the base of the costa and a minute black spot on the vein near the base. There are subbasal black striae on and below the costa with an orange bar between them. The hindwing base is silvery white with a slight brown antemedial line.
|
|
The forewings are cinereous whitish with numerous radiate striae of deep grey to blackish. The costa is blackish and a distinct blackish stigma in the discal area. There is a group of blackish stigmata with distinct black but delicate scales at the apex. There is also a linear rust ochreous shade in the apical area.
|
|
Below the whorls are angulated and tuberculated at the angles. These rather sharp tubercles number 12 on the body whorl. The transverse striae upon the upper concave portion of the whorls are finer and less conspicuous than those below the row of tubercles. The aperture is narrowed in front and measures about ½ the total length.
|
|
Two or three of these spiral lines ascend the spire. Its sculpture consists of slight growth lines and fainter or wholly obsolete fine spiral striae above, and about 6 fine-spaced grooves around the umbilical region, stronger toward the middle. The conic spire has an acute apex. The about 6½ whorls are quite convex.
|
|
Total cortisol increases to three times of non-pregnant levels by the third trimester. The increased estrogen in pregnancy leads to increase corticosteroid-binding globulin production and in response the adrenal gland produces more cortisol. The net effect is an increase of free cortisol. This contributes to insulin resistance of pregnancy and possibly striae.
|
|
The height of the shell attains 11 mm, its diameter 14 mm. The rather thin, perforate shell has a conoid-depressed shape. Its; coloris very variable, whitish-buff or rosy, brown reddish, ornamented with rosy maculations and narrow spiral lines articulated with white. Transversely it is delicately sulcate, the sulci exquisitely decussated by incremental striae.
|
|
The shell size varies between 17 mm and 27 mm The ovate shell is slightly cylindrical and is blunted at its summit. The short spire is flattened. It is composed of five whorls. The two last whorls are much more swollen, and covered upon their whole surface with very fine and very close transverse striae.
|
|
Schoenotenes capnosema is a species of moth of the family Tortricidae. It is found in Australia, where it has been recorded from Norfolk Island. The wingspan is about 17 mm. The forewings are whitish with silvery reflections, crossed by numerous fine, wavy ochreous-brown transverse striae and with various small tufts of raised scales.
|
|
The first two whorls are rounded, destitute of spines or carina. The last three whorls are somewhat geniculate, angled at location of carina. The body whorl is large, sometimes with an occasional spine below the carina. The epidermis is light horn in color, nearly white at apex, with microscopic longitudinal revolving striae and shining.
|
|
Its color pattern is olive-green or brownish. The 6–7 whorls are slightly convex, obliquely finely striate, longitudinally finely plicate. The folds stand at right angles to the striae, and are interrupted one-third of the distance from the suture to the periphery by two spiral impressed furrows. The linear suture is undulating.
|
|
Many apocrine glands – a type of sweat gland – become inactive, and body odor decreases. Remaining body odor becomes less metallic, sharp, or acrid, and more sweet and musky. As subcutaneous fat accumulates, dimpling, or cellulite, becomes more apparent on the thighs and buttocks. Stretch marks (striae distensae) may appear on the skin in these areas.
|
|
The shell is generally globose with an open but narrow umbilicus, the surface commonly reticulate resulting from longitudinal lirae crossing transverse striae. The ventral lobe of the suture is rather narrow with a median saddle about or little less than half the height of entire lobe. The first lateral saddle is subangular to angular.
|
|
The coloration of this species is not very definite. The upper surface is blotched irregularly with pink and brown, and some spiral articulated lines. The base is a trifle paler The 4½ whorls are nearly smooth, and slightly convex. They are sculptured with few delicate, fine spiral striae, which are most conspicuous on the base.
|
|
Periostracum very thin or wanting. Protoconch depressed-conical, multispiral (in one species paucispiral). Teleoconch usually with foreign objects attached in spiral series to peripheral flange and, sometimes, remainder of dorsum, at least on early whorls. Operculum horny, yellowish to brown, nucleus lateral, with simple growth lamellae, sometimes with conspicuous radial striae or hollow radial ribs.
|
|
Occasional darker striae or grooves of Retzius result from systemic disturbances in the human body. For example, a fever can cause some lines to appear darker than those surrounding them. Normally, amelogenesis involves a period of enamel matrix formation and a rest period. In case of any disturbance, the rest periods are prolonged and occur close to one another.
|
|
The columella is stout, white, short, obliquely truncate in front. The siphonal canal is wide, short, slightly flaring. The base of the shell is somewhat constricted, with the spiral striae stronger than on the rest of the surface.Dall (1902) Illustrations and descriptions of new, unfigured or imperfectly known shells; Proceedings of the United States National Museum, v.
|
|
The length of the shell varies between 12 mm and 18 mm. The narrow shell is turriculated with acute shoulders and with the ribs strongly projecting above it and then running across to the sutures. The ribs number about sixteen, nearly straight, prominent, crossed by very close, rather fine revolving striae. The aperture is rather narrow.
|
|
The length of the shell varies between 5 mm and 13 mm. The shell has an ovate-fusiform shape, with a moderate, scarcely turreted spire. It contains six or seven round-shouldered whorls. The sculpture consists of about 24 sigmoid longitudinal ribs, evanescing about the middle of the body whorl, and close revolving striae across the ribs.
|
|
The excavation is crossed by curved riblets or plicae in its upper part, and the whole shell is covered with fine growth-striae. The body whorl is regularly attenuated below, with a rather short siphonal canal. The aperture is angular above and at the end of keel, with a probably shallow sinus, below the suture;. The peristome is broken.
|
|
Augacephalus breyeri females are 40-55mm in total length. The cephalothorax is 15-22mm long and 12-18mm wide, and sometimes has a "step" separating the cephalic region from the fovea. The cephalothorax has a radial pattern of orange striae set on a background of black setae, and the cephalic region has a black "mask". The fovea is shallow.
|
|
The white, slightly translucent fusiform shell has convex whorls with prominent, longitudinal costae about the whole length and sloping, equidistant striae. The shell grows to a length of 4 mm to 5 mm. The oblong aperture is somewhat rounded and its length is slightly less than the total length of the shell. The siphonal canal is wide open.
|
|
It is polished and reddish brown. It is followed by six subsequent whorls. The anal fasciole on the spire is depressed, very minutely spirally striated with a single fine thread near the posterior edge which is appressed at the suture. Other spiral sculpture consists of fine striae and three stronger threads with wider interspaces on the base.
|
|
The length of the shell varies between 7 mm and 11 mm. The small shell has a warm yellow brown color. It has a blunt short smooth protoconch of a 1½ whorl, followed by five or more subsequent moderately rounded whorls. The suture is distinct, appressed and moderately constricted with three or four fine spiral striae on the fasciole.
|
|
The whole surface is very delicately fretted with almost microscopic, crisp spiral striae whose course is not quite regular, and which are crimped or disturbed by the lines of growth. This sculpture is particularly sharp and distinct in the sinus-area. The colour of the shell is pure marble-white. The spire is very regularly conical.
|
|
The sculpture consists of oblique opisthocline axial ribs, 11 on the first whorl, increasing to 12–13 on the body whorl, from suture to suture, and obsolescent on the base. The shell shows fine spiral striae 6–7 on the first whorl, increasing to about. 25 (between sutures) on the body whorl, crossing the ribs. No cingulum.
|
|
The shell contains 7 whorls, the first 2½ yellow, rounded, forming a trochiform protoconch, sculptured with vertical riblets decussated by delicate, obliquely forward- descending striae. The junction of the protoconch and the sculptured shell is very oblique and sharply defined. The aperture is narrow, with a deep sinus above. The outer lip contains four small teeth within.
|
|
The shell is cerithiiform, strongly corded on the periphery, smooth above it, except a narrow granulated sutural band, below with oblique slight, ribs and revolving striae. The color of the shell is chocolate, the peripheral and sutural nodes whitish. The interior of the aperture is chocolate, with a white band. The length of the shell is 25 mm.
|
|
These markings also ornament the slightly coronated spire. The aperture is white with clouded bands corresponding with the exterior markings. The surface of the shell is more or less striate throughout, but the striae become more prominent towards the dark stained base.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The outer lip is thick, margined exteriorly, crenulated indistinctly upon the lower edge, and marked within with very distinct, transverse striae. The left lip is continued in front, in a thin leaf which extends a little over the columella. It is smooth interiorly, and edged throughout its whole length with a row of small drops.Kiener (1840).
|
|
The color of the shell is yellowish to orange-brown, with an obscure lighter band below the shoulder and in the middle, encircled by ridged striae, sometimes nearly obsolete above. The base of the shell is stained purple. The aperture is orange or violaceous, with a white central band. This species feeds mainly on small coral fishes.
|
|
The size of the shell varies between 25 mm and 69 mm. The shell is pear-shaped, with revolving striae. Its color is reticulated orange-brown with large and small triangular white patches, and zigzag longitudinal chocolate markings, mostly interrupted so as to form one or two bands. The interior of the aperture is light violaceous.
|
|
The length of the forewings is 12.5–14 mm. The forewings are whitish with longitudinal light brown longitudinal striae, more or less following the veins. The hindwings are whitish with a metallic hue, and a darker fringe. & , 2003: Description of two new species of Apostibes Walsingham, 1907 with some synonymic and phylogenetic accounts of the genus (Lepidoptera, Scythrididae).
|
|
On the body whorl they diminish very rapidly below the periphery, and the spiral cords are noticeably enlarged and prominent on the summits of the ribs. The 6th and 7th below the shoulder are white. From the shoulder to the suture the surface is buff-white, and the growth striae somewhat lamellar. Elsewhere the shell is dark mineral-red.
|
|
The shell of Clypeoceras is laterally compressed, involute, discoidal; whorls strongly embracing and deeply indented by the next inner whorl, increasing rapidly in height. Sides slightly convex, sloping outward to a rather narrow venter, which may be angular or rounded but never with keels or grooves. Surface smooth or ornamented with radial striae and folds. Body chamber short.
|
|
They had smooth cutting surfaces, and, unlike those of other therocephalians, lacked facets or striae resulting from abrasion and wear. The large saber-like canines are held within the maxillae, and are quickly identifiable features of Moschorhinus. They are especially thick and strong, and uniquely circular in cross-section. In length, these sabers are comparable to gorgonopsids.
|
|
The surface is scarcely shining and is sculptured with separated narrow spirals above, and very numerous finer ones, covering the spaces between them. The striae of growth are excessively close and fine, scarcely visible. The principal spiral threads are articulated white and pink, and a trifle crenulated. The base of the shell is smoother, with separated linear spirals.
|
|
The Cravenoceratidae is one of six families included in the ammonoid superfamily Neoglyphioceratoidea, which lived during the latter part of the Paleozoic era. Cravenoceratid genera have moderately evolute to involute, broad or thickly discoidal shells with a moderately narrow umbilicus. The surface is generally smooth, dominated by growth striae. Spiral ornamentation may be present, but reticulate ornament is absent.
|
|
The striae of the base become coarser toward the axis. The colour of the shell is dark olive-brown or greenish, minutely tessellated all over with a slightly darker shade of the same hue. The small protoconch is conical with two slightly spirally striated whorls. The teleoconch consists of five whorls, those of the spire keeled above the middle.
|
|
Kumatoeides is a genus of leaf beetles in the subfamily Eumolpinae. The genus is endemic to New Caledonia. The genus was first erected in 2018 by Spanish entomologist Jesús Gómez-Zurita. The generic name is the Latin transliteration of the Greek adjective κυματοειδής, meaning "corrugated", referring to the regular striae on the elytra of the beetles.
|
|
A series of very fine spiral striae cover all parts of the whorls. The aperture is not preserved in any of the specimens, but the fairly distinct growth lines show that the anal notch was broad and rounded. Marshall (1918), Fauna of the Hampden Beds; Transactions and proceedings of the New Zealand Institute, vol. 51, p.
|
|
It contains five slightly convex whorls, separated by a well-marked suture. At the top of each whorl, close to the suture, there is a very narrow, decurrent zone with many longitudinal striae. These end at the angle at the limit of the zone in a series of small tubercles. The rest of the surface shows feeble growth lines.
|
|
The height of the shell attains 12 mm, its diameter 10½ mm. The narrowly umbilicate shell has a conical shape. Its color is maroon or deep brown, with longitudinal undulating flames of white, continuous or interrupted into spots on the base. The elevated spire is conoidal and contains 6 to 7convex whorls, traversed by numerous spiral striae.
|
|
Oval-oblong in contour, the two sides are about equally curved. The surface is shining, very densely and minutely striate in the direction of the whorls. The color is very deep blackish-olive with white dots, or finely variegated and marbled all over with gray and olive-brown. Under a lens it is finely articulated on the striae.
|
|
The sculpture consists of narrow spiral riblets with interstitial smaller threads. The interstices are finely latticed by raised close longitudinal striae. The spire contains about four whorls with the last 1½ very rapidly widening, descending anteriorly. The large aperture is oblique, oval, lightly sulcate within and brilliantly iridescent, with red, skyblue and green reflections, neither predominating.
|
|
See also Telesphoros. According to "country people" (rustici homines), these and witches (striae) threaten infants and cattle.Filotas, Pagan Survivals, pp. 78–79; Sunt aliqui rustici homines, qui credunt aliquas mulieres, quod vulgum dicitur strias esse debeant, et ad infantes vel pecora nocere possint, vel Dusiolus, vel aquatiquus, vel geniscus esse debeat, cited by Du Cange as Homel.
|
|
The sutures are deeply impressed. The seven whorls are well rounded, with close lamellose incremental striae, and corrugated by obliquely descending subtuberculose folds. The base is flattened bearing concentric densely squamose lirae, deeply concave in the center, and indented in the place of the umbilicus. The aperture is transversely oval, very oblique, pearly and somewhat corrugated within.

Margarinotus is a genus of clown beetles in the family Histeridae. There are at least 110 described species in Margarinotus. Biolib This genus is mainly characterized by several characters of the male genitalia. Most species may be distinguished by the emarginate outline of the anterior margin of the mesosternum and by the complete inner subhumeral striae on elytra.
|
|
The suture is moderately impressed. There are five whorls. These are slightly convex, the last decidedly deflected toward the aperture, encircled by about fifteen subequal spiral lirae, separated by interstices about as wide as the ridges. The incremental striae are generally strongly developed, causing the liree to appear nodose or somewhat irregular, and the interstices to appear pitted.
|
|
The whole surface is faintly marked with remote spiral threads, and very faintly scratched with closer microscopic striae. The whorlz are bluntly angulated in the middle, and the last is so, besides, at the base below the periphery. This angulation meets the outer lip. The second and third whorls have two or three strong spiral threads.
|
|
The type specimen has 5½ whorls. This relatively large, solid species and it is distinguished from the Eostrobilops coreana and the Eostrobilops nipponica by the number of internal basal plicae (two). The growth wrinkles or striae are rather fine and somewhat sharp below the suture, but are not regular in development in the peripheral and basal parts.
|
|
The length of the shell varies between 60 mm and 100 mm. The large, solid shell has rounded whorls. It is variable in its external morphology, due to the presence or absence of spines. There are both smooth (except for growth striae close the lips) and spiny forms (with two rows of open-fronted spines on the body whorl).
|
|
There are about nine, flat whorls, encircled by numerous equal, finely-beaded lirae of which there are about 9 on penultimate whorl. The interstices are densely costulated by fine incremental striae. The body whorl is acutely angled at the periphery. It is flat below and nearly smooth toward the outer edge, and finely granose-striate on the inner half.

Triaxomera puncticulata is a moth of the family Tineidae. It found in Japan (Honshu, Kyushu). [2010]: Global Taxonomic Database of Tineidae (Lepidoptera) The wingspan is 10–14 mm for males and 14–16 mm for females. The forewings are black with white irregular narrow transverse striae around the basal one- third, halfway and two-thirds of the costa.
|
|
The base of the shell is nearly flat, with 10 conspicuous, beaded spirals and a few very thin ones near the aperture. Moreover, the whole shell is covered with oblique, undulating, slightly laminar, radiating striae, very distinct on the base. The aperture is subquadrate. The outer margin is thin, a little convex, with 5 spiral grooves.
|
|
The size of the shell varies between 9 mm and 22 mm. The shell is broadly umbilicated and the spire has a depressed conoidal shape. It is sculptured with very fine, hardly visible spiral striae and is otherwise smooth. It is very shining, ashen-whitish, painted with light yellowish to light brown confluent flammules above and at the umbilicus.
|
|
The sculpture is composed of oblique, radiating striae, more prominent on the upper whorls. The base of the shell is almost smooth, with a slight stride of growth and very fine concentric lines. The nacreous aperture is obliquely quadrangular. The basal margin is continuous with the columella, and is not angulated at its junction with it.

Protaconeceras is a deeply umbliciate, involute haploceratacean ammonite from the Lower Cretaceous included in the oppeliid subfamily Aconeceratinae. The shell of Protaconeceras has a crunulate keel, especially in the youth. Sides are slightly convex and are covered with flexious striae or flattened ribs that extend onto the ventral surface. Sutural elements are wider and shallower than in Aconeceras.
|
|
They are elegantly ornamented with elevated spiral ribs and longitudinal striae. The first whorl is nearly smooth. The body whorl is double as long as the spire It is tumid, dilated and ornamented with 3 elevated cinguli on the lower part, 2 less elevated ones above. The base of the shell has 6 granulose, minutely striated, concentric cinguli.
|
|
Its upper margin is thin, slightly broken, but judging after the growth striae, sinuous above, protracted towards the keel, which appears to have been tooth-like. The basal margin is sinuous in the same manner;. The columellar margin is sinuous, reflected, and forms an angle with the basal margin. The operculum is very thin, corneous, with few whorls.
|
|
The outer lip tis hick, accompanied at its external part, by a very apparent margin, and furnished internally with numerous fine striae. The external color of this species exhibits a reddish ground, with irregular spots, and transverse lines of a deeper tint. The band which surrounds the middle of the body whorl is much wider and darker colored.Kiener (1840).
|
|
The height of the shell attains 1 mm, its diameter 1.7 mm. This thin, white, translucent shell has a discoidal shape and is widely umbilicate. The flat spire consists of 4 whorls, including the 2 narrow, smooth, convex whorls of the slightly raised protoconch. The shell is ornamented with many radial riblets and intercostal spiral striae.
|
|
The length of the shell varies between 14 mm and 17 mm. The small, pretty thick shell is elongated and conical. It is formed of six distinct, slightly convex whorls. The surface of the upper whorls appears to be shagreened by very small tubercles, formed by a multitude of very approximate longitudinal folds and transverse striae.
|
|
Upon the lowest whorls the longitudinal folds disappear, and the transverse striae, on the contrary, become more apparent. The simple suture is accompanied by a small, very narrow scaffolding, formed by a row of granulations, a little larger, and like papillae. The whitish aperture is subrotund. The outer lip is smooth at its edge, and striated internally.
|
|
The line-like, elevated longitudinal striae of the sculpture are only weak, but are pretty sharply defined. They encircle the whorls at regular distances from each other, and are about one-fourth the width of their interstices. Sometimes there are still more delicate secondary threads between them. Of the first there are 10-12 on the penultimate whorl.
|
|
The rest contains 11 ribs that hardly stand out from the background and 3–4 spiral lirae (on the body whorl about 16). Between them are minute, granose striae. The spiral lirations, which are situated on the angle of the whorls, are rather stouter than the rest. They are a little noduled on crossing the ribs.
|
|
The shell is broadly oval to quadrate with the umbones distinctly anterior. The posterior hinge line is straight, the posterior margin truncate, and the anterior hinge line grades into the down-sloping anterior margin. It is prominent posteriorly, where the shell is conspicuously decussate. The surface has a sculpture of fine concentric striae and bolder radiating lines.
|
|
Ornamentation consists of a series of spines on either side as well as transverse striae which form a well developed hyponomic sinus (for the funnel) on the venter. Sutures are straight across the venter, but form a broad shallow lobe on the dorsum. The siphuncle is close to the venter, composed of straight and empty segments, i.e. orthochoanitic.
|
|
Characteristics of this species are: the whorls are divided by a nodose keel into a larger convex upper portion and a smaller channelled lower part. A second series of blunt tubercles adorns the upper edge of the whorls along the suture. Below there are slightly elevated striae. The body whorl has the base sharply separated by a second keel.
|
|
The darker fuscous striae are angulated and the postmedian line is biangulate. The posterior edge of the median band is marked with black, the subterminal line is interrupted into whitish dots and a small white tornal mark. The forewings have either a minute dark discal mark or are without a discal mark. Forewings with a crescentic pale tornal stain.
|
|
Retrieved June 11, 2017. The wingspan is about 30 mm. The forewings are ochreous grey tinged with purplish red brown and the veins of the costal half are streaked with blackish. There are traces of postmedial and subterminal series of slight brownish spots and the apical part of the costa and termen has a series of dark striae.

Since ancient times, pregnant women have sought remedies to prevent stretch marks during pregnancy. Both ancient Greeks and Romans used olive oil, while Ethiopians and Somalis used frankincense. Striae was first recognized by Roederer in 1773, and was later histologically described by Troisier and Ménétrier in 1889. In 1936, Nardelli made the first morphologically correct descriptions.
|
|
Below the keel are lines of growth, obscure traces of spiral distant incised lines, and numerous irregularly impressed striae, which are perhaps pathological. The base of the shell is moderately convex. The outer lip is thin, sharp, strongly protractive below the keel, above the latter with a wide, shallow anal sulcus reaching close to the suture. The body is polished, milkwhite.
|
|
The cords cover the body whorl. They are feebler on the periphery, coarser on the base There are also faint spiral striae here and there. The axial sculpture on the upper part of the spire shows 14 or 15 strong rounded ribs with wider interspaces, feebler on the penultimate whorl, becoming obsolete on the body whorl. The aperture is ovate.
|
|
The others are convex with an indistinct suture. The longitudinal ribs are dense and are crossed by two transverse striae on each whorl, subsutarally sulcate and decussate by small lirae. The superior part of the narrow, oblique body whorl is slightly rounded, the inferior part attenuate and elongate. The superior part of the columella is concave, inflated at the middle.
|
|
The apical whorls (in a worn state) are reticulate, and the residue of the shell is sculptured with longitudinal ribs, which fade out on the lower half of the whorls. There are also numerous rounded spirals cutting the ribs. Below the suture there is an excavated area, showing spirals and also arcuate striae, more numerous than the ribs. The columella is fairly straight.
|
|
The oblong shell is ovate The whorls are compressedly gibbous, forming a round shoulder, constricted and with revolving striae towards the base. Otherwise, the shell is smooth, except that the upper whorls of the spire are slightly longitudinally plicate. The color of the shell is whitish, under a very thin, smooth, yellowish brown epidermis. The inside of the aperture is often yellowish brown.
|
|
The inner lip is complete, applied, smooth. The columella is long and nearly straight. The axial ribs are oblique, fading out above the angle, rounded, nearly as wide as the spaces, ten in the penultimate whorl, absent from the base. The spiral lirae are crowded, fourteen in the penultimate, whorl, very close-set on the base, granulated by fine accremental striae.
|
|
The length of the shell attains 15 mm. (Original description) The short, stout shell has a smooth rounded whitish inflated protoconch of two whorls and eight subsequent whorls. The color of the shell is whitish or pale madder brown. The spiral sculpture consists of obsolete spiral striae, generally a little wavy, and often absent from a part or the whole of the shell.
|
|
The part below the excavation on the body whorl is lirate over its whole surface. The upper, excavated part of whorls is crossed by rather distant curved riblets, which, in crossing the infrasutural lirae, produce small beads. At last the whole shell is covered with fine growth striae and excessively fine granules. The body whorl is convex, strongly attenuated towards its base.
|
|
The shell grows to a length of 16 mm. The shell is sharply keeled and noduled on the periphery, with revolving striae below it, stronger towards the base. The shell is whitish, stained with chestnut at the apex and on the lower part of the body whorl. There is a row of chestnut dots between the nodules of the periphery.
|
|
The size of an adult shell varies between 25 mm and 47 mm. The shell lacks a sutural band or spiral striae. The knobs on the periphery are rather short, instead of terminating ribs as in Clathrodrillia gibbosa (Born, 1778). The shell is yellowish brown, spotted with chestnut and with one large spot on the back of the body whorl.
|
|
The size of an adult shell varies between 33 mm and 118 mm. The depressed spire is conical, with a shallow channel and revolving striae, sometimes tessellated with chestnut. The body whorl is rather narrow, somewhat convex, grooved towards the base, somewhat round-shouldered, rather thin. The color of the shell is white, yellowish and orange-brown, variously clouded and indistinctly banded.
|
|
VI, p. 81 (described as Conus circumcisus) The shell of Conus brazieri G. B. Sowerby III, 1881 is rather solid, with revolving striae throughout. Its color is whitish, tinged with pale rose-pink, with two broad, light yellowish brown bands, sprinkled here and there with a few very minute brown spots. The spire is conspicuously marked with dark brown blotches.
|
|
Females of M. incognita are pear-shaped with no posterior protuberance. Their stylet ranges from 15-16 µm long, and knobs are rounded and offset. Perineal pattern is oval to rounded, typically with high dorsal arch, striae usually wavy, and lateral field absent or weakly demarcated. Males have a not offset head with an elevated labial disc without lateral lips (usually).
|
|
The ovate shell is elongated, slightly turreted and pointed at the summit. The spire is composed of seven very convex rounded whorls, united by a shallow suture. Upon the whorls are regularly disposed longitudinal ribs or folds, crossed by numerous, fine, approximate striae, which, by their mutual intersection, cover the surface of the shell. The white aperture is slightly rounded.
|
|
The epidermis is greenish. The slightly pointed spire is composed of six whorls, which are slightly convex, and united by a pretty delicate regular suture. The aperture is oblong ovate and effuse towards the base. The outer lip is smooth and white, marked interiorly, at a short distance from the edge, with sixteen or eighteen transverse striae of a reddish brown.
|
|
The edge of the angle in young specimens, is more prominent, and bordered by a row of pretty apparent tubercles, which disappear with age. The sutures are slightly perceptible. The first three upper whorls are covered with very approximate small longitudinal folds. The others are ornamented externally merely, with numerous, regular transverse striae, between which are distinguished other very delicate ones.
|
|
The size of the shell varies between 22 mm and 50 mm. The color of the shell is pink-brown, maculated or strigated longitudinally with light chestnut, with chestnut- dotted revolving striae, and a ceritall white, chestnut maculated band. The convex spire is maculated with chestnut.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The spire is broadly conical, but little raised, and rather sharply angled. The whorls are slightly concave above the angle, separated by a well-defined impressed suture, sculptured with three rather deep spiral grooves, and crossed by numerous rather prominent oblique striae. Interior of the aperture is pink. G.B. Sowerby III, Descriptions of Five New Species of Shell; The Journal of Malacology v.
|
|
The body whorl is subacutely angled above, then a trifle convex at the sides, and being much attenuated anteriorly has a somewhat piriform appearance. It is sculptured with fine lines of growth and transverse indistinct striae or shallow grooves, which around the base are much deeper. The aperture is very narrow. The outer lip is thin and moderately sinuated above the angle.
|
|
There are many valleys from the north through the south, which give the whole area a hilly character. In addition to rift valleys, there is also evidence of the last ice age with glacial boulders and glacial striae. Rock piles, which previously served as landmarks and were visible from afar are now surrounded by forest. The geological formation in the area is granite.
|
|
Forewings with traces of a waved antemedial line. A large irregular rufous and fuscous ocellelus at end of cell, with a ring of bluish-silver scales on it. Hindwings with a fulvous and silver line on discocellulars. Both wings with a curved and slightly sinuous postmedial black specks series, with a series of fuscous spots, beyond series of black striae.
|
|
Moreover, the shell is covered with fine spiral striae and growth lines, and is crossed by thick, rounded, oblique ribs, 12 in number on the penultimate whorl, which give the shell an elegantly beaded appearance. The last rib before the peristome is very thick. The aperture is elongately oval. The peristome is thick, with a rather shallow sinus above, protracted lower on.
|
|
The spiral lirae number about 6 on each whorl, but often double as many, by the intercalation of riblets in the interstices. The periphery has a prominent keel, cord-like, with secondary spiral striae, or bifid, cut into compressed granules, somewhat prominent above the sutures. The base has about 8 concentric ribs. The interstices are radiately striate, sometimes with a central riblet.
|
|
The height of the shell attains 6½ mm, its diameter 7 mm. The small, narrowly perforated shell has a conoidal shape with five whorls. The first is whitish-rosy, the following white, with reddish flammules and spots of green and bluish, especially at the ridges. The surface of the whorls is marked with very fine spiral and vertical striae, and 2 elevated carinae.
|
|
Two of the upper whorls are chequered as it were by intersections of striae. The suture is a little flattened, and slightly channeled. The ovate aperture is white, colored with red at the bottom. The outer lip is arcuated, and presents externally a projecting margin, which is crenulated outwardly by the jutting of the ribs, undulated externally, and dentated within.
|
|
The nucleus is obsolete. The next whorls contain spirals and radiating ribs, forming small spines when they cross. On the last three whorls the ribs disappear and only the spirals remain, the uppermost being in the last 5 whorls, conspicuously the largest. These lirae are closely beset with compressed spines, which resemble squamae, with very fine growth striae in the interstices.
|
|
The shell of the adult snail varies between 12 mm and 20 mm. The shell is numerously narrowly and delicately longitudinally ribbed and is latticed by revolving striae. The shell is yellowish white, interruptedly narrowly brown-banded at the slight shoulder, and occasionally tinged with brown elsewhere.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The whole surface bears numerous low, smooth spiral striae, which are often subobsolete on the body whorl, and it is then nearly smooth. The base of the shell is concave in the middle. The aperture is rounded-quadrate, smooth within or finely lirate. The columella is slightly sinuous, bidentate at base, expanding in a callus above, which slightly impinges upon the umbilicus.
|
|
Towards the keel it has very irregular radiating ribs, which leave however a nearly smooth zone above the keel, with only a few spiral striae. The base of the shell is less convex than the upper part. Some specimens lack the rose-coloured line round the umbilical callosity. The aperture is oval, thick, with the nucleus in the external lower corner.
|
|
The rest of the surface is smooth and shining, with a slight nacreous lustre and with numerous fine growth striae. The body whorl is conspicuously keeled below the periphery and with a second keel at some distance on the smooth base. The aperture is subrhombic. The outer margin is thin, angulate at the end of the lower row of nodules.
|
|
They are separated by deep sutures, encircled by three principal granulose carinae, the base and interstices with smaller lirulae and regular incremental striae. The whorls of the spire contain two strong, granose carinae. The body whorl is more rounded at the periphery than is usual in Calliostoma. The base of the shell is rather flattened, with about 10 concentric lirae, dotted with brown.
|
|
The 5-6 whorls are somewhat flattened below the sutures, with a superficial spiral line, and marked with light incremental striae. The large apertureis very oblique, ovate, silvery inside and rounded below. The outer lip is slightly fluted within. The white columella is wide and beas on its face a longitudinal rib which rises in the region of the umbilicus.
|
|
In larger individuals the first are not very apparent because of the depth of the grooves and the height of the striae that inintersect. The whorls are convex and rounded, and they show above, around the suture, a small canal, marked by arched lines coming from the growth lines of the shell. The base is narrow, elongated and somewhat recurved. Brocchi G.B. (1814).
|
|
Oblique axial striae crowd between the granules on the spire, but are obsolete on the base. The aperture is quadrate oblique. The outer lip is crenulate, toothed just within the margin opposite each spiral lira, within this thickened and wrinkled, and in the throat lirate and nacreous. The basal lip is crenulate, thickened within with 5 teeth gradually enlarging towards the columella.
|
|
The surface is lusterless, with scarcely visible growth striae. The shell is opaque-white, radiately striped with olive- bordered red lines, generally interrupted and forming a tessellated white and dark pattern. The apex is minute, recumbent, spiral, dextral. The inside of the shell is brilliantly iridescent, not showing the color pattern clearly except at the red-and-white spotted margins.
|
|
Geisonocerina has an orthoconic shell with transverse lirae and striae that are periodically thickened. Internal features are similar to Geisonoceras wherein the siphuncle is subcentral with short straight necks and connecting rings that expand slightly into the camerae and in which there are annulosiphonate deposits in the more adapical (juvenile)portion of the siphuncle and cameral deposits in the adapical (early) chambers.
|
|
The punctures are from where pilosity arises, and these are often elongated on the dorsal and ventral portions of the head. On the thorax, striae are present, but they are less engraved with fewer punctures than in S. richteri. On the petiole, the punctates are located on the sides. The postpetiole, when viewed above, has a strong shagreen with distinct transverse punctostriae.
|
|
The apertural border is straight and horizontal. The surface is covered by fine, closely packed, radiating striae and a few concentric lines of growth. The shell has been thick, as may be seen by a few fragments which are left along the borders. The length of the shell is 24 mm, width 20 mm and the height of the shell is 15 mm.
|
|
The length of the shell attains 20 mm, its diameter 6 mm The dark red shell has a very long and turreted spire. The shell contains 9 whorls. It is smooth, and the very fine spiral striae can only be seen through a lens. The 10 longitudinal ribs are rounded and smooth, but become acuminate at the base of the shell.
|
|
The species have whitish or yellowish ground coloration, the pattern is brownish, consisting of indistinct marginal spots and some transversal striae or stripes. Male genitalia: resembling Celestica but uncus bilobate and strongly sclerotized. Tegumen very narrow dorsally, valvae tripartite into various shaped lobes of a complicate structure; no gnathos; aedeagus about as long as saccus, tubular and simple, no cornuti or coremata.Gozmány, 1965.
|
|
These transverse striae are definite and at regular distances; six or eight appear on the body whorl. The operculum is very small, unguiculated, pointed, and of a reddish brown.Kiener (1840). General species and iconography of recent shells : comprising the Massena Museum, the collection of Lamarck, the collection of the Museum of Natural History, and the recent discoveries of travellers; Boston :W.
|
|
The nuclear whorl is smooth, the remainder clathrate with strong spiral ribs crossed by elevated, close, vertical striae, which crenulate the ribs and cut the interstices into pits. There are 3 stronger spirals on the penultimate whorl, with a riblet in each interval. On the earlier whorls there are only 3 spirals. The body whorl at its termination has about 27 spirals.
|
|
The small spire is very short. The four whorls are convex, the inner 1½ are smooth, the rest have strong, separated spiral lirae, the interstices wider than the lirae, rendered pitted by raised, regular rib-striae each interliral interval with a central spiral thread. There are 3 principal lirae on the penultimate whorl. The outer lip is inserted on the fourth.

Lebedodes ianrobertsoni is a moth in the family Cossidae. It is found in Tanzania,Afro Moths where it has been recorded from the central subregion of the Eastern Arc Mountains probably extending further east into the drier coastal forests. The length of the forewings is about 9 mm. The forewings are pale orange-yellow with buckthorn brown transverse lines and striae.
|
|
The length of the shell attains 5.5 mm, its diameter 2.5 mm. The white, elongate fusiform shell contains 6- 7 whorls of which 2 in the protoconch. These are intermediary convex with linear sutures, discreetly undulant. The shell shows many longitudinal striae and oblique ribs. It shows manyrounded ribs, 12-146 in the penultimate whorl and 10-12 on the body whorl.
|
|
The length of the shell varies from 12 mm to 20 mm. The ovate, conical shell is pointed at the summit. The pyramidal spire is formed of six or seven distinct, smooth, convex whorls. These are covered with very prominent, convex, longitudinal folds, intersected only at the base, and upon the two or three upper whorls, by a few pretty deep transverse striae.
|
|
The suture is very apparent, and a little canaliculated. The white aperture is ovate, narrowed at its upper part and dilated inferiorly. The outer lip is thin and is ornamented interiorly with numerous transverse striae. The smooth columella is arcuated at its base and is covered throughout its whole length with the inner lip, the base of which is a little thicker.
|
|
The length of the shell varies from 15 mm to 30 mm. The ovate, conical shell is pointed at the summit . The pyramidal spire is formed of six or seven distinct, smooth, convex whorls. These are covered with very prominent, convex, longitudinal folds, intersected only at the base, and upon the two or three upper whorls, by a few pretty deep transverse striae.
|
|
The shell has 5 whorls which are rather flattened; the upper ones are striatulate, the final whorl with irregular and waved rib- striae. The base of the shell is convex, spotted with chestnut, scrobiculate in front. The shell aperture follows the slope of the spire, is semicircular, and is contracted by six strong, curved lamellae. The peristome is white, broadly expanded and reflexed.
|
|
The shell size varies between 16 mm and 32 mm The shell has an ovate, ventricose shape. The pointed spire is composed of six or seven convex whorls. It is ornamented upon its whole surface with granular, longitudinal folds, and transverse striae. The suture is very distinct, formed by a small canal, and bordered with closer tubercles, principally upon the body whorl.

Epicephala laeviclada is a moth of the family Gracillariidae first described by Hou-Hun Li in 2015. It is found in the Chinese provinces of Guangxi and Hainan. The length of the forewings is 5−7.5 mm. The forewings are brown to dark brown with three white striae from the costal , and extending obliquely outward to the width of the forewing.
|
|
The shell of an adult Glycymeris nummaria can be as large as . It is quite thick, almost circular in shape, with a sculpture of radiating striae and fine concentric lines. The surface is dull and may be dark or pale brown, but also whitish-yellowish. Inside of the shell is glossy, white or pale yellow, often with irregular brown markings.
|
|
The subsequent whorls are angular, very convex, separated by a linear, undulated suture, accompanied by a faint infrasutural rib, more conspicuous on upper whorls . The upper part of whorls is conspicuously excavated, the lower part contains strong, short, nodulous, oblique ribs, abruptly ending at the excavation, scarcely reaching the basal suture in the lower whorls. There are 3 faint, raised, spiral lirae in the excavation, crossed by elegantly curved, partly riblike striae, 4 to 5 stronger lirae crossing the ribs, with a few faint striae above them on the limit between ribs and excavation in the lower whorls. On the penultimate whorl, another liration appears at some distance above the suture, amounting to 3 rather remote, strong lirae on the body whorl, and a large number (about 20) on the basal part of the body whorl and siphonal canal.
|
|
The ovate aperture is whitish, contracted at the top by a transverse fold of the left lip. The outer lip is emarginated at its upper edge, marked interiorly with transverse striae in great numbers. The left lip is obliterated and flattened at its summit. It gives rise from the middle to the base to a pretty thick, projecting callosity, in the form of a keel.
|
|
By interposition of additional spirals each double bead extends into a short oblique nodose rib. Below the suture is an indefinite band, followed by a distinct and excavate fasciole. The latter is sculptured with fine lunate striae. On the body whorl anterior to the fasciole are about twenty-three prominent but irregular spiral cords, some of which are rendered nodulous by passing over the ribs.
|
|
The 6½ remaining whorls are separated by a conspicuous, simple suture. They are convex and slightly excavated at their upper part. The sculpture consists of numerous, very irregular, spiral striae, more conspicuous at the base of shell and siphonal canal, scarcely traceable in the excavation. The upper whorls show a peripheral row of obtuse tubercles, which in the uppermost whorls have the character of ribs.
|
|
The spiral sculpture consists of fine sharp equal and equidistant striae covering the shell in front of the carina, cutting minutely the summits of the ribs, with wider flattish interspaces. The aperture is rather wide and simple. The siphonal canal is short, deep and recurved.

The size of the mollusks shell reaches up to 15 mm in length and is light yellowish white in color. The shell shows four or five revolving ridges on the body whorl, with intermediate close revolving striae. There are no longitudinal ribs except on the upper whorls of the spire, subcontinuously three-varicose.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The spire is gradated, the whorls straight-sided in the anterior three-fourths, and bevelled at an angle of 45° to the posterior suture, which is distinct and simple. The sculpture consists of five longitudinal ribs, continuous, narrow, erect and prominent. The interspaces are nearly flat, giving a pentagonal section. The spiral sculpture consists of Sublenticular inconspicuous longitudinal and spiral striae, which cross the ribs.
|
|
The length of the shell attains 9 mm, its diameter 3¾ mm. (Original description) The thin, white shell has a biconical shape. It contains about 10 whorls, of which about 4 form a red- brown protoconch, with convex whorls, of which about 1½ upper whorls are smooth. The other ones show angular riblets, strongest near the upper suture, crossed in their lower part by fine, oblique striae.
|
|
This area is decorated with regular and tightly arched lines of growth, more accentuated near the suture, and decurrent, very weak striae. The rest of the whorls are decorated with numerous and irregular growth lines and very shallow and slightly wavy decurrent ribs. The body whorl measures slighly over 3/4 of the total height. The broad aperture is elongatedly oval and angular at the top.
|
|
The length of the shell attains 7 mm, its diameter 2.5 mm. The shell has an ovately acute shape with 6-7 slightly convex whorls. The surface of this small monochrome brown snail is characterized by fairly dense, rounded longitudinal ribs, covered by regular raised striae, forming a coarse grid. The aperture is narrow and somewhat shorter than half the length of the shell.
|
|
The length of the shell attains 16 mm. The elevated spire is acute, with a ridge below the sutures. The 8 longitudinal ribs are rounded, oblique, crossed by close strong striae, and terminate above on the periphery. The color of the shell is yellowish brown with two chestnut bands, or the lower one broader so as to cover the lower portion of the body whorl.
|
|
The spire contains 11 convex whorls; separated by a wide and deep depression with the suture in its bottom. The first two whorls are smooth and shining, forming a blunt apex. The next whorls show revolving striae and 7 - 8 axial ribs, often with small brown spots, terminating in the middle part of the canal. This siphonal canal is short, wide and somewhat notched.
|
|
The shell has an elevated, tuberculated spire. The surface is irregularly clouded with chestnut or orange and white, and minutely marked with interrupted narrow brown or orange revolving lines, more or less broken up into articulations. Upon the lower half of the body whorl these lines become striae, and are distantly, minutely granular.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The size of the shell varies between 40 mm and 80 mm. The shell is subcylindrical, with fine revolving striae. It has an orange-brown color, very finely reticulated with chestnut, with larger subtriangular spots of white, aggregated into masses and bands at the shoulder, middle and base. There are usually a number of longitudinal streaks of chestnut running over the orange-brown reticulated spaces.
|
|
The length of the shell varies from 9 mm to 20 mm. The small shell is ovate, conical, rather shining, and pointed. The spire is formed of six or seven indistinct whorls, often ornamented with longitudinal folds, which are rarely continued to the base of the body whorl, and which are crossed by very fine and slightly marked transverse striae. The aperture is white.

|
Gasconsoceras is a genus of nautiloid cephalopods belonging to the tarphyceroid family Barrandeoceratidae, known from the Middle Silurian. Shells of Gasconsoceras are rapidly enlarging gyrocones and serpenticones covered by fine transverse and longitudinal striae and prominent dorsal and lateral transverse ribs. A fair degree of mobility is indicated by the deep hyponomic sinus. Other than being between center and venter, the siphuncle is poorly known.

|
Abapertural view of the shell of Conus striatus The large, slim shell has a varying length between 44 mm and 129 mm. It is irregularly clouded with pink- white and chestnut or chocolate, with fine close revolving striae, forming the darker ground-color by close colored lines. The pointed spire is tessellated with chestnut or chocolate brown and white. Its shoulders are rounded and its sutures deep.
|
|
The forewings are glossy white and thickly scaled, with traces of a waved fuscous antemedial line except towards the costa. There is a faint sinuous medial line angled outwards beyond the cell and ending at the submedian fold. There is a rather more distinct subterminal line, excurved from below the costa to vein 2, then oblique and sinuous. There is also a terminal series of blackish striae.
|
|
Tefflus is a genus of large, black and flightless Afrotropical ground beetles in the tribe Panagaeini. They are broadly similar to the Anthiini ('oogpisters'), but are not colourful, and have a six-sided and flattish pronotum. The distinct longitudinal carinae (ridges) on their elytra are separated by two rows of punctures running along the striae (grooves). Males have some segments of the forelegs enlarged.
|
|
The 7 to 9 perforations are rather small and a little raised The right side is straighter than the rounded left margin, and the back is depressed. The color of the shell is scarlet-red, more or less marbled with olive-green, painted with broad white rays. The spiral riblets are numerous, unequal, separated by deeply cut grooves. Their summits are cut by fine radiating striae.
|
|
Below it is traversed by 7 to 8 spiral granose ribs, above it with longitudinal, oblique, rather separated striae and two spiral, slightly marked series of granules; The body whorl is obtusely bicarinate. The slit fascicle has a semicircular, delicate, impressed stride. It has a round and very deep, pervious umbilicus. The species has a (thin yellow in juvenile examples) operculum that completely seals the subquadrate aperture.
|
|
The last whorl descends very deeply toward the aperture, with a strong keel at the shoulder, occupied by the anal fasciole, and another keel at the periphery, the space between them concave. Below this carina there are about 3 rather separated spiral lira, and around the umbilicus three more. The keels are obsolete for a short distance behind the aperture. The fine growth striae are scarcely perceptible.
|
|
Intervals of the wings (elytra) are moderately raised on the central upper surface (disk). The wings are also hairless. The wings are rectangular (oblong), narrower than the base of the prothorax but with the shoulder part (humeral) slanting, the longitudinal depressed line (striae) is deep and not punctured (impunctate) and the intervals plane, the puncture on the third interval is about the middle (median).
|
|
The size of the shell varies between 10 mm and 60 mm. The large, solid but not thick shell has a rounded-oval shape and is much depressed. The distance of the apex measures from the margin one- fifth the length of the shell. The shell is sculptured with fine spiral cords cut by close minute striae of increment, and has radiating waves or folds above.
|
|
The base of shell is sculptured with two spiral grooves and a number of very fine spiral striae. It is painted with a zone of fine, closely set cinereous flammules, within which is a second zone almost uniformly of the same colour. The umbilicus is whitish, wide, deep, and bears several small, indistinct, spiral, crenate riblets. The outer margin is surrounded by a coarsely crenulate carina.
|
|
The Anochetus ambiguus type specimen is well preserved, though it shows some distortion from the amber moving after entombment and is missing some body structures. The second specimen has an estimated body length of . The mesosoma has distinct fine striae covering most of its surface and the gaster is smooth and shiny. The upper side of the head, mandibles, pronotum, and gaster sport sparse erect hairs.
|
|
The height of the shell attains 8 mm. The imperforate, dull white shell has an ovate-conic, subventricose shape. The apex rather obtuse. The shell is ornamented with strong spiral subnodose ribs, decussated by elevated rib-striae cutting the interstices into square pits, of which there are 3 or 4 series on the third whorl, 4 on the penultimate, and 7 on the last.
|
|
The heigfht of the shell attains 7½ mm, its diameter 5¼ mm. The shell is ear-shaped, with a minute spire and a very large, convex body whorl. Its surface is somewhat shining, black with scattered whitish dots, spots or zigzag lines. The shell is sculptured by numerous close microscopic spiral striae, several smaller alternating with larger ones, and somewhat decussated by impressed growth lines.
|
|
Meyrick described the species as follows: Although very similar in appearance to its close relative X. semifissata, Meyrick states it can be distinguished from that species by the distinctive form of the posterior edge of the median band and the less distinct pale striae beyond it. Hudson also points out that the hindwings are dark ochreous in colour and lack the transverse markings of X. semifissata.
|
|
The teguments are soft or subcoriaceous. The striae of the cephalothorax and of the three last abdominal segments are very distinct; those of the anterior segments are scarcely or not at all distinct. The anterior and lateral borders of the cephalothorax are smooth. The eye eminence is relatively small; smooth or, rarely, provided with small, slightly distinct, tubercles; widely separated from the cephalic border.
|
|
The cancellation of the body whorl is strongly developed, so that the pittings between the cross- ridges are deep and striking. The suture is deep and channelled. The uppermost of the six revolving lirae borders the channelled suture, and the umbilicus is encompassed by a swollen ridge, which is in addition to the six line referred to. The microscopic striae are seen upon the lirae.
|
|
The upper angle is acute, continuing nearly to the apex. The whorls are concave above, slightly excavated around the periphery, a little convex beneath. They are encircled by numerous unequal spiral threads, the larger ones beaded, the smaller irregularly crenated by rather decided incremental striae. The base of the shell is radiately striate, with about 8 to 12 smooth spirals, their interstices without secondary riblets.
|
|
The shell is umbilicated, ovate, conic above, moderately solid, brown with a buff line at the periphery, very delicately sculptured with lines of growth, and sometimes has low wrinkles and fine impressed spiral striae. The spire of the shell is conic. The apex is obtuse. The sculpture of the nepionic whorls (the whorls immediately following the embryonic whorls) has superficial vermiculate (worm-like) wrinkles.
|
|
The longitudinal striae of growth are numerous, very fine, and slightly apparent. The aperture is narrow, for it is much contracted by two protuberances situated upon the two lower thirds of the columella. The outer lip is arched, flattened, widened within, having a wide longitudinal ridge outside of it. It has, on the inside, the whole length, from sixteen to eighteen ridges, or very strongly prominent teeth.
|
|
The base of the shell is very flatly rounded with 7 concentric narrow lirae, the inner 4 closer than the rest, which are separated by 4 to 6 interlirate striae. The umbilicus is narrow, minutely axially incised. The aperture is oblique and roundly quadrate. The outer lip is slightly convex, thin, and smooth within The margin is sinuously convex below the suture, and concave towards the periphery.

Adult beetles of S. lineatus measure 3.4-5.3 mm in length. They are characterised by a series of coloured scales arranged in alternating lines (striae) on the elytra; it is from this characteristic where the species gets its name lineatus meaning 'lined' or 'striped'. The head and pronotum also have fine pointed setae amongst the scales. The antennae are clubbed, pointed and preceded by 7 segments.

Louis Wickham's grave in Neuilly-sur-Seine community cemetery. Louis Frédéric Wickham (28 February 1861, Paris - 14 October 1913, Mesnil-le-Roi) was a French physician and pathologist remembered for describing Wickham striae. He trained in medicine in Paris, receiving his M.D. in 1890. He studied dermatology at the Hôpital Saint-Louis in Paris before becoming physician at the Hôpital Saint-Lazare in 1897.

Lichen planus was first reported in 1869 by Erasmus Wilson. The origin of the word is believed to be from the Greek word ‘’ Leichen’’, which means tree moss; and also from Latin word ‘’planus’’ which means flat and even surface. Dr Wilson explained the condition as an inflammatory disorder with unknown etiology. Initially, the characteristic surface markings or striae was described by Weyl in 1885.
|
|
The size of the shell attains 50 mm. The spire can have a regular conical shape or convex and contains 12 whorls with rather deep, punctulated striae. The smooth body whorl is obtuse at its summit and shows a small number of grooves at its base. The aperture is narrow and becomes almost imperceptibly wider at its anterior extremity, ending in a rather deep indentation.
|
|
The size of the shell varies between 7 mm and 12 mm. The thin, perforate shell has an orbicular-conoid shape with irregularly transversely costate striae. The color is various, it is purplish, maculate with whitish, orange-yellow or rose-red, with traces of clear spots at the suture, or else purple-red with white flecks. The 5 whorls are moderately convex, separated by a distinct suture.
|
|
The thorax is almost identical, but the clear space between the metapleural striate area and propodeal spiracles is either a narrow crease or not present. The side portions of the petiole are punctate. The sides of the postpetiole are opaque with punctures present, but no irregular roughening is seen. The anterior of the dorsum is shagreen, and the middle and rear regions bear transverse puncto-striae.
|
|
The length of the shell varies between 44 mm and 100 mm. The whorls are subangulated with about twelve oblique, rounded, longitudinal ribs below the angle. The surface is decussated by growth lines and small revolving striae. The shell is yellowish white, with orange-brown bands on the shoulder, at the base and intermediately three in all, the upper one appearing on the spire.
|
|
Scarites buparius reach a length of about , with a maximum of .CSMON-Life The basic black color of this glossy beetle is aposematic, highlighting clearly the body on the sandy substrate. Elytra present thin and shallow striae, almost absent in larger specimen. Sexual dimorphism is not conspicuous,Galerie-insecte but males are usually slightly smaller than females and the mandibles of the males are longer and hooked.
|
|
The aperture is white and the lip is bordered with dark brown. Faint spiral striae sculpture the embryonic whorls, and later whorls are convex and irregularly wrinkled in the direction of growth-lines. The whorls are convex and the last is often very obtusely angular at the periphery. The aperture is strongly oblique and the lip thickened within by a strong rib near the margin.
|
|
The sutures are surrounded above by a small band of alternating white and red spots, while the lower part is marked by another brown band, sometimes broken by distant white spots. The middle of the body whorl is surrounded by a subcrenulated red band, interrupted by white spots. At the base of the whorl are seen transverse striae, and a small brown band. The aperture is ovate.
|
|
Most species of wentletrap are white, and have a porcelain-like appearance. They are notable for their intricately geometric shell architecture, and the shells of the larger species are prized by collectors. The more or less turret-shaped shell consists of tightly-wound (sometimes loosely coiled), convex whorls, which create a high, conical spiral. Fine or microscopic spiral sculpture (also called "striae") is present in many species.
|
|
The interstices are slightly broader than the riblets. They are crossed by spiral threads,4 fine and close together on the shoulder, 1 on the carina of the whorl, and 3 below it, the uppermost of these at some distance from the keel. The crossing-points are produced into small oval gemmules. The base is spirally striate, all the striae in front of the aperture being smooth.
|
|
The rest are slightly convex and longitudinally ribbed. The ribs are stout, broader than the interstices, suberect, a little arcuated. Those on the body whorl become obsolete a trifle below the middle, whence downward the whorl is transversely finely striated, the striae at the extremity being closer together than those above. The aperture is small, ovate, occupying about one third of the entire length.
|
|
The upper two are smooth by erosion, the following whorls are obliquely coarsely plicate and finely wrinkled in the same direction above, somewhat shouldered. They are obtusely angular near the periphery, above which several obscure beaded lirae revolve, shagreened by intersection of incremental striae and oblique wrinkles. The base of the shell is nearly smooth. The oval aperture is very oblique and silvery within.
|
|
Microcondylaea compressa can reach a length of about and a width of . Shells are quite elongated and laterally compressed. The external surface is light brown to brown with living mussels (empty shells are often coloured dark brown to black) and shows shallow concentric striae of growth. Typical for this species are the tree-like ("arboriform") siphonal papillae - all other European freshwater mussels have undivided papillae.
|
|
The various species of Euglandina are similar in numerous ways. The shells are simple, oval in outline (sometimes broadly so), but occasionally more-or-less straight-sided, the lip of the aperture is also simple, without any thickening. These shells may be brown, orange, or pink in color, or some intermediate shade. Shell sculpture when present usually consists of striae that mark progressive growth increments.
|
|
The outer lip is varicose and strongly sinuate at its top. The columella is almost straight and has a thin callus. This species is remarkable on account of the fine transverse striae which cover the entire surface, also for the prominent columellar callus and the deep rounded sinus of the labrum. The upper ends of the ribs are cut off by a shallow groove or depression.
|
|
Lyecoceras is a gender of slender endogastrically curved orthocerids, so determined by identification of the hyponomic sinus on the concave side. The siphuncle is dorsal of the center, toward the convex side of the shell. The surface has faint longitudinal striae and is encircled by weak annulations. Lyecoceras was first found in the Middle Silurian of Sweden, and since in the Silurian of Sochuan Provence, China.
|
|
It consists of fibers that are said to arise in the parolfactory area, the gyrus subcallosus and the anterior perforated substance, and course backward in the longitudinal striae to the dentate gyrus and the hippocampal region. This is a cholinergic bundle of nerve fibers posterior to the anterior perforated substance. It interconnects the subcallosal gyrus in the septal area with the hippocampus and lateral olfactory area.
|
|
The ovate shell is oblong, transverse, equilateral and inequivalve. The beaks are small; that of the left, slightly notched. The valves are white, diaphanous and smooth, indistinctly marked with striae of increase, rounded at the anterior side, strongly truncated at the posterior side. The side is bounded outwardly by an obtuse angle, pretty prominent, extending obliquely from the beak to the lower part of the shell.
|
|
The body whorl is encircled beneath the principal keel by about ten lirae, whereof the uppermost is the stoutest, the rest gradually becoming finer towards the base. The interstices between them crossed by elevated striae or lines of increment. The aperture is small, brownish, occupying about three-sevenths of the entire length of the shell. Its slit is situated in the concavity above the principal carination.
|
|
The outer lip is effuse, externally much thickened, deeply notched near the suture. The lip and columella in most specimens are dark ferruginous brown. G.W. Tryon adds to the above description that the interspaces of the ribs, in one of his specimens, are covered with fine revolving striae, and that another has a faint central band.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The whorls are moderately convex. The spiral sculpture consists of (between the sutures four, on the body whorl about a dozen) strong rounded close-set cords closely undulated behind the periphery by numerous low narrow axial riblets with about equal interspaces. The cords in front of the periphery are not undulated, but extend to the end of the siphonal canal. There are also very fine axial striae in the interspaces.
|
|
The length of the shell attains 10 mm. (Original description) The pure white shell is fusiform and slender.. The longitudinal sculpture shows six narrow subacute prominent ribs on each whorl, which are sinuated posteriorly on the right side, and which are continuous along the spire like a species in the genus Murex.The spiral sculpture consists of very numerous microscopic spiral striae in the intercostal spaces. The apex is acute.
|
|
The decurrent striae are somewhat thin, regular, spaced, continuous, very attenuated at the top of the whorls, scarcely more marked at the base of the body whorl along the siphonal canal. The striations are strong, irregular, very wavy-flexuous. They form in the concave region of the whorls small corrugated folds, very close together. They blend in the body whorl, with the prolongation of the nodules of the keel.
|
|
The striated zone of the cuttlebone is concave, with the last loculus being strongly convex and thick in the front third. The sulcus is deep and wide and extends along the striated zone only. Striae (furrows) on the anterior surface form an inverted V-shape. The limbs of the inner cone are very short, narrow, and uniform in width, with the U-shape thickened slightly towards the back.
|
|
The space between the longitudinal ribs has a red color These interstices are as long as the ribs. The oblique ribs are numerous and increase from 11–12 on the early whorls to 18 on the body whorl, extending almost to the siphonal canal. The spiral striae show obsolete grooves and are best seen on the early whorls. The oval aperture has a length of about the length of the shell.
|
|
There are six above the angulation, and two below it. Fine accremental striae can be seen under the lens. The suture is distinct, linear, undulating, convex between the ribs. The body whorl is oblong with two median rounded carinae, the upper larger, more prominent, forming the angulation (in the spire whorls), the lower producing the upper margin of the suture, tuberculated by the axial ribs, which cease at the lower one.
|
|
Moreover, fine growth-striae and excessively small granules are visible on the whole shell, by the aid of a strong lens. The body whorl is regularly attenuated towards its base, only slightly convex, with a very short, broad siphonal canal. The aperture is obliquely oblong, with a sharp angle above and a narrow gutterlike siphonal canal below. The peristome is thin, with a wide, moderately deep sinus above.
|
|
The oblique ribs (14–15 on the penultimate whorl) are crossed with regular elevated ridges, which are less distinct below the sutures, from which descend very fine and close-set crescent-shaped striae (10–12 on the penultimate whorl) as far as the angle of the whorl, crossing the concentric lines. The spire is sharp. The apex is dark brown or purple. The aperture is elongately ovate, brown within.
|
|
The length of the shell attains 33 mm. The shell is yellowish brown, within and without, with a narrow lighter band on the periphery, and sometimes a row of white dots on the ribs a little below the middle of the body whorl. There are a few revolving striae at the base of the shell.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
Female: Differs on the upperside in having the area surrounding or bordering the ocelli on both forewing and hindwing paler, closely irrorated (sprinkled) with brown striae, the discal transverse band generally clearly defined, and very often both the tornal, and at least one of the apical, ocelli distinct. On the underside it is paler than the male, and has the subbasal, discal and subterminal transverse dark bands more clearly defined.
|

Elytra show ten extremely fine striae. Hind femora are glabrous.Roberto Arce-Pérez y Miguel Ángel Morón The genus Hydrophilus (Coleoptera: Hydrophilidae: Hydrophilina) in Mexico and Central America Instituto de Ecología, A. C. Hansen, M. 1991 The hydrophilid beetles: phylogeny, classification and a revision of the genera (Coleoptera, Hydrophiloidea) Biologiske skrifter, 40 These beetles are adapted for aquatic life. The first-stage larvae and the adults are excellent swimmers.
|
|
The outer lip is subtruncated, somewhat denticulated upon the lower edge, and marked with transverse striae internally. The columella edge is covered by a pretty thick callosity, spreading a little upon the belly of the shell.Kiener (1840). General species and iconography of recent shells : comprising the Massena Museum, the collection of Lamarck, the collection of the Museum of Natural History, and the recent discoveries of travellers; Boston :W.
|
|
Sometimes its ground is red ; and white, undulated, very crowded flames, or brown and distant longitudinal lines ornament it from one end to the other. At other times it is whitish, which happens when it has been a long time exposed to the light ; and in this case transverse striae are perceptible on its surface. But the articulated band about the suture always appears in each of these varieties.Kiener (1840).
|
|
The size of the shell varies between 17 mm and 65 mm. The shell is encircled throughout with coarse or fine striae, which are sometimes granular; violaceous or brown, with a few lighter spots on the spire, and usually a light irregular band below the middle of the body whorl. The aperture is violaceous.G.W. Tryon (1884) Manual of conchology, structural and systematic, with illustrations of the species, vol.
|
|
The size of the shell varies between 8 mm and 9 mm. The rather solid shell is light yellowish-brown, ornamented with large irregular white patches, which are mostly longitudinally oblong and here and there zigzag. The patches at the angle are smaller and arranged in a regular way. The growth lines form slightly waved longitudinal striae, crossed by very faint spiral ridges, which become stout and prominent towards the base.
|
|
The protoplasm of Vorticella is typically a translucent blue-white colour, but may contain a yellow or green pigment. The food vacuoles may show as a brown or grey colour, but depends on the food eaten. Zoochlorellae, food reserves and waste granules, which are abundant in the cytoplasm, may create the impression that Vorticella is an opaque cell. Vorticella has a pellicle with striae running parallel around the cell.
|
|
The smooth shel lshows distant revolving striae, the upper ones nearly obsolete. The spire is concavely depressed, with a raised pink apex and is somewhat tuberculate. Its color is yellowish with a band of irregular white blotches dotted and shaded with chestnut in the center, and smaller ones at the upper part and base.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
The entire surface is peculiarly sculptured with longitudinal striae. The spire is rather obtusely convex and obsoletely coronated.G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol. VI; Philadelphia, Academy of Natural Sciences It is possible that this is a compound species as there are at least two population groups where the shell morphology is identical but the animal, habitat and behaviour are totally distinct.
|
|
The inner lip is narrow, smooth, applied, free at the front, with a callus posteriorly at the junction with the outer lip. The columella is subconcave, joining the body whorl at a very open angle. The spiral sulcations are equidistant, 9 in the penultimate, 17 in the body whorl. The axial accremental striae, distinct under the microscope, cross the spirals, sinuous, comparatively distant, especially on the body whorl.
|
|
Thalassoceratoidea, formerly Thalassocerataceae, is a superfamily of Late Paleozoic ammonites characterized by their thick-discoidal to subglobular, involute shells with narrow or closed umbilici and biconvex growth striae with ventral sinuses. The ventral lobe of the suture, which straddles the outer rim, is wide, and bifid, with a tall median saddle. Thallassoceratoidea are gonitites and one of seventeen superfamilies in the Goniatitina suborder. Two families are now included, Bisatoceratidae and Thalassoceratidae.
|
|
The front and side-slopes are slightly convex. The posterior slope is nearly straight, with a very small impression below the nucleus, This nucleus is smooth, compressed, subspiral, placed at a little more than 6/11 of the total length of the shell. The sculpture consists of a few concentric striae. Moreover, the whole surface is covered by very small, crowded granules of an irregular oval, potatolike shape.
|
|
The sculpture consists of irregular concentric rugosities or wrinkles, generally more distant from each other towards the apex, more crowded towards the margin, with a tendency to form lamellae. On some parts the upper side of the rugosities has coarse, short, riblike radiant striae, wanting in other places, perhaps by erosion. The inside of the shell has a smooth surface. The rhachidian tooth of the radula is elongate with convex sides.
|
|
Sometimes it may lead to striae on nipples, mainly a preceding symptom of septation mastitis. Engorgement usually happens when the breasts switch from colostrum to mature milk (often referred to as when the milk "comes in"). However, engorgement can also happen later if lactating women miss several nursings and not enough milk is expressed from the breasts. It can be exacerbated by insufficient breastfeeding and/or blocked milk ducts.
|
|
The length of the shell attains 28.5 mm, its diameter 7.5 mm. On the penult whorl there are sixteen axial ribs, crossed by five or six narrow spiral cords. On the body whorl there are about eighteen narrow, spiral cords, which are slightly enlarged where they cross the ribs and widely spaced in the peripheral region and above. Between them are many minute spirals and rather sharp axial striae.
|
|
The height of the shell attains 4⅓ mm, its diameter 2½ mm. The shell is limpet-like, but with a recurved beak projecting beyond the posterior outline of the aperture. The shell is very convex, sloping convexly toward the front margin. The surface of the shell is lusterless, showing under a lens rather rude concentric growth lines, and very numerous, close, fine striae, radiating from the apex to the margins.
|
|
The base is slightly concave to almost flat, sculptured with fine, irregular, subspiral striae which run at almost right angles. The aperture lower lip is somewhat thickened in mature specimens, often with a distinct internal thickening in middle of lip and usually with a weakly sinuate edge. Color-wise, it is yellowish-white dorsally, with base yellowish-white and collabral lines of chocolate brown. The callus is white.
|
|
Forewings with some black strigae from the costa. Six oblique fuscous bands, one sub-basal, another on discocellulars, the others medial, postmedial, sub- marginal and marginal. Some fuscous striae found on each side of the sub- marginal band. Hindwings with a fuscous band on inner margin joined at anal angle by a band from the upper angle of cell and almost met by one from the costa beyond the middle.
|
|
The body whorl goes slightly down to the aperture. The surface is smooth, except for the base of the body whorl, which has, seen from the periphery, low concentric striae, that disappear at a considerable distance from the umbilicus. The circular aperture has a continuous peristome. The columella has a thick, narrow callus that hardly reflects on the umbilical opening in young specimens but cover it completely in adults.
|
|
Between these and the sutures are four or five smaller and closer ribs of a similar character, and on the base of the body whorl about eight ribs which are less nodulous and scabrous than those above, the interstices being crossed by fine striae. The spire is somewhat elevated. The aperture is nearly circular and pearly within. The columella is thickened, terminating in a blunt callosity at the base.
|
|
The surface of the shell is finely spirally striate, the striae about 8 on the body whorl, with a couple of stronger ribs at the periphery, which are visible above the suture on the spire whorls. The short spire is conic, acute, with its lateral outlines rectilinear. The 7–8 whorls are flat, the last one acutely carinated, and flat beneath. The oblique aperture is rhomboidal, smooth and nacreous within.
|
|
Sculpture : prominent spiral keels, three to the penultimate, ten to the body whorl, successively diminishing from the suture to the base. They are undercut below the narrow summit, parted by much broader flat interstices. These keels, apparently folds in the shell substance, are microscopically beaded by fine radial striae, represented in the interstices as hair lines. The protoconch does not share the adult sculpture, but is minutely malleated.
|
|
It is ornamented with waved zigzag and acutely angular light and dark brown streaks. The 5½ whorls are slightly convex, moderately sloping, separated by simple, deep-channeled sutures. The spire shows only here and there very faint traces of obsolete spiral striae. The broad body whorl convex above with small erect slightly angular nodules in three rows, the two rounded at the periphery, depressly convex at the base.
|
|
Angioid streaks, also called Knapp streaks or Knapp striae are small breaks in Bruch's membrane, an elastic tissue containing membrane of the retina that may become calcified and crack.DermAtlas - Johns Hopkins Up to 50% of angioid streak cases are idiopathic. It may occur secondary to blunt trauma, or it may be associated with many systemic diseases. The condition is usually asymptomatic, but decrease in vision may occur due to choroidal neovascularization.
|
|
The 8 to 9 whorls are flat or a trifle concave They are acutely carinated with the carina a trifle projecting above the sutures. The upper surface of each whorl is encircled by 10 to 12 spiral lirae. These are only slightly elevated, and show strong, regular oblique striae of increment in the interliral interstices. The base of the shell is flat, with about 10 concentric narrow lirae.
|
|
Larva The ground colour of the forewings is pale grey brownish or fuscous, occasionally with an ochreous tinge, darker along the costa, and are marked with distinctive pale fascia and a whitish tornal spot. The forewing patterning is dominated by a conspicuous, dark discal and smaller costal spots. The obtusely angulated dark grey striae are not defined except on the costa. There is a pale interrupted subterminal line.
|
|
The length of the shell varies between 6 mm and 24 mm. The elongated shell is narrow and turreted. It is formed of nine or ten very distinct whorls, slightly convex, ornamented with a great number of ribs formed like folds, subnodulous, approximate, numerous, and slightly raised upon the lowest whorl. These ribs are apparent only at the upper part, whilst the base is provided with transverse striae, easily distinguished.
|
|
They are separated by a somewhat convex smooth fasciole from a thread-like keel above the periphery. In front of this is a wide, smooth interval. On the base of the shell are about a dozen spiral threads with wider interspaces, and very faint microscopic spiral striae are visible in all the interspaces under a lens. On the upper whorls there is a small thread between the keel and the suture.
|
|
The spire contains about 6 whorls, of which about one forms the blunt, smooth nucleus. The next whorls, including the penultimate, have only one strong median keel. The space above and below this keel is slightly concave, with a few microscopic spiral threadlike striae. Two whorls next to the nucleus are crossed by conspicuous radiating riblets, straight but in an oblique direction above the keel, convex below it.

Skin changes in Cushing's syndrome include thinning and bruising easily, developing striae and hyperpigmentation at skin folds. The hormonal changes can lead to hirsutism, males developing breast tissue, females no longer having periods and both sexes may become infertile. High cortisol levels can lead to psychological disturbances such as anxiety or depression and insomnia. Bone health can deteriorate, leading to an increased fracture risk in people with Cushing's syndrome.
|
|
There are about six ribs on a whorl, oblique, subnodose at the middle, attenuating at both extremities and not reaching to the upper suture. The transverse striae are rather coarse, minutely decussated by the flexuous lines of growth. The body whorl shows a third brown zone below the middle. The aperture is whitish within, ornamented with the three exterior bands, occupying about four elevenths of the entire length of the shell.
|
|
The sutures are either simple, linear, or somewhat canaliculate. There is a concavity in the subsutural area. The about 5 whorls are spirally transversed by excessively minute spiral striae. The body whorl has an acute nodulous carina at the periphery, and another angulation or keel at the middle of the upper surface of the whorl and continued upon the spire, and which is usually nodose on the body whorl.
|
|
Epicephala domina is a moth of the family Gracillariidae. It is found in China (Hainan). The length of the forewings is 7.5−11 mm. The forewings are greyish brown to deep brown with three pairs of white striae from both the costal and dorsal margins at two-fifths, three-fifths and four-fifths extending obliquely outward to the middle as well as to end and outside of the cell.
|
|
The remaining whorls are acutely carinate, with an area below the suture, either smooth or with arcuate striae. Below the carina appear numerous longitudinal riblets, decussated by spiral carinations, giving the shell a somewhat prickly or nodulous appearance. The aperture is small, with a well-marked sinuation above. The columella is vertical, a little twisted at the base.Sykes E. R. 1906 On the Mollusca procured during the “Porcupine” Expeditions 1869–1870.
|
|
The length of the shell attains 15mm, its width 9mm The thick shell is ovate and inflated. Its ground color is white, covered with transverse striae and longitudinal waving reddish lines, often divided into three portions in their length. The conoid spire is canaliculated, composed of six whorls, the upper ones very approximate, the lowest much larger than all the others. The oblong aperture is widened, dilated at its base.
|
|
The axial sculpture consists of (on the body whorl 16) rounded narrow riblets crossing the whorls and obsolete on the base. The spiral sculpture consists of (on the spire three, on the body whorl four) prominent rounded cords. These are more or less nodose at the intersections with the ribs, and between the cords two or three fine threads and a few finer striae. The posterior cord forms a shoulder to the whorl.
|
|
The body whorl shows a cord at the suture and on the other side of the anal fasciole about five elevated keels with subequal interspaces, more adjacent on the base with about as many more smaller and closer threads on the anterior region. The suture is appressed and obscure. The anal fasciole is concave, not spirally striated The axial sculpture consists of rather close sharp striae which cut the spirals. The aperture is narrow.
|
|
The siphonal canal is short and wide. The sculpture consists of fine, close, undulated spiral striae and axial folds, which, in adult specimens, often, almost disappear on the ultimate whorl, whilst they, invariably, are recognised on the upper whorls. The teeth in the radula are ensiform with a short manubrium.Friele H., 1877: Preliminary report on the Mollusca from the Norwegian North Atlantic Expedition in 1876; Nyt Magazin for Naturvidenskaberne 23: 1–10, 1 pl.
|
|
In the first small whorls it is undulated or obscurely nodulous, but in the last four or five whorls not so. From it the posterior part of the whorl ascends to the suture almost in a straight line or section of a cone, the anterior slope is full and rounded. The anal fasciole is polished and marked only by the fine silky incremental striae. The other transverse sculpture consists solely of fine incremental lines.
|
|
The sculpture consists of longitudinal ribs, narrower than their intervals, 10 on the body whorl, and with excessively fine striae, visible only with the aid of a lens. The aperture is narrow, measuring less than half the total length of the shell. The columella is a little excavated at the top, slightly twisted at the base. The outer lip is smooth on the inner side, with a sinus on top and inflected below the sinus.
|
|
The spiral sculpture consists of (on the penultimate whorl about nine) strong flattish threads, equal all over the surface and without intercalary striae. They have narrower interspaces on the spire and equal or wider ones on the body whorl. The axial sculpture consists of (on the body whorl about 10) sharp-edged narrow nearly straight ribs reaching nearly to the siphonal canal from the fasciole, with much wider interspaces. The narrow aperture is dark purple.
|
|
The shell contains 7 whorls including a protoconch of two depressed whorls. Its sculpture consists of eight thick and prominent ribs to a whorl These descend the shell vertically and continuously; on the base they are slightly flexed, and each terminates anteriorly in a bead. Both ribs and interstices are engraved by very minute and dense spiral striae. The snout is traversed by a few coarse spirals, which cease at the bead row.
|
|
The subsutural band is distinguished from the rest of the surface only by the direction of the growth striae that are arched in the opposite direction. At the base of the upper whorls, there are some very short longitudinal threads. The top of the holotype is in very bad condition so we cannot see if these are the vestiges of a general sculpture of the embryonic whorl. The aperture is slightly pyriform.
|
|
The subsequent whorls are convex, separated by a deep, linear suture, the upper ones are strongly angular at the shoulder, the angle however is fainter on lower whorls and nearly disappears on the body whorl. A second prominent liration is visible on upper whorls, but becomes likewise fainter. Moreover the shell is crossed by numerous, fine, raised, spiral striae and finer axial ones, producing a fine cancellation. On the siphonal canal the spirals are stronger.
|
|
The body whorl is densely and evenly latticed by alternately larger and smaller spiral cords intersecting scarcely less prominent, but rather closer, longitudinal rib-striae. The color of the shell is pale brown, every fourth cord marked with brown in narrow lines along the cord, alternating with diffused white spots. A row of alternately brown and white squarish spots appear below the suture: the early whorls brown. The aperture is smooth within.
|
|
The subsequent whorls are scarcely convex, with only a trace of being divided into two parts on the upper two. However, the upper part is marked with elegantly curved, conspicuous riblets, being slightly bead-like just below the suture, on a narrow, infrasutural spiral. The lower part of the body whorlshows numerous, faint, spiral striae, becoming stronger on the rather long, slender siphonal canal. Moreover the lower whorls display elegantly waved growth-lines.
|

The size of an adult shell varies between 24 mm and 52 mm. The shell is bulbous, with a convex, striate spire. The body whorl is striate, the striae rounded, usually obsolete above, granular below, olive, chestnut-, chocolate- or pink-brown, variously marbled and flecked with white, often faintly white-banded below the middle. In the variety nigropunctatus, the shell is colored as above and encircled by series of chocolate-colored dots.
|
|
The upper whorls are convex, loaded also with compact folds and transverse striae. But in these the tubercles are slightly perceptible, and upon some specimens not at all. The white aperture is ovate, and terminates at the summit by an excavated notch at the top of the outer lip, and by a fold of the inner lip. The depth of the cavity is brown or of a violet-color, marked with transverse, whitish bands.
|
|
The white aperture is ovate, rounded, terminated at its upper part by an angle of the outer lip, and a thick ridge of the left lip, which form a canal. The emargination at the base is oblique. The outer lip is thick, furnished upon its edge with six or seven spinose teeth, and in the interior with numerous transverse striae, very fine, and slightly apparent. The left lip is smooth, and obliterated above.
|
|
The length of the forewings is 16–19 mm. Forewing with innumerable fine, slightly oblique, transverse striae, no distinct lines; the postmedian on both wings indicated by a thick dark fuscous shade posteriorly, distally to which (especially on hindwing) there is an ill defined purplish blotch reaching to the hinder angle. Ab. atrox Zerny is a melanotic form, forewing mostly dark chestnut brown, towards the base and hinder angle black.Prout, L.B. 1912–16. Geometridae.
|
|
There is an S-shaped brown mark found on the discocellulars, where its center is outlined with reddish brown. Its edges are brown, and two white marks can be seen on it near its lower angle. An oblique ochreous fascia runs from apex to below angle of cell, where it is bent down to inner margin. A large greyish-brown patch is usually present between the fascia and outer angle, with pale striae on it.
|
|
In very large apertures, there is also a problem of lens sagging, a result of gravity deforming glass. Since a lens can only be held in place by its edge, the center of a large lens sags due to gravity, distorting the images it produces. The largest practical lens size in a refracting telescope is around . There is a further problem of glass defects, striae or small air bubbles trapped within the glass.
|
|
The sculpture consists of spiral series of closely set rounded granules, the series or cinguli a little separated on the upper surface, closer beneath. These number 17 or 18 upon the body whorl, the 7th being upon the periphery, just as in Clanculus clanguloides. The interstices between lirae are finely obliquely and spirally striate, the spiral striae often a little difficult to distinguish. This gives the interstices at times a granulate appearance under the lens.
|
|
The length of the forewings is 6 mm for males and 8.5 mm for females. The ground colour of the forewings is dark brown with scattered red-copper scales in the basal area, followed by a slate- grey area with dark brown striae. There is a silver-white patch bordering the costa and a dark brown band bordering the costal patch basally. The hindwings are whitish yellow with uniform light grey-brown overscaling.
|
|
Paraptila cornucopis is a species of moth of the family Tortricidae. It is found in Mexico in the Federal District and the states of San Luis Potosí, Colima and Veracruz. The length of the forewings is 6.9 mm for males and 6.8-9.5 mm for females. The ground colour of the forewings is dark red brown in the basal area, followed by a tawny-grey band, with faint purplish suffusion and irregular dark striae.
|
|
It is yellow when young but ages to a deep olive- brown color. Microscopically, B. ananas is distinguished by large spores with cross striae on the ridges and spirally encrusted hyphae in the marginal appendiculae and flesh of the stem. Previously known as Boletus ananas and Boletus coccinea (among other synonyms), the species was given its current name by William Alphonso Murrill in 1909. Two varieties of Boletellus ananas have been described.
|
|
The body whorl has a sharply angled periphery. The shell upper surface is circled by irregularly beaded bands, 5 or 6 on each whorl, uneven in size, the upper row largest;. The bead in each whorl is larger on the upper row than those at lower rows, The base of the shell is nearly flat, concentrically lirate. These lirae are granulose, rather coarse, with broad interspaces, which are frequently occupied by revolving lirulae or striae.
|
|
The upperside of the male is unusual in that it has only a small amount of pale orange on the discal area of the forewing below the cell; a pattern more reminiscent of females of the genus. The underside ground colour is light slate brown with a glossy sheen. The usual postdiscal striae or the genus are present in an ochreous colour and there is a diffuse ochreous marginal band on both wings.
|
|
The shell reaches a length of 16 mm, its diameter of 5.5 mm. (Original description in Latin) The shell is subulately turreted, longitudinally ribbed and transversely exquisitely striated, The whorls are smooth, canaliculate above, crossed by lunulate threads. The siphonal canal is elongate and recurved. (Original description in Italian) This is an elegant shell, whose surface imitates a very fine reticulation, by weaving the longitudinal ribs with the transverse striae which are very numerous.
|
|
The sutures are deeply impressed. The surface of whorls are encircled by narrow spiral lirae, separated by spaces about 1 mm wide (in a specimen of 15 mm diam.). These interstices are closely latticed by oblique raised striae, and bear on the last part of the whorl from one to three minute spiral interstitial threads. There are about 16 principal threads on the body whorl of the largest specimen, but this character is extremely variable.
|
|
Moreover, these interstices are filled with similar finer spirals as in the spire. The funnel-shaped umbilicus is moderately wide, and probably pervious. Its wall shows fine radiating striae and a conspicuous spiral groove, terminating in a strong dentiform projection on the columellar margin. The aperture is moderately large, irregular in shape, with a rather deep sinus at the suture (about 1½ mm, behind the most projecting part of the outer margin).
|
|
A band a little deeper colored covers the body of the body whorl, the base of which is furnished with pretty distinct transverse striae or furrows, five or six in number. The white aperture is ovate, terminated above by a sort of canal, indicated by a transverse ridge upon the left lip. The outer lip is thick, slightly denticulated towards the base, and deeply striated within. The columella is arcuated, the base spirally folded.
|
|
Paeromopodids possess 60 to 80 body segments and range from long and 2 to 8 mm wide as adults. Paeromopodids have distinct parallel grooves called striae on their body rings that give a somewhat roughened texture and distinguishes them from other cylindrical western millipedes. Individuals may be rather uniformly blue gray, or colored in alternating bands of light and dark brown, or may possess a dorsal lengthwise stripe of yellow or light brown.

A fossil cast of the shell of a Baculites grandis on display at the North American Museum of Ancient Life in Lehi, Utah. The adult shell of Baculites is generally straight and may be either smooth or with sinuous striae or ribbing that typically slant dorso-ventrally forward. The aperture likewise slopes to the front and has a sinuous margin. The venter is narrowly rounded to acute while the dorsum is more broad.
|
|
The body whorl is encircled by three prominent, equidistant carinae, one subsutural, composed of rounded or radiating knobs followed by two or three beaded lirulae, two at the periphery, prominently beaded, with a beaded riblet between them. The base of the shell is encircled by 5 more or less beaded, equal lirae. The entire surface is microscopically obliquely striate, and in some places decussated by microscopic spiral striae. The oblique aperture is rounded-quadrate.
|
|
It is characterized by its small size (13 mm), spindle-shape, whitish colour and smooth surface. The height of the shell is up to 13.4 mm, three times as long as wide, rimate, spindle-shaped, with slightly convex sides, rather thin. Colour is uniformly greyish-whitish or with axial streaks of light to dark-brown, the upper whorls somewhat darker; a dark band around the rimate umbilicus. Surface is hardly shining, with incrassate growth striae.
|
|
The ovate shell is oblong, transverse, equilateral, inequivalve and slightly inflated. it is of a reddish white color, covered with a browner shagreened epidermis, and marked with irregular and more or less numerous striae of increase. The beaks are short, and that of the right valve is notched at its summit to receive that of the left valve. The valves are pretty thick, rounded at the anterior, and truncated at the posterior side.
|
|
These three keels are in typical specimens adorned by sharp nodules, about 30 on the upper keel, 38 on the peripheral one, and 34 on the visible part of the lower one. Moreover there are 2 raised spiral striae between suture and upper keel, 5 between this and the peripheral one and 2 in the space between periphery and lower keel. This concerns the body whorl; on the upper ones, the finer sculpture disappears gradually.
|
|
The peristome is broken, according to growth striae with a very shallow sinus below the suture. The columellar margin is concave above, directed to the left along the siphonal canal, with a thin layer of enamel. The operculum is thin, corneous, with a terminal nucleus at the left side. The radula shows 2 rows of teeth, in about 12 transverse rows, each tooth with a rather sharp point and a deep sinus at its basal margin, separating .
|
|
The spiral sculpture consists of three or four threads with wider interspaces overrunning and sometimes slightly nodulating the peripheral ribs. In front of these on the base are about eight spiral threads conspicuously nodulous at the intersections with the minor ridges, and with much wider interspaces. On the younger shells these threads are more close set, fewer and less nodulous, the minor ridges inconspicuous. Finally between these in the adult are more or less distinct finer spiral striae.
|
|
The fasciole in front of it flattish, the anterior margin of the fasciole forming a more or less angular shoulder to the whorl. The axial sculpture consists of very fine incremental lines and at and near the shoulder of feeble fine flexuous wrinkles, stronger on the spire. The spiral sculpture consists of very fine close striae over the whole surface except a few threads on the siphonal canal. The body whorl equals about two- thirds the whole length.
|
|
The anal fasciole slopes forward flatly to the shoulder of the whorl with only arcuate incremental lines for sculpture. The axial sculpture consists of (on the body whorl about 20) obliquely protractive short ribs, strongest at the shoulder and on the body whorl stopping abruptly near the periphery. The spiral sculpture is hardly perceptible, on the base of the shell there are a few distant obsolete threads and faint microscopic striae. These vary in strength in different specimens.
|
|
These are followed by eight sculptured whorls. The suture is appressed, obscure, behind a strongly constricted anal fasciole sculptured with almost microscopic spiral striae. The other spiral sculpture consists of small obsolete threads covering the whole surface in front of the fasciole and three or four cords on the base of the body whorl widely separated and conspicuously nodulous where they cross the ribs. There are also 10 or more closer cords on the siphonal canal.
|
|
The length of the shell varies between 8 mm and 16 mm. The shell is finely reticulated by growth and revolving striae, with larger spiral lirae, crossed by non-continuous varices. The color of the shell is yellowish white, with minute white markings on the spiral ridges, and a large brown spot on the back of the body whorl apparent also within the aperture. G.W. Tryon (1884) Manual of Conchology, structural and systematic, with illustrations of the species, vol.
|
|
They have numerous spiral striae, crossed at right angles by others of about double strength, but the spirals are more numerous. The other whorls are ribbed longitudinally, the ribs having a slight spiral trend. These ribs terminate a little below the suture, the intervening space carrying rather closely set angularly bent threads. Under the microscope these are thickened at the base and sharp at the edge, resembling a propeller blade, their contour following the outline of the sinus.
|
|
The rest concavely slope above, then are obtusely angled about the middle, rounded, and much contracted beneath, obliquely plicated and spirally lirated. The plicae are rounded, oblique, but little elevated, more or less obsolete at the upper part. The transverse lirae are most beautifully and finely granulated. They are separated by deep-cut striae of different sizes, those in the concavity of the whorls subequal and finer than those beneath, which, again, are not all of uniform tenuity.
|
|
With the exception of the subsutural band, the surface is covered with microscopic striae, which, in intersecting the inconspicuous lines of growth, give a peculiar crinkled appearance to the surface. Bush, K. (1893). Reports on the results of dredging under the supervision of Alexander Agassiz, in the Gulf of Mexico (1877-78), in the Caribbean Sea (1878, 79), and along the Atlantic coast of the United States (1880), by the U.S. Coast Survey Steamer "Blake."

The size of an adult shell varies between 15 mm and 30 mm. (Translation of the original French description) The slightly shiny shell is solid and has an elongated fusiform shape. The turreted spire is composed of 9 very convex whorls, subcarinated on their extremes. They are separated by a very marked oblique suture, covered with sigmoid growth lines, fine decurrent striae and large, wide and nodular oblique longitudinal folds, numbering 6 on each of the last two whorls.
|
|
Another brown band extends always between the tubercles of the body whorl. The operculum is oval and rounded, membranous and denticulated upon one of its edges. This shell, which is very common, often varies in its form. The whorls are more or less elongated, the longitudinal folds and the transverse striae, sometimes completely disappear upon the body whorl, nevertheless, tubercles remain which cover this shell, and the furrows at the base, which are very well marked.
|
|
The size of an adult shell varies between 35 mm and 100 mm. The shell is bulbous, with a somewhat elevated, lightly striated spire and rounded shoulders. The body whorl is rounded with convex sides, sometimes with granular striae below. The shell is pale blue, marbled with pinkish or purplish white and olivaceous- brown, under a light brown, thin epidermis, everywhere encircled by close-set narrow brown lines, which are usually broken up into brown and white articulations.
|
|
The size of the shell varies between 22 mm and 50 mm. (Original description by W.H. Dall) The shell is biconic, solid, with a low, slightly turreted spire, straight sides and about ten whorls. The surface of the whorls on the spire are evenly excavated, smooth, or with two or three faint spiral striae in the channel. The periostracum is dense, brown, and velvety, except where cleaned off, when the substratum, which is very adherent, may appear polished.
|
|
The average angular deviation is insignificant when compared with the total of instrumental (measuring tools) and observation (unevenness of fault surfaces and striae) errors in majority of the cases. In conclusion, the reduced stress tensor method is validated when # sample size is large and representative (homogeneous data sets with a range of fault orientations), # sense of motion of is noted, # minimization of angular difference is emphasized when choosing functions (mentioned in section above), and # rigorous computation takes place.
|
|
The whole base is covered with rather regular, riblike striae and very fine microscopic ones, visible also on the upper part of the shell. The large umbilicus occupies from the base of the columella to the opposite side, about 2/5 of the diameter of the shell It is funnel-shaped, and pervious. Its wall is spirally striate, with a single, spiral, beaded rib and radiating plicae. The thin aperture is rhombic, probably not quite developed.

The lower sandstones of this sequence have characteristics similar to the Furnas Formation of São Paulo in Brazil.Harrington, Horacio J. Uruguay - Handbook of South American Geology. 1956. During the Late Paleozoic the territory of Uruguay was affected by the Karoo Glaciation and was subsequently covered by ice lobes of the great ice sheet that covered large parts of Gondwana. Glacial striae on shales and varve-like sediments found in Uruguay have been associated with this glaciation.
|
|
The color pattern of the first whorl is white the remainder brownish-red, streaked with white, ornamented with a zone of chestnut interrupted with white above. They are spirally lirate, and elegantly clathrate with lamellose radiating striae. There are four spiral cinguli on the penultimate whorl. The convex body whorl is elongated, with a zone of white and chestnut spots at the periphery, convex beneath, whitish or maculate with chestnut, clathrate, with about 4 concentric lirae.

Synthetic rubies may have no imperfections visible to the naked eye but magnification may reveal curved striae and gas bubbles. The fewer the number and the less obvious the imperfections, the more valuable the ruby is; unless there are no imperfections (i.e., a perfect ruby), in which case it will be suspected of being artificial. Dopants are added to some manufactured rubies so they can be identified as synthetic, but most need gemological testing to determine their origin.

Buphthalmos in itself is merely a clinical sign and does not generate symptoms. Patients with glaucoma often initially have no symptoms; later, they can exhibit excessive tearing (lacrimation) and extreme sensitivity to light (photophobia). On ophthalmologic exam, a doctor can detect increased intraocular pressure, distortion of the optic disc, and corneal edema, which manifests as haziness. Other symptoms include a prominent eyeball, Haab's striae tear in the Descemet's membrane of the cornea, an enlarged cornea, and myopia.
|
|
The length of the shell attains 13 mm, its diameter 5.5 mm. The small shell is fusiform and rather solid. The sculpture consists of 11 to 12 low, strong, rounded, and slightly oblique axial ribs, rather wider than the interspaces, obsolete on the base and usually on approaching the outer lip. The spiral sculpture consists of minute striae, erased upon the ribs, a few at the anterior end stronger, and frequently several rough irregular ridges on the basal fascicle.
|
|
The elytra have nine weakly impressed punctate striae and are broadly rounded at the posterior. The hind wings are as long as they are wide and have oblique, apically dividing, linear sclerites. The male beetle is smaller than the female and is much the same width for most of its length whereas the female is broadest in the posterior third of its length.Brachypsectridae The larva is pale coloured, up to fifteen millimetres long, flattened and broadly ovate.
|
|
It has a very peculiar sculpture. Under the rather elevated slit fasciole there are two elevated lirae, and the base has concentric lirae and grooves, while the usual growth striae are not lacking. In the example figured in the "Description of Egypt" there is a deep groove between the keel and the upper of the two spiral lirae. In the examples observed by me (= W.H. Dall) the groove is very shallow, and bears an elevated line.
|
|
Hindwing greyish brown irrorated (sprinkled) with minute dark spots and short transverse striae, and shaded in the cell, on the middle of the costal margin, and on the middle of the termen with diffuse brown. Antennae, head, thorax and abdomen dark brown; beneath, palpi, thorax and abdomen greyish brown. The larger varieties, with very broad orange markings on both forewings and hindwings, have been separated as race sanguinalis. This is chiefly a Himalayan and eastern form.
|
|
Some shells have transverse striae, others are smooth. As with earlier actinocerids, Rayonnoceras has a canal system within the siphuncle that includes a narrow opening, the parispatium, between the internal deposits and inner wall of the connecting ring. It differs from the earlier actinocerids in having a bullet- like apex with a cicatrix and a long first chamber, characteristic of pseuorthocerids, rather than a blunt apex and short first chamber characteristic of true actinocerids. Orientation during life was horizontal.
|
|
Tooth in matrix The type specimen preserves seven teeth in various degrees of preservation which increase in size in an anteroposterior direction, except for the last tooth which is slightly smaller than the penultimate of the preserved teeth. The teeth are straight, broad cones with rounded and domed tips. In cross-section the teeth are subcircular. Tooth crowns possess unwaisted bases and are covered in fine parallel ribbing or striae, numbering at approximately 65 to 70 per tooth.
|
|
The height of the shell attains 6½ mm. The dull white, imperforate shell has an ovate-conic, subventricose shape. The apex is rather obtuse. The shell is ornamented with strong spiral subnodose ribs, decussated by elevated rib-striae cutting the interstices into square pits, of which there are 3 or 4 series on the third whorl, 4 on the penultimate, and 7 on the last ; The five, rounded whorls are separated by a deep, subcanaliculate suture.
|
|
Between the borders of the striae and skin, there are curled, broken, reticular elastic fibres sometimes present. These symptoms are responsible for cobweblike skin appearances in patients with MFS. Management of MFS is to operate on the individual through open heart surgery. Management of MFS includes standard implications such as counselling on lifestyle to reduce and restrict physical activity, endo prophylaxis, serial imaging the aorta, ß-blocker medication for aortic protection and prophylactic replacement of the aortic root.
|
|
The axial sculpture consists of many protractively flexuous extremely fine lines with wider interspaces over all the whorls. The cemented edges at the suture by their opacity look like a presutural band, but this is not reflected in the sculpture. The spiral sculpture on the spire consists of almost microscopic close striae. On the base there are about a dozen fine spiral grooves between the edge of the umbilicus and the periphery, a little coarser near the carina.
|
|
These riblets then suddenly disappear, only very fine striae succeeding them, being scarcely perceptible on the body whorl, which is bicarinate. A third keel borders the flattened base;. The suture is rather conspicuous but shallow, with very slight traces of being margined, probably by the covered keel. The base of the shell shows 7 spirals of which the distal one, separated from the third keel by a slightly concave space, and one bordering the umbilicus are stronger.

84 The youngest rocks are diatremes, referring to breccia-filled volcanic pipes that were formed by gaseous explosions. They occur as dikes or sills which criss-cross the all older rocks types. Also located in the islands are good examples of shatter cones, rare geological features formed in bedrock by the high velocity shock waves created by meteorite impacts. They have a distinctively conical shape with thin grooves (striae) that radiate from the top (apex) of the cone.
|
|
Upon the base of the body whorl the ridges become broader and broader. In the vicinity of the umbilicus they exceed double the breadth of the intervening furrows. The layer which this sculpture principally composes, is for the rest only about the thickness of a coat of varnish. And beneath it, it is showing very slight traces of longitudinal striae, appears silvery mother-of-pearl, which shines on the whorls of many specimens while still living.
|
|
When the technique is used for wall glazing, the entire surface is covered, often showing traces of texture (French brush, parchment, striae, rag rolling). Either oil-based or water-based materials are used for glazing walls, depending upon the desired effect. Kerosene or linseed oil may be used to extend the "open" or working time of oil-based glazes. Water-based glazes are sometimes thinned with glycerin or another wetting agent to extend the working time.
|
|
The forewings are rufous fawn with a few brown striae. The lines are dark brown, the first from the costa shortly before the middle, acutely angled close to the costa, then oblique to near the base of the inner margin. The second from just beyond the middle, running obliquely outwards, with two bright brown velvety blotches on it, acutely angled outwards and incurved to near the middle of the inner margin. There is a minute white cell-dot.
|
|
There is a fuscous mark below vein two, as well as some white points on the costa towards the apex. The subterminal line is slight, grey defined on the inner side by black striae, excurved at the middle, and angled inwards at the discal and submedian folds. There is a fine waved black terminal line with an ochreous-white mark before it below vein three and a black-brown spot below vein two. The hindwings are fuscous brown.
|
|
The third dorsal striae is broader and more distinct. The dorsal margin has a broad white band extending from the base to the tornal area and there is a narrow silvery-white fascia with metallic reflection from the costal six-seventh to the dorsal margin. The distal one-seventh is yellowish brown, with a central black dot and with a triangular white dot near the costa and a white streak along the dorsal margin. The hindwings are greyish brown.
|
|
Epicephala camurella is a moth of the family Gracillariidae. It is found in China (Hainan). The length of the forewings is 7−10 mm. The forewings are greyish brown to brown, sometimes tinged with ochreous scales and with three pairs of white striae from both the costal and dorsal margins at one-third, three-fifths and four-fifths, extending obliquely outward to the middle and end of the cell as well as to outside of the cell.
|
|
The inner lip has a thin, complete glaze. The base of the shell is roundly concave. The columella is straight, curved to the left in the siphonal canal, and slightly thickened on the outside of its anterior end. The narrow spiral cords, one-third as wide as their interspaces, increase from four in the first whorl to nine in the penultimate whorl, and twenty-three in the body whorl, and are minutely roughened by sublenticular accremental striae.

|
In the medulla oblongata, the arcuate nucleus is a group of neurons located on the anterior surface of the medullary pyramids. These nuclei are the extension of the pontine nuclei. They receive fibers from the corticospinal tract and send their axons through the anterior external arcuate fibers and medullary striae to the cerebellum via the inferior cerebellar peduncle. Arcuate nuclei are capable of chemosensitivity and have a proven role in the respiratory center controlling the breathing rate.
|
|
Epicephala tertiaria is a moth of the family Gracillariidae first described by Hou-Hun Li in 2015. It is found in the Chinese provinces of Guangdong and Guangxi. The length of the forewings is 6−8.5 mm. The wings are brown to dark brown, the forewings with three pairs of white striae from both the costal and dorsal , and extending obliquely outward to the middle and end of the cell as well as outside of the cell respectively.

Male upperside dark Vandyke brown; costa preapically, lower half of termen on forewing narrowly and termen of hindwing more broadly bluish grey, crossed by the dark veins and touched with brown at the apices of the latter; forewing with a preapical black spot pupilled with white, another plain black spot in interspace 2, and two intermediate white dots; hindwing with a subanal white-centred black spot. Underside pale sepia brown, irrorated with numerous white striae, the discal and tornal area only of the forewing without striae; both wings crossed by a highly sinuous, broad, white discal band, inwardly defined by a dark brown line, subterminal and terminal narrow brown bands; the round black spots as on the upperside, but more distinct and ringed with yellow; hindwing with an additional ocellus in interspace 5. Antennae, head, thorax and abdomen concolorous with the wings above, paler below. Sex-mark a large dark brown patch of specialized scales on basal half of forewing, Female: Similar, the greyish-white marginal borders broader.
|
|
The forewings are orange yellow with slight subbasal brownish spots in the cell and above the inner margin. The costa is brownish to the excurved dark antemedial line, which is incurved and obsolescent at vein 1. There is a black discoidal lunule and a postmedial line formed of small fuscous spots in and on the interspaces, arising below the costa, incurved at vein 7, excurved to vein 2, then bent inwards. There is a series of dark striae just before the termen.
|
|
The spiral sculpture consists of fine flattish threads separated by narrow striae very minutely reticulated by the incremental lines and most conspicuous in the intervals between the ribs, practically covering the whole surface of the shell. The axial sculpture, beside almost microscopic lines of growth, consists of (on the body whorl 14) short rounded ribs, slightly angulated at the shoulder and extending from the suture to the siphonal canal with subequal interspaces. The anal sulcus is shallow. The aperture is narrow and simple.
|
|
The apex is defective. The subsequent whorls are rather rapidly increasing, with an appressed suture behind a smooth and constricted anal fasciole. In front of which the shell is shouldered by a series of short, slightly protective ribs, of which, on the penultimate whorl there are fifteen, with subequal interspaces and crossed by half a dozen irregularly spaced spiral striations. These striae are ill-defined, and on the body whorl extend over the base of the shell to the siphonal canal.
|
|
The shell size varies between 25 mm and 50 mm The ovate, conical shell is of a reddish or olive color. It is composed of eight or nine whorls, the lowest of which composes nearly half of the shell. It is smooth, slightly arcuated, and often ornamented upon each whorl with a whitish band. When young, it is marked with convex, longitudinal folds, which are intersected at the base of the body whorl only, by five or six pretty deep transverse striae.
|
|
The outer lip has a slight obliquity, relatively to the axis of the shell. It is slightly crenulated upon the lip, and furnished interiorly with fifteen or sixteen transverse striae which are continued even to the depth of the cavity. The emargination is very oblique, accompanied externally by a thick, rounded, and twisted varix, which, revolving around the axis, terminates below the folds of the columella. This is slightly arcuated; one or two oblique folds are delineated at its base.
|
|
The size of the whitish, solid shell varies between 11 mm and 14 mm. The protoconch is paucispiral with a slightly less than one whorl and shows fine spiral striae (stretch marks). The teleoconch consists of 3.5 whorls with the second and the third whorl showing five spiral bands and the body whorl with twelve spiral bands. The whorls are axially crossed by twelve and thirteen rounded ribs on the second and third whorls and by ten ribs on the body whorl.

Closeup of cap surface revealing gradual differences in squamule structure and pigmentation progressing from the center of cap (top) to the margin The spores are olivaceous-brown in medium to heavy deposit. They are inamyloid, almond-shaped, contain one or more oil droplets, and measure 17.5–22.2 by 6.4-8 µm. The spore wall is 0.5–1 µm thick, with 12–14 longitudinal ridges. These ridges are less than 1 µm tall, occasionally bifurcating, converging at poles, with minute cross-striae.
|
|
Although these cross-striae are visible when observed with light microscopy, they are not evident when viewed with scanning electron microscopy. The hilar appendage (the region of a spore which attaches to the basidium via the sterigma) is 0.3–1 µm long. The basidia are four-spored, club-shaped, and have numerous refractive globules; they measure 39–57 by 11–15 µm. The pleurocystidia (cystidia on the face of a gill) are 42–47 by 8-12 µm, swollen and beaked, slightly capitate.
|
|
The about six whorls are somewhat convex. The upper surface of each whorl shows usually four or five spiral closely granose lirae, in the interstices between which sharp microscopic oblique and spiral striae are visible under a lens. The body whorl is carinated at the periphery, usually with six lirae on the upper surface, convex beneath, concentrically lirate, the lime very narrow, feebly granose or nearly smooth, separated by wide lightly obliquely striate interspaces, the inner lirae closer. The aperture is rhomboidal.

Vitamin A, also known as retinoids, benefits the skin by normalizing keratinization, downregulating sebum production which contributes to acne, and reversing and treating photodamage, striae, and cellulite. Vitamin D and analogues are used to downregulate the cutaneous immune system and epithelial proliferation while promoting differentiation. Vitamin C is an antioxidant that regulates collagen synthesis, forms barrier lipids, regenerates vitamin E, and provides photoprotection. Vitamin E is a membrane antioxidant that protects against oxidative damage and also provides protection against harmful UV rays.

The size of the shell attains 8 mm. The shell consists of the protoconch nucleus plus 4 whorls. The profile is rather strongly convex in the upper half of the whorl. There are spiral lirae 2 on 2nd and 3rd whorls, 3 on 4th whorl. These are broad and low, scarcely projecting above the profile, defined by impressed striae, the 3rd being peripheral and feebly carinate; an additional stria (or 2) between 1st and 2nd lirae, and 2-3 between 2nd and 3rd.

During the Llanquihue glaciation volcanism occurred on all three vents, Cordillera Nevada, Cordón Caulle and Puyehue volcano. During most of this time the volcano was covered by the Patagonian Ice Sheet, leaving glacial striae on many lava outcrops and affecting the volcanic activity. In Cordillera Nevada this volcanism was expressed from about 117,000 years ago primarily as dacitic lava flows erupted along ring faults. These lava flows partly filled the caldera and flowed north, out to what is now Nilahue River.

In 1895, Wickham further explained the characteristic of the lesion, now known as Wickham striae. Further on, Darier explained the presence of such characteristic markings by correlating with an increase thickness of the granular cell layer. The coexistence of oral, cervical and stomach lichen planus lesions were described by Guogerot and Burnier in 1937. A similar variant of mucosal lichen planus as the vulvovaginal-gingival syndrome with erosive lesions involving oral and vulvovaginal mucosa were introduced by Pelisse and colleagues in year 1982.

Upperside dark brown. Forewing: a medial dull whitish spot at base of interspace 3 extended upwards on to vein 4 and below into interspace 2. Hindwing; uniform, immaculate. Underside: very pale dull brown, with darker brown mottlings and striae, that on the forewing are absent on a broad streak from base outwards along the basal half of the dorsum, this area pale brown without markings; a dark obscure spot at apex of cell and an incomplete similarly obscure dark transverse discal band.

The Norwegian wasp is classified under the family Vespidae and the genus Dolichovespula. Based on recent studies on mitochondria genes, Dolichovespula and Vespula are monophyletic, meaning they descended from common ancestors. Two species groups, maculata and norwegica form the Dolichovespula clade. While the maculata has physical attributes such as pronotal striae, emarginate apex of the seventh metasomal sternum in males, and aedeagal medial lobes, D. norwegica females have long oculo-malar space and lateroanterior clypeal angles with less prominent semicircular projections.

The most common skin manifestation of MFS is striae distensae where bands of skin are coloured red, purple and then white. The skin epidermis is thin and flattened, and the upper protective skin layer is decreased in thickness. This manifestation is characterised histologically by straight, thin collagen bundles arranged in a parallel to the skin and the elastic fibres. Elastic fibres are denser in the upper dermis, and beneath this zone there is a localised absence of the elastic fibres.

Wet-season form. Male and female: Forewing: costa strongly arched, apex acute; termen immediately below apex in male angulate, in female falcate (sickle shaped). Upperside resembles M. ismene, but ground colour on the whole somewhat warmer brown, a very broad patch of ochraceous yellow, above and beyond the subapical black spots, larger in the female than in the male. Underside closely irrorated (sprinkled) with dark brown striae (lines); the ocelli subequal, very much smaller and less clearly defined than in M. ismene.

The other species was named C. cassandrae, characterized by its elliptically shaped valve paired with its coarse striae. Most notably it has a scattered ring of central fultoportulae (21). Discovering fossils is not often a credible enough way to determine a new species within the phylum of diatoms, given that determining underlying mechanisms based on morphological variability is unreliable. It's best to use both morphological and paleoecological data obtained from samples- the two are often difficult to obtain just from fossils (20).
|
|
The 9 remaining whorls are divided in 2 parts, of which the upper part is excavated, slightly convex in itself in last 2 whorls. The lower part of each whorl shows rounded, oblique axial ribs, disappearing on the body whorl, where there are only traces on ventral side. These ribs number eleven on penultimate whorl. The finer sculpture consists of fine and coarse growth striae and spiral ones, stronger below the suture, across the convex ribbed part, fainter near the base.

Epicephala impolliniferens is a moth of the family Gracillariidae. It is found in China (Hainan). The length of the forewings is 7−10.5 mm. The forewings are brown to dark brown with three pairs of white striae from both the costal and dorsal margins at two-fifths, two-thirds and three-fourths, extending obliquely outward to the middle as well as to the end and outside of the cell, the second dorsal stria is longest and the third costal stria is shortest.
|
|
The sculpture consists of this spiral and some other ones, 7in number on penultimate, 22 and a few intermediate ones on last whorl, stronger on lower part of upper whorls and on median part of last one. The spirals are crossed by conspicuous growth- striae, stronger in the interstices, which are broader near the base. The aperture is oval and angular above. The peristome is strong, with a rather wide, deep sinus above, protracted lower on, bordered exteriorly by a strong, rounded rib.
|
|
The subspecific name altoensis refers to El Alto, the type locality. Scutalus phaeocheilus altoensis is characterized by the whitish colour, the sculpture of growth striae and inconspicuous granules on the last whorl, the broadly expanded lip and the orange colour of the aperture inside. The height of the shell is up to 38.1 mm, 1.71 times as long as wide, deeply perforated, conical, with slightly convex sides and solid. Colour is uniformly (greyish-)whitish, the upper whorls somewhat lighter in greyish-white specimens.
|
|
Another deep blue angulated line passes around the costal blotch and terminates in the subapical spot. There is a small whitish wedge-shaped spot edged dark fuscous on the subapical sinuation and there are two dark fuscous striae (stripes) confluent into a spot above from before the apex of this spot to the tornus, as well as two round blackish dots before the termen about the middle. The hindwings are fulvous (tawny coloured), beyond a curved dark fuscous subterminal streak reddish- orange.Exotic Microlep.

The cephalothorax of Ethusa mascarone is almost rectangular, it can reach a length of and a width of . The body color is gray- brown, with brown lines on the carapace and transverse striae on the abdomen. Chelipeds and legs are lighter and white speckled.Tegnue.chioggia The front pairs of legs are long, but the hind legs are shorter and are used to carry on the back a variety of objects and organisms, especially valves of bivalves, by which these crabs camouflage and protect themselves.

In pregnancy they usually form during the last trimester, and usually on the belly, but also commonly occur on the breasts, thighs, hips, lower back and buttocks; these are known as striae gravidarum. Stretch marks may also be influenced by the hormonal changes associated with puberty, pregnancy, bodybuilding, or hormone replacement therapy. There is no evidence that creams used during pregnancy prevent stretch marks. Once they have formed there is no clearly effective treatment, though various methods have been attempted and studied.

|
It contains about 8 whorls, of which nearly 2 smooth ones form the protoconch, . The subsequent whorls are only very slightly convex, separated by a rather conspicuous suture, which is however not very distinct by the spiral grooves, with which the whole shell is encircled. These grooves are rather deep, the subsutural and median one of body whorl however less so. The lirae are granose on 2 or 3 postnuclear whorls, lower on they are only closely punctured, the lirae remaining smooth, but for fine growth striae.
|
|
The sculpture consists of remote, oblique, axial ribs, conspicuous in the upper whorls, fainter lower on, disappearing on the back of the body whorl. They form tubercles below the excavation, which in the upper whorls bear short plicae, just below the suture. The lower part of the whorls is crossed by very numerous spiral striae, conspicuous in upper whorls, faint on the last one, but stronger towards and on the siphonal canal. The aperture is elongately-oval, angular above, with a wide siphonal canal below.
|
|
The whorls show an angle at the shoulder where terminate (on the penultimate whorl twenty) straight, somewhat protractive, low, narrow, rather sharp axial ribs. These extend forward on the body whorl nearly to the base. Incremental lines are rather prominent. The spiral sculpture consists of a few faint striae on the fasciole, between the fasciole and the next suture on the spire of five or six strap-like ridges with narrower interspaces often containing an obscure small intercalary thread, overriding the ribs without nodulation at the intersections.
|
|
This lower part has rather inconspicuous axial ribs, nearly disappearing in the body whorl and tubercled at the angle below the excavation. Otherwise the axial sculpture consists of rather strong, nearly riblike, much curved, raised striae in the excavation and very fine growth-lines. Of spirals there are 4 on penultimate whorl, below and besides that accompanying the peripheral angle, and numerous spirals on body whorl, with eventually intermediate ones. Moreover the shell is covered with excessively small granules, only visible under a strong lens.
|
|
The incremental sculpture is faint. The spiral sculpture begins on the early whorls with about four faint striae which grow sharper on the later whorls which carry four or five grooves with wider flattish interspaces between the periphery and the succeeding suture, with on the later whorls sometimes one or two on the anal fasciole. On the body whorl there are 16 or more in all. The last rib on the body whorl is more swollen than the others and usually darker in color.
|
|
The shell size varies between 18 mm and 40 mm The ovate, ventricose shell is pretty thick. It is composed of six or seven flattened whorls, angular above, and the lowest of which forms of itself half the shell. This body whorl is very much inflated, and furnished externally with thick, longitudinal, distant folds, which are intersected by transverse striae. The upper extremity of each fold is terminated by a conical tubercle, sometimes separated from it by a transverse stria which divides it superficially into two.
|
|
The shell is of a variable color, bluish ash, reddish or brown, covered with narrow, white, longitudinal lines, irregularly spread over it. A deeper zone surrounds the suture, and two or three others are found upon the body whorl, that of the middle much more marked, and sometimes the only one. The spire is composed of six convex whorls, slightly flattened at their upper part, and crowned by a row of rounded tubercles. The three or four upper whorls are folded longitudinally, and intersected by transverse striae.
|
|
The forewings are sap-green, slightly irrorated with black, some deep rufous and blackish suffusion below and beyond end of cell and at the base of the inner margin. There is a diffused blackish subbasal line. The antemedial line is black, oblique and slightly sinuous and the terminal half of the costa has black striae with pale brown between them. The postmedial line is white, defined on the inner and outer sides by a series of black points, slightly excurved below the costa and at the middle.

Aepus marinus is a very small beetle, with adults reaching a length of about . The head is relatively large while the thorax is rather small and shaped like an isosceles triangle, with the base at the front and the apex at the rear. There is a deep furrow in the centre of the dorsal surface of the thorax. The elytra are narrowed at the front and shorter than the abdomen, and are sculptured with indistinct short striae (narrow grooves or channels) and puncture marks.

There are strong linear features on the right margin of the Esmeralda and Sinú Rivers; these include fault saddles and slight slope changes in alluvial terraces. Tertiary rock units are thrust over Quaternary deposits and striae are found on the shear planes. The fault is probably active with three earthquakes occurring in the twentieth century in the vicinity of the fault, February 12, 1952 (MW 6.7), December 3, 1970 (MW 5.7) and August 31, 1977 (MW 5.7). The slip rate is estimated at per year.

Male sex-mark in form 2. Dry-season form. Upperside similar but paler; the ocelli, especially on the hindwing, obscure or absent; the transverse white discal band on the wings seen by transmission from the underside narrow and very obscure. Underside: basal areas of wings up to the discal white band dark brown in the male, ochraceous brown in the female; the discal white band very narrow and ochraceous white; the terminal margins beyond purpurescent; ocelli minute; both forewings and hindwings irrorated with short, transverse, brown striae.
|
|
The forewing beneath is marked as above, the border of the brown central area is somewhat broader, the apex and distal margin densely dusted with bluish grey. The hindwing beneath dark brown from the base to the middle and thinly dusted with whitish grey, the outer half being blue-grey with small dark brown striae. At the apex of the cell there is an oval whitish grey spot and at the costal margin 2—3 somewhat smaller ones. — Central and Eastern Siberia (Amurland); besides in Arctic America.
|
|
The forewings are pale grey to greyish plumbeous, with both antemedian and postmedian areas diffusely suffused with pale rufous. The basal area is pale grey, sparsely frosted with whitish scales and there is a thick black line at the base, with black striae on the subcosta and on the submedian fold. The subbasal line is double, black and filled in with white. The inner line is conspicuous, while the outer line is somewhat diffuse and outwardly oblique from the costa to the median nervure.
|
|
The nucleus is smooth, followed by a 2nd and 3rd whorl, each with 6 spiral lirae of which the upper ones are slightly undulate. On the fourth whorl the lirae disappear, only the 'upper one remains and becomes beaded. It borders the broadly canaliculated suture, which in this and in the fifth whorl, is crossed by conspicuous striae, which run partly also on the convex, smooth, lower part of these whorls. Near the body whorl the beads disappear, the suture becomes less broad and deep.

The scientific name Turbo cornutus, literally means "horned turban," and it is characterized by a hard, ventricose, spiny, imperforate shell of which the length varies between 65 mm and 120 mm. It has a large, thick, green-gray shell with irregular incremental striae and spiral lirae. The shell has about 5-6 whorls, which turn clockwise and have horny protuberances. The body whorl is ventricose, somewhat bicarinate, armed about the middle with two spiral series of erect tubular spines, and frequently a smaller accessory row above.
|
|
The base between is flat and rounded, marked by evanescent (partly brown) grooves and transversely by delicate flexuous slightly raised aggregations of the lines of growth at somewhat regular intervals. These slightly crenate the umbilical rib on its inner edge and perhaps form the pronounced, slightly backwardly flexed, striae and ridges which mark the umbilical walls. There is hardly any callus on the body wall at the aperture, which is broken in the specimens at hand. Its form has been made out from the lines of growth.

|
Lichen planus affecting the lower lip Although lichen planus can present with a variety of lesions, the most common presentation is as a well defined area of purple-coloured, itchy, flat-topped papules with interspersed lacy white lines (Wickham's striae). This description is known as the characteristic "6 Ps" of lichen planus: planar (flat-topped), purple, polygonal, pruritic, papules, and plaques. This rash, after regressing, is likely to leave an area of hyperpigmentation that slowly fades. That said, a variety of other lesions can also occur.
|
|
The length of the holotype attains (the early whorls lost) 26.5 mm, its diameter 8.3 mm; whorls remaining. (Original description) This species is very similar to Carinodrillia elocata, but it is more slender with a longer anterior canal and a deeper posterior sinus. The anal fasciole and the spaces between the spiral ridges are distinctly striate spirally, with in each interval about 6 striae. There are seven broad, rounded axial folds on the penultimate whorl and on the body whorl, weakening on the anal fasciole.
|
|
It is rather small and slightly elongated. The whorls of the spire are distinct and mucronated (= ending in an abruptly tapering point). The body whorl has eleven or twelve narrow and slightly elevated longitudinal ribs, the surface of which, of a yellow ground, is crossed transversely by a great number of very fine blackish lines, which approach alternately, two by two. The intervals of the ribs are marked with very thin and delicate longitudinal striae, and with brown and whitish lines undulating in bars.
|
|
The colour of the shell is very variable: entire maroon or entire slate or either with broad radiating stripes of buff, or the spiials articulated with buff on a maroon or slate ground, or combinations of these. The nacre of the interior of the aperture is bordered with emerald. Sculpture: the shell contains elevated spiral ridges, four or five on the upper whorls, about sixteen on the last, andsmaller and closer on the base. Both ridges and interstices are obliquely crossed by fine growth striae.
|
|
These sometimes coalesce from above and below, thus replacing spiral by radial painting. The radial ribs are well developed, projecting as an angle on the shoulder, continuing from suture to base, and amounting to ten on the body whorl. The spiral threads are sharp on the upper whorls, where they are decussated by radial striae. Gradually they vanish, till on the middle of the body whorl the surface seems smooth to the eye, and only a few engraved spirals can be found with a lens.
|
|
They are ventricose, with delicate, highly elevated spiral rib-striae,- of which there are about 5 on the upper and 10 on the last whorl. The surface of the ribs is slightly tuberculous, and the last one overhangs the succeeding whorl so as to form a broad deep channel at the suture. The interspaces have about the same width as the ribs, and are beautifully barred with close-set laminae. The base of the shell isconvex, with a small deep scalariform umbilicus, sculptured like the spire.
|
|
The margin is separated from the central part by a deep groove, with about 7 spirals and faint growth striae. The umbilicus is large, pervious, scalar, and bordered by a strong rib which is surrounded by a deep groove, The umbilical wall is perpendicular. The aperture is rhombic, with convex upper, outer and basal margins. The keel is protracted in a claw in the younger specimen The columellar margin is excavated, slightly thickened, angular below near the umbilical keel, and forming there a somewhat tongue- shaped triangle.
|
|
The straight line only interrupted by a row of short, fold- like, oblique tubercles at the lower part of the whorls, somewhat fainter near the aperture. They number 17 on the penultimate whorl. The whorls have a second row of slightly oblong, bead-like tubercles, just below the suture, about 30 in number on the body whorl. The spiral sculpture consists of impressed striae, crossing the lower half of basal row of tubercles on each whorl, and 2 or 3 just above the suture.
|
|
Of these the upper 2 are smooth, the rest with crowded axial ribs. The post-nuclear whorls show more remote ribs, 7 or 8 on penultimate whorl, each rib with a small point near its middle, giving an angular appearance to these whorls, though the interstices are nearly regularly rounded. The upper part of the whorls are very faintly crenulate. The base of the body whorl shows very faint spiral striae, more conspicuous on the ribs and a few stronger ones on the sipgonal canal.

Due to the chronic and lengthy nature of some steroid responsive dermatoses such as atopic dermatitis and psoriasis, a study of 27 patients was conducted, wherein these patients were treated with Cloderm from 30 days up to 7 months. The results of these treatments showed a low rate of adverse reactions and no signs of striae, atrophy, or hypopigmentation. Adverse reactions that were experienced included burning, itching, irritation, dryness, and/or folliculitis. Additionally, a clinical study investigated the potential of hypothalamic–pituitary–adrenal (HPA) axis suppression.
|
|
The surface is lustreless, with incrassate growth striae and inconspicuous granulation, under a strong lens visible as spiral rows of shallowly raised, short oblong granules; only in fresh specimens this granulation may be observed on the third and following whorls. Protoconch is pit-reticulate. The shell has 5.7-6 whorls, that are somewhat convex. Suture is impressed, crenulated, at the aperture ascending in front. Aperture is large, ovate, in fresh shells orange inside; margins converging; 1.33 times as long as wide, 0.73 times the total height.

|
Consequently, the line of Retzius appears broader and much more prominent, often presenting a brownish colour under the microscope. The neonatal line is the darkest band, which represents the disrupted enamel formation due to the stress of being born. It is also said to occur due to periodic bending of enamel rods. The formation of the striae of Retzius results from a constriction of Tomes' processes when the activity of ameloblasts – cells only present in laying down enamel – is narrowed in conjunction with an increasing process of interrod enamel development.
|
|
A very few prominent, narrow, straight ribs (six on the body whorl) cross the whorls from suture to suture, separated by very wide, concave interspaces. A single rounded thread revolves on the periphery at the shoulder of the whorls, scarcely visible on the interspaces, but forming conspicuous, oblong nodules on the ribs. On the body whorl the ribs continue to the end of the siphonal canal curving in from its base, towards the aperture. On the ventral surface of the siphonal canal there are five or six very indistinct, oblique striae.
|
|
The post- nuclear whorls are sharply angular. Their upper part is slightly concave and occupies about ⅔ of each whorl,. The sculpture consists of numerous, sharp axial ribs, 16 in number on the body whorl, with pointed tubercles at the angle, connected by a rather faint spiral..Moreover, there are very faint growth lines and spiral striae, more conspicuous on the base of the body whorl, especially on the ribs, and a few stronger ones on the siphonal canal. The aperture is oval, angular above, with a short, broad siphonal canal below.
|
|
Microscopic striae intersect the fine lines of growth, giving to the entire surface of the shell a peculiar crinkled appearance. The protoconch is broad, blunt, smooth, somewhat shining, consisting of two and a half whorls. The apical whorl is large, rising very little above the succeeding one. Bush, K.J. (1893) Reports on the results of dredging, under the supervision of Alexander Agassiz, in the Gulf of Mexico (1877–1878), and in the Caribbean Sea (1879–80), and along the Atlantic Coast of the United States (1880), by the U. S. Coast Survey Steamer “Blake”, Lieut.

In the past during the Late Quaternary, the mountain was more extensively glaciated, with about nine glaciers surrounding it including a subsidiary summit to the south. Former glaciers did reach lengths of and their tongues descended to elevations of on the northern, eastern and southern flanks; they have left well developed glacial striae, glacial valleys and various types of moraines. The lowest moraines are found on the eastern flank, with the northern flanks having the highest moraines and the southern flank moraines reaching intermediate elevations. Some ancient tills have been overrun by porphyries.
|
|
The subsequent whorls are convex, separated by a linear suture, with a slight excavation below it. The sculpture consists of remote, rounded ribs, 10 in number on penultimate whorl, stronger on the upper ones, and numerous, raised, axial striae, as well on the ribs as in the interstices. This sculpture is crossed by numerous spiral lirae, which are fainter in the excavation and of which some, (4 on penultimate whorl) are stronger. In crossing the ribs these stronger lirae produce tubercles, strongest on upper whorls, nearly disappearing on the body whorl.
|
|
The columella is straight, forming an obtuse angle with the inner lip, which is distinct, complete, applied, and glazed. The outer lip has a finely crenulated border. In profile retrocurrent at the suture to form a shallow sinus, then uniformly curved, convex, with a shallow excavation at the contracted base. The whole surface of the shell is sculptured with spiral lirae, six in the first whorl, twelve in the second, sixteen in the third, and fifty-two in the body whorl, granulated by very fine axial striae which granulate the sutural margin.
|
|
Other revolving sculpture consistis of microscopic striae covering the shell, which in favorable localities in crossing the lines of growth (as, for instance, on the notch-band) occasionally give rise to microscopic shagreening, invisible except in a good light and under a good lens. The transverse sculpture consists only of generally faint lines of growth, and the oblique nodosities above mentioned, which extend on the posterior whorls from the periphery to the suture, and on the body whorl are proportionally smaller. These vary from eleven to thirteen in number per whorl. The ; aperture is narrow.
|
|
The depression or concavity at the upper part of the whorls produces a marginate appearance at the suture, and upon the margination the lines of growth are slightly puckered. The spiral striae are somewhat deep and have rather a regular look to the naked eye. The nodose plications at the angulation above do not extend far downwards, but soon become obsolete, so that the lower part of the whorls has a nearly even surface. The white aperture is oblong and measures just under half the length of the shell.
|
|
The first two are most prominent, and angulate the riblets where they cross them, producing little raised points. The succeeding threads are a little enlarged where they cross the ribs, but do not form points, and are as usual closer together on the anterior part of the siphonal canal. On the band is no sculpture except the lines of growth and an occasional faint indication of revolving striae. The number of riblets and of threads with their respective sharpness and the prominence of the nodules are somewhat variable.
|
|
The length of the shell varies between 13 mm and 20 mm. The ovate, conical shell has an ash-gray color. It is ornamented with a reddish zone at the suture, and another, much wider and more deeply colored band, at the base of the body whorl. The spire is composed of seven rounded, swollen whorls, provided with ten or twelve distant and slightly oblique folds, marked also by a great number of transverse striae, which intersect the folds at right angles, and become more apparent near the base of the body whorl.
|
|
The size of an adult shell varies between 12 mm and 43 mm. The spire is more or less raised, striate or sometimes nearly smooth, with or without tubercles The body whorl is striate, the stride usually grannlous towards the base, and sometimes throughout. The color of the shell is yellowish or light chestnut or grayish, variously clouded with darker chestnut or olive, often irregularly light-banded at the middle, and below the spire, and encircled with chestnut spots on the striae. The interior is chocolate, with a central white band.
|
|
Below this spiral remains a rather large groove. The basal part of the whorls show narrow, a little oblique ribs, 15 in number on the body whorl, ending below the groove in short tubercles, which are connected by a second spiral. The space between the ribs is sculptured by fine and coarse growth-lines and faint spiral striae, becoming stronger and groove-like towards the base of the body whorl, and have the character of lirae on the short, large siphonal canal. The body whorl is regularly convex, until the siphonal canal.

Krikken noted that the specimen was similar in appearance to the genus Giesbertiolus described in 1988 but slightly larger, with a body length of (other Giesbertiolus species are reported as being ). It has an almost complete set of punctate elytral striae and a slightly raised interstriae. The body and head are black and shiny with iridescent, greenish white markings and small punctures; the appendages on the head are brownish in colour. There is an abundance of fine pale yellow hair on the ventral side and some on the dorsal side.

Antenna, head, thorax and abdomen brown; antennae annulated (ringed) with white, ochraceous at apex. Male sex-mark in form 2. Mycalesis suaveolens Wood-Mason & de Nicéville, 1883 resembles M. mestra, but differs constantly as follows: Upperside ground colour a brighter, more ruddy brown; cilia white tinged with ochraceous; the discal, subterminal and terminal bands on the underside showing through much more faintly than in M. mestra; the number of ocelli very variable. Underside: basal area uniform, with no trace of the pale transverse striae; white discal band narrower, subterminal and terminal bands brownish white.
|
|
Ventral and umblical shoulders are sharp. The suture is with a shallow ventral lobe and broad lateral lobes with subacute saddles on the shoulders; the siphuncle is tubular, near the venter; the living chamber half a volution in length. The surface is covered with alternating striae and lirae; fine, parallel "scratches" and "wires" Strophiceras has a probably gyroconic shell with a higher than wide, compressed, subrectangular whorl section with slightly arched dorsum and venter and flattened flanks. The venter has a median ridge aligned with diagonally elongated nodes.
|
|
Underside pale brown. If ore wing: apex grey, irrorated with minute dark spots; cell with a broad dull orange streak from base, followed by a violescent transverse spot in apex of cell; a large discal dull violescent spot in interspace 2 spreading slightly into interspace 3,. the curved series of three preapical spots as on the upperside but faintly dull violescent. Hindwing greyish brown, irrorated with dark spots and transverse dark striae and shaded with darker brown; the medial dull orange band replaced by a similar pale well-marked baud.
|
|
Hindwing: dorsal margin dusky; terminal broadly, costal margin more narrowly, black; a subterminal series of four white spots. Underside tawny, with markings similar to those in the male; the pale whitish markings more extensive; the dorsal margin broadly without striae. Race fraterna, Butler (Sri Lanka) is an insular representative of E. undularis. The male differs on the upperside in the more or less complete absence of the subterminal and preapical blue markings on the forewing; and in the broad terminal border of the hindwing being of a much brighter, almost ochraceous chestnut.

Boletellus ananaeceps Strobilomyces strobilaceus is roughly similar in appearance because of its rough scaly cap and lacerated margin, but may be distinguished from B. ananas by smooth stem without a ring, different spores, and flesh that is less tough. The Australian species Boletellus ananaeceps has spores with narrow longitudinal ribs that do not have cross-striae. B. dissiliens has colors that are not red as in B. ananas, and pores that can become reddish in maturity. Further, the cap flesh of B. dissiliens turns blue upon exposure to air.

The periphery of the body whorl is sometimes articulated with white, and the base of the shell is either unicolored dark, or finely dotted with white. The shell contains 10 whorls, the apical one or two convex and smooth, the following flat, finely spirally striate (about 14 striae on the penultimate whorl of a large specimen). The body whorl is convex at the periphery, angulated there in specimens not completely adult, and convex beneath, with 10-12 concentric lirulae there. The entire surface contains fine lines of growth.

Museum specimen The pretty thick shell is ovate-globose and ventricose. The pointed spire is formed of six whorls, the upper of which are slightly convex, but little developed, having three or four transverse striae, very apparent, and spotted with brown blotches. The body whorl is very much inflated, completely surrounded by from fifteen to twenty equal ribs, depressed, but slightly rounded. These ribs are separated from each other by a shallow furrow, which becomes wider between the first two or three upper ribs, by the disappearance of the intermediate ribs.
|
|
The length of the shell varies attains 13 mm, its diameter 3.8 mm. (Original description) The elongate-fusiform shell approaches in form the European Mangelia attenuata (Montagu, 1803), but it is larger, the elongate spire proportionately longer, whilst the whorls are slightly shouldered. The transverse striae are very fine, and the longitudinal ribs regular and rounded. The colour is yellowish white, suffused with greyish green, with transverse lines of light brown, and a dark brown band, interrupted by the ribs, at the angle of the whorls, and another near the base of the body-whorl.

Leitz laboratories discovered that lanthanum(III) oxide can be a suitable thorium dioxide replacement. Other elements however had to be added to preserve the amorphous character of the glass and prevent crystallization that would cause striae defects. After 1930, George W. Morey introduced the lanthanum oxide and oxides of other rare-earth elements in borate glasses, greatly expanding the available range of high-index low-dispersion glasses. Borate glasses have lower wavelength-refraction dependence in the blue region of spectrum than silicate glasses with the same Abbe number.

Kionoceras is an extinct nautiloid cephalopod genus included in the orthocerid family Kionoceratidae with scattered worldwide distribution from the Middle Ordovician to the Lower Permian. Kionoceratids are orthocerids with prominent longitudinal ornamentation on their shells, sometimes augmented by secondary transverse ornamenttion. Orthocerids are, of course, prehistoric nautiloides with generally straight and elongate shells, mostly with central or subcentral siphuncles. (Sweet 1964) Kionoceras is characterized by long, slender to rapidly expanding, shells with prominent longitudinal ribs separated by concave interspaces and, often, less conspicuous longitudinal and transverse lirae and striae.

The dorsal fin begins on the anterior profile of the head, with 65-78 fin rays. The anal fin contains 49-63 fin rays, and the caudal fin is connected to the dorsal and anal fins by a small membrane. The pectoral fin on the eyed side is small, with 3-5 fin rays, and the one on the blind side is reduced to 1 long and 1-2 short fin rays. The lateral line scales number 55-70, and are rectangular in shape with short, strongly curved intercanalicular striae.
|
|
The spiral lirae increase in number, to about 10 weaker spirals on the upper part and 4 or 5 stronger ones at the lower part of the upper surface, and numerous intermediate ones. Below the rounded periphery appear two or three more remote lirae, with intermediate ones and numerous, regular, flatter lirae on the convex basal part, becoming broader towards the umbilicus. The whole shell is crossed by oblique, fine, but conspicuous growth-striae. The umbilicus is narrow, in the front view concealed by the columellar margin, with rather smooth walls.
|
|
Below these there is a minutely white-speckled belt, and then at the periphery a series of red spots. On the base of the shell, the umbilicus is fleshy-whitish; outside of this there is a red area closely mottled with opaque white; and between this tract and the periphery there is a pale zone, sometimes marked with distant radial series of two red dots each. The surface is smooth except at and above the periphery, where there are several spiral striae. The 5½ whorls are slightly convex, parted by an impressed suture.
|
|
The ornament of penultimate whorl consists of four equal and equidistant granulose lirae, and obliquely transverse raised threads. Of the body whorl, a small granulose lirais interposed between the third and fourth, anterior to the fourth are two smaller equally distant from one another, the fifth is slightly granulose, whilst the sixth, which is at the periphery, is broad and obtuse. The interspaces between the lirae are faintly spirally striate. The base has seven concentric lirae, the inner ones subgranose, the outer ones plain, with a few coincident striae in the interspaces.
|
|
The outer lip is dilated, undulated, tinged with black, or a deep brown upon the edge. The inner lip is whitish, spread out in a very thin plate upon the belly of the body whorl. The columella is smooth, polished, and forms at the left of the umbilicus a thick rib, marked by transverse striae, which terminates at the emargination of the base. The external surface of this shell is of a uniform reddish fawn color ; nevertheless the ribs are varied with wide spots or irregular brown and white blotches which are very remarkable.

The length of the shell attains 6.7 mm, its diameter 2.2 mm. This abundant little white species, has a fusiform shape narrowed below, with swollen upper whorls, and coarse spiral lirae, hexagonal, with very beautiful spiral, minutely punctate striae between the lirations just mentioned. The aperture is rather small, proportionately speaking Melvill J.C., 1917.

The whorls are prominently keeled above the suture, the keel being finely crenulate. The base of the shell is a little convex, excavated towards the peripheral keel, with three fine spirals at some distance from the periphery and a few, scarcely visible ones towards the central part, moreover with numerous very fine curved growth striae. The umbilicus is moderately large, pervious, scalar, with a rib at its margin and a groove just around this rib. The aperture is subtriangular, its margins broken, the upper one convex, the basal one nearly straight.
|
|
These lirations become more conspicuous on the lower whorls, which have the median keel, another one just below the suture and in some parts traces of a third one, running entirely or partly in the deep suture. Moreover, the whole shell is covered with microscopic, close-set, spiral threads. This sculpture is crossed by conspicuous riblets, fainter on the upper whorls, very strong on the lower ones, and by very fine growth- striae. The riblets are not close-set and form conspicuous spines below the suture of the lower whorls.
|
|
The pronotum and propodeum each have convex upper profiles, with approximately 25 concentric striae circling the pronotum. There is a large backward curving spine formed from the upper domed surface of the petiole, being a little narrower than the width of the petiole, and a smaller process is positioned on the forward underside area of the petiole. The worker is incomplete, missing the legs and antenna of the left side plus tip sections of the right legs. The third through end segments of the gaster are shrunken and missing.

Paeromopus millipedes are long and cylindrical, measuring in length and up to 8 mm (0.3 in) wide, with 68 to 80 body segments. The body color in most is brown to black with bands of light brown or yellow, although some individuals are dark gray or bluish gray with indistinct bands. The legs are relatively long, and the first pair of legs in males is extremely reduced in size. Like other paeromopodids, species of Paeromopus have fine parallel grooves (striae or striations) on each body segment, giving a somewhat roughened appearance.

Philip O. Gravelle developed the comparison microscope for the identification of fired bullets and cartridge cases with the support and guidance of Major Calvin H. Goddard. It was a giant leap in the science of firearms identification in forensic science. The firearm from which a bullet or cartridge case has been fired is identified by the comparison of the unique striae left on the bullet or cartridge case from the worn, machined metal of the barrel, breach block, extractor, or firing pin in the gun. It was Gravelle who mistrusted his memory.

Both sexes can produce chirps as distress calls at slightly less than the volume of a typical alarm clock (around 60 decibels) by rubbing their pronotum against the striae of their front wings. Males also stridulate for courtship, though usually only when all other tactics have failed. Males have also been observed stridulating to one another in the absence of females, one of many examples of same-sex sexual behavior in cockroaches. In courtship, the chirps are combined into "sentences" that may be up to three minutes long.
|
|
There is usually, too, a third ridge or carina, generally coarsely nodose, between the two already described. The base of the shell is more or less convex, generally shows microscopic concentric striae under a lens, and has about 5 low, narrow, separated spiral lirulae. The columella and the inside of the umbilicus are either green or white.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia (described as Chlorostoma coronulatum) This species is thus characterized by the two angulations on the body whorl and the fine, spiral sculpture between the two keels.
|
|
The plicae more or less project at the suture and on the edge of the basal whorl, producing an undulating or crenulated effect. Otherwise sculptured by incremental striae which traverse the surface and cross the plicae at right angles. The base of the shell is concave, radiately, closely and prominently striated, more conspicuous flattened, coalescing and sinuously curving at the edge. Commencing at the point where the outer lip joins the body whorl, a shallow groove follows parallel to the periphery and extends toward the aperture without interrupting the basal sculpture.

This suggests that the Itcha Range was glaciated repeatedly during the Pleistocene epoch. Glacial striae on polished surfaces of some of the oldest volcanic rocks in the eastern part of the shield and the local presence of drift deposits throughout the stratigraphy indicate that glaciation and volcanism were contemporaneous through much of the volcanic history of the Itcha Range. With a maximum elevation of , the Itcha Range is the lowest of the three Anahim shield volcanoes. Its highest point is Mount Downton, which is situated in the middle of the shield.

The Fueguian sprat or Falkland sprat (Sprattus fuegensis) is a herring-like, marine fish in the family Clupeidae found in the subtropical southwest Atlantic Ocean from 40° S to Tierra del Fuego and the Falkland Islands. Its depth range is from the surface to 10 m, and its length is up to 18 cm. The Fueguian sprat has a lower jaw slightly projecting, and a gill cover without bony radiating striae. The last two anal fin rays are not enlarged, and there are no dark spots on the flanks.
|
|
The wingspan is about 18 mm. The forewings are yellow, with the costa to the middle suffused with fuscous and with a fuscous terminal blotch containing long whitish longitudinal striae preceded by two transverse iridescent purple streaks. There is a yellow dot on the costa before the apex, and another minute dot on the dorsum at three-fourths, as well as five blackish dots on the lower half of the termen, of which alternate three are partly edged with brilliant gold. The hindwings are yellow with the margin around the apex fuscous.

|
Adult shell size varies between 48 mm and 154 mm. The ovate, conical shell is whitish, ashy or reddish, often with two brown bands which are sometimes interrupted. The spire is formed of seven or eight distinct whorls, flattened above, furnished with longitudinal, almost perpendicular folds, which are themselves intersected by striae visible only in the interstices of the folds, except towards the base, and upon the whorls at the top of the spire. The upper edge of the whorls is flattened, and bordered by rounded tubercles, which are separated from the longitudinal folds by a deep stria running below them.
|
|
They curve occlusally near the cuspal regions or the incisal regions. Produced during the second stage of enamel calcification, also known as the maturation stage, ameloblasts produce matrix and enamel at the rate of 4 micrometers per day; however every fourth day there is a change in development. Brownish lines, the striae of Retzius, develop as a result of a change in the growth process. Macroscopically, these lines can be seen on the labial surface or lip side of anterior or front teeth as horizontal lines on the tooth crown, also known as perikymata or "imbrication lines" .
|
|
Other axial sculpture consists of rather irregular, more or less prominent incremental lines. The spiral sculpture consists of three or more somewhat obscure incised lines over the fasciole. On the basal side of the whorl are numerous rather distant, distinct spiral striae, subequal and nearly equidistant, the interspaces a little elevated and, on the canal, becoming threads. In addition to these there are on the middle of the whorls a quantity of irregular, oblique, somewhat vermicular, short incised lines, the interspaces between which are faintly beaded or reticulated by the short segments they intercept of the incremental lines.
|
|
The suture is obscure, appressed, with a marked thread at its edge. The spiral sculpture consists of fine spiral striae over the entire shell, and (on the spire two or three, on the body whorl eight) stronger cords undulated but not nodulated where they pass over the axial sculpture, and separated by wider interspaces. The anal fasciole is hardly constricted. The axial sculpture consists of fine sharp incremental lines cutting the minor spirals and, on the body whorl about 13 low rounded ribs extending from the fasciole nearly to the siphonal canal but not conspicuous anywhere, with equal or narrower interspaces.
|
|
The spirals are about eighteen, and about seven of the upper ones are more or less nodulous on crossing the ribs, the rest below are finer and smooth. Between the nodulous lirae, both on the spire and on the body whorl, there are fine threadlike lines, and the whole surface exhibits delicate wavy growth- striae. The aperture is brown within, not quite one-third the length of the shell. The outer lip is thin at the edge, distinctly sinuate below the sutural keel, and having a rib or varix, larger than the other ribs on the outside.
|
|
Subsequent whorls (excepted last one), practically exist only of the excavation, which is sculptured by curved, raised striae and is bordered, just below the suture, by a conspicuous, spiral liration, with laterally compressed, fold-like beads. These become fainter towards the aperture. Just above the suture, a second row of depressed, slightly pointed tubercles, form a keel below the excavation of the body whorl, about 12 in number on that whorl, where they form the top of short, oblique, axial ribs. The lower part of the body whorl contains about 15 lirae and a few intermediate ones.
|
|
The aperture is ovate, notched at the top of the outer lip, with a ridge upon the inner lip. The depth of the cavity is brown, and marked with a whitish band. The outer lip is thin upon the edge, crowned throughout its whole length with small, short, and pointed denticulations, furnished internally with numerous transverse striae. The columella is arcuated, covered by the inner lip which extends upon the body of the body whorl in a white, rather thick callosity, loaded towards the base with some slightly apparent guttules, and terminated by small spinous points.
|
|
Thick shell is cylindrically turbinated, somewhat inflared, and varies in length between 25 mm and 90 mm. The spire is of varying height (mostly short), and with distant, spiral ridges on the lower half of the body whorl. The whole surface is distantly encircled by granular striae. The colouration is variable: often creamy orange, variously painted with chestnut longitudinal irregular streaks, usually forming three broad series or bands, zigzagging lines on upper part of body whorl and spire, and with brown bands across central and lower half of body whorl; or pale orange with white shoulder mottling and a central band.
|
|
The shell is covered with a large number of spiral lirae, often with intermediate ones, the number of lirae being about 7 on the penultimate whorl, but amount with the intermediate ones to 15 or 16. They are crossed by numerous riblike striae, producing short spines on the points of intersection, and very fine lines of growth. On the upper whorls the lirae diminish in number, they become nearly obsolete on the uppermore whorls, and disappear at last, leaving only the concentric ribs. The suture is deep, especially between the penultimate and ultimate whorls, on this last the suture descends conspicuously.
|
|
The antennae are ferruginous and the eyes are ovate (shape resembling an egg). The head is emarginate (having a notched tip or edge) from its posterior view and also rugose, along with the thorax and node (a segment between the mesosoma and gaster); these body parts are covered with large confluent punctures. The basal segment of the abdomen has transversely curved striae (grooves which run across the body). The colour of the thorax is usually greenish, the wings are subhyaline (they have a glassy appearance), and the nervures (the veins of the wings) are testaceous (brick-red colour).
|
|
A border is defined by a furrow running parallel to the margin of the cephalon, and this border furrow is deep at the front. The areas outside the axis are almost flat. Between the front of the glabella and the border, is a somewhat convex area of the cheek that is comparable in length (along the midline) to the occipital ring. In well preserved specimens the cheeks in front of the eye are adorned with very fine ridges (or striae) that probably represent parts of the digestive system (see Kordule, 2006, p. 283, figure 2.a/f).

Lasers have many uses in medicine, including laser surgery (particularly eye surgery), laser healing, kidney stone treatment, ophthalmoscopy, and cosmetic skin treatments such as acne treatment, cellulite and striae reduction, and hair removal. Lasers are used to treat cancer by shrinking or destroying tumors or precancerous growths. They are most commonly used to treat superficial cancers that are on the surface of the body or the lining of internal organs. They are used to treat basal cell skin cancer and the very early stages of others like cervical, penile, vaginal, vulvar, and non-small cell lung cancer.

In 1885 he clinically described what he called senile macular disease, today known as senile or age-related macular degeneration (AMD), and investigated the atrophic and pigmentary changes in the macular region of the eye associated with the condition. His name is associated with several medical eponyms, that include: "Haab's reflex", which is another name for pupillary light reflex, and "Haab's magnet", a powerful magnet used for removing metallic particles from the eye. Also, the "Haab scale" is a device used to measure pupillary diameter, and "Haab's striae" are horizontal breaks in the Descemet membrane associated with congenital glaucoma.

Like other ghost crabs, one of the claw appendages (chelipeds, the first pereiopod pair) of gulf ghost crabs is much bigger than the other. The palm of the larger cheliped is broad with a granular texture on the upper surface and finely serrated on the bottom edge. The inner surface of the palm features stridulating (sound-producing) ridges, which is important for identifying different species within the subfamily Ocypodinae. In gulf ghost crabs, the stridulating ridge is short and composed of a row of 11 to 13 tubercles, spaced more distantly and with striae (thin lines) on the upper half.

Forewing with a subterminal series of blue or sometimes slightly green elongate spots, curving strongly inwards and getting more elongate opposite the apex, forming almost an oblique bar up to the costa. Hindwing: the terminal margin broadly bright chestnut, sometimes with a subterminal paler spot in two or more of the interspaces. Underside pale brown, the basal two-thirds of both forewing and hindwing densely, the outer third more sparsely covered with dark ferruginous, somewhat broad, transverse striae. Forewing with a broadly triangular pale purplish- white preapical mark; both forewings and hindwings with a broad subterminal area purplish white.
|
|
The 12 whorls remaining are flat, with the smooth peripheral angle immediately above the suture, but scarcely projecting, a little more prominent on the upper than on the lower whorls. The surface of each whorl is a trifle concave, and sculptured with about 6 low, unequal spiral cords. Below the peripheral angle the body whorl is sculptured with about 25 spiral grooves, weaker above, stronger and closer below; and the growth-striae curve strongly backward near the angle. The aperture is very narrow, and of equal width throughout, and two-thirds as long as the shell.

Sinoceras is an extinct genus of nautiloids from China included in the family Orthoceratidae that lived from the middle Ordovician until the Devonian. The type species, S. chinense, was originally described as "Orthoceras chinense," but then was promoted by Shimizu and Obata to its own genus, Sinoceras, in 1935. The shell of Sinoceras is like Michelinoceras in that it has a slender orthoconic shell but the camerae are shorter and septal necks proportionally longer, reaching nearly a third the camera length. The surface in some is marked either by very fine irregular striae or by sinuous transverse growth bands.
|
|
The interior of the aperture is rosy white, the region about the canal deep rose color. The only sculpture on the sides of the shell consists of about six equidistant channeled sulci, growing wider anteriorly until the siphonal canal is reached, and a few smaller striae on the siphonal fasciole. The aperture is narrow, parallel-sided, with a straight outer lip, the anterior and posterior sinuses moderately deep. W.H. Dall, Summary of the shells of the genus Conus from the Pacific coast of Americain the U. S. National Museum; Proceedings of the United States National Museum.

Lichen planus (LP) is a chronic inflammatory and immune-mediated disease that affects the skin, nails, hair, and mucous membranes. It is characterized by polygonal, flat-topped, violaceous papules and plaques with overlying, reticulated, fine white scale (Wickham's striae), commonly affecting dorsal hands, flexural wrists and forearms, trunk, anterior lower legs and oral mucosa. Although there is a broad clinical range of LP manifestations, the skin and oral cavity remain as the major sites of involvement. The cause is unknown, but it is thought to be the result of an autoimmune process with an unknown initial trigger.

All of them are found in the Indo-Pacific region with more or less limited ranges, with the exception of Ocypode ceratophthalma, which is found widely. Ocypode cursor, found in the Atlantic and the Mediterranean Sea, also possesses a tuft of bristles at the end of its eyestalks. Stridulating ridges also differ from species to species, with some displaying rows of tubercles, others displaying rows of smaller ridges (striae), or a combination of both. These are very important in identifying species as they are displayed by both adults and juveniles (though they may be absent in newly regenerated claws).

The size and shape of the bite marks match the teeth of Tarbosaurus, the largest known predator from the Nemegt Formation. Various types of feeding traces were identified; punctures, gouges, striae, fragmentary teeth, and combinations of the above marks. The bite marks probably represent feeding behavior instead of aggression between the species, and the fact that bite marks were not found elsewhere on the body indicates the predator focused on internal organs. Tarbosaurus bite marks have also been identified on hadrosaur and sauropod fossils, but theropod bite marks on bones of other theropods are very rare in the fossil record.

Gassiot was a close associate of William Robert Grove at the Royal Society, encouraging Grove to join the London Institution where the two worked together on the development of photography. Gassiot's work was particularly important in the demise of the contact theory of voltaic electricity. Starting in 1840 he performed a number of experiments culminating in 1844 where he used a battery of 100 mutually insulated Grove cells to show that a spark could be drawn before an electrical contact was made. Gassiot extended Groves's work on striae in electrical discharges, showing that the discharge cannot continue in a vacuum.

Mecodema atrox is a medium-sized (17–24 mm length, 6–8 mm width) ground beetle species that is closely related to Mecodema curvidens (a very widespread species throughout the Bay of Plenty and Central Plateau). Mecodema atrox is relatively rare in comparison due to its preferred habitat, the coastal broadleaf forests of the Coromandel Peninsula, a forest type that is in decline. The body of Mecodema atrox is black and the legs are dark reddish- brown. They can be distinguished from other Mecodema species by a number of characters, including the pattern of asetose punctures along the elytral striae.
|
|
The forewings are white, transversely striated throughout with brownish ochreous and more or less irrorated (sprinkled) with dark fuscous and blackish, the coalescence of these striae indicates a small basal patch, a narrow fascia from one-third of the costa to before the middle of the dorsum, with the posterior edge angulated below the middle. There is a narrow fascia from two-thirds of the costa to the dorsum before the tornus, and a slender more or less marked inwards-sinuate fascia from the costa before the apex to the tornus. The hindwings are pale fuscous.
|
|
Head and thorax pale fulvous yellow; palpi crimson, black at tips; sides of frons and antennae black; pectus in front blackish, some blackish and crimson below shoulders; fore coxae crimson; (legs wanting); abdomen crimson, the ventral surface pale ochreous, lateral series of slight blackish points. Forewing pale ochreous yellow; small postmedial black spots above and below vein 1. Hindwing yellowish white, the inner area rather yellower; a small black discoidal spot. Underside of forewing with black discoidal lunule and oblique blackish postmedial striae from vein 5 to below vein 3; hindwing with the costal area yellower.

The halloween hermit crab is commonly found along coral substrates in the ocean, along sandy areas surrounding reefs, but not typically on top of the reefs themselves, in shallow (less than ) tropical, coastal waters. It is native to the Indo-Pacific region, including the Red Sea and Hawaii. It is very similar in appearance to three other species in the same genus: C. tricolor, C. vakovako and C. galzini, only distinguishable by the color of its striae. The halloween hermit crab will grow on average to in length, which is fairly large in comparison to other hermit crabs.

|
The whorls are six or seven in number, and very approximate; the four or five upper ones are conical, covered with subnodulous, longitudinal folds, which gradually become effaced, and disappear altogether upon the body whorl. This is partly smooth, pretty strongly furrowed at its base, larger than all the others, and separated by a broad and deep suture, forming a kind of scaffold, which renders it very round above. The other whorls are not very apparent. At their surface is seen, besides the longitudinal folds of which we have spoken, transverse striae which terminate in the body whorl.
|
|
The small spire is nearly terminal and laterally inclined. The open aperture is very much lengthened.H.A. Pilsbry (1890) Manual of Conchology XII; Academy of Natural Sciences, Philadelphia, 1890 (described as Gena lentricula) Schepman gives a somewhat divergent description: the posterior part of the shell is nearly entirely yellowish- white with a green tinge, moreover a few smaller patches of the same colour are dispersed over the anterior part, a few dark spiral lines are more conspicuous on the posterior part. The surface is covered with very fine, close-set spiral and by more remote concentric striae.

The offspring valves are formed within a silica deposition vesicle that gradually grows larger and separates into two different offspring valves. The parent valves become a template for the offspring valves being formed, with patterns of striae and the central cell area also being inherited. However, perfect complementation does not occur every generation, which can lead to consecutive generations inheriting a deformed parental valve that was initially a deformed offspring valve in a previous generation. The likeness of the offspring valves to the parental valves is determined by the flexibility of the girdle bands; the other factors are unknown.

Map of ancient sites on the Beara Peninsula The peninsula was glaciated during the quaternary period; evidence from this era survives in the form of striae around Hungry hill, and erratics on the western road into Glengarriff. The first signs of human activity date to c 3000 BC, and consist of traces of Early Bronze Age settlements. The landscape is rich in megalithic monuments and other prehistoric archeological sites, including over 70 standing stones, 22 stone rows, 38 dolmens, as well as wedge tombs, stone circles. Later the area became a Viking settlement, as evident in place names such as Longhart.

The wingspan is about 17 mm. The forewings are brown, with a faint purplish tinge, speckled grey, crossed by indistinct paler transverse striae, towards the anterior half of the costa suffused darker, the posterior half of the costa and termen speckled white. The discal stigmata are small and dark fuscous and there is a short oblique mark of white irroration from the costa before the middle, and a white mark on the costal edge at the beginning of the white irroration, the costa between these darker brown. There is a dark brown mark on the costal edge at three-fourths.

Later on he discussed the origin of the elevated shell-bearing gravels near Dublin and expressed the view that they were accumulated by floating ice when the land had undergone submergence. In 1872 George H Kinahan and Maxwell Close published jointly an important paper entitled The Glaciation of Iar-Connaught and its Neighbourhood in the Counties of Galway and Mayo. It was a private publication, accompanied by a large map showing the pattern of striae over Connemara and south Mayo. He was for a time treasurer of the Royal Irish Academy, an active member of the Royal Dublin Society, and president in 1878 of the Royal Geological Society of Ireland.

The nuclear whorls are smooth, turgid, the subsequent turns carrying a rounded low keel, usually in front of the middle of the whorls forming the pire, the area between which and the suture is flatly impressed, the whorl in front gently rounded. On some of the early whorls the keel is slightly undulated, but not regularly nodulous. Besides the lines of growth, both the fasciole and the anterior part of the whorl show indications under a lens of obscure regular distant spiral striae, and are also more or less marked with a faint vermicular reticulation of the surface. The distinct suture is not appressed.
