Rhynchorthoceras is a Middle Ordovician genus characterized by a rapidly expanded, weakly annulate orthocone, like the orthoconic section of Ancistroceras, but with only a curved, cyrtoconic apex instead of juvenile whorls. Rhynchorthoceras is probably derived from Ancistroceras by a loss of the tarphycerid type apex, although it has been included with the orthocerid Sinoceratidae.

Glenesteroceras, which is of questionable validity, is based on a single specimen from the Lower Ordovician of New York state, described by Rousseau Flower, 1957. Glenestoceras is described as being a weakly annulate orthocone with a circular cross section and large central siphuncle with slightly divergent necks, thick connecting rings, and expanded segments. Description is based on an incomplete immature phragmocone with a 5mm cross section.

Annulate lamella is one of the cell membrane classes, occurring as a set of parallel elements with double same dimensional membranes, just as the nuclear envelope. These lamella have pore complexes which are identical to those of the nuclear cover. It is arranged in highly ordered structure with a regular spacing between themselves. These lamella are characteristics for the oocytes, spermatocytes, some somatic and cancer cells.
|

The nucleus is indented and ovoid and can be lobulated. They also contain rough endoplasmic reticulum, nuclear envelope, and annulate lamellae, which all contain peroxidase activity. Both the centrilobular and periportal regions of the liver, house Kupffer cells, but their function and structures change depending on their location. Periportal Kupffer cells tend to be larger and have more lysosomal enzyme and phagocytic activity, whereas centrilobular Kupffer cells create more superoxide radical.

The genus was first described by American mycologist William Alphonso Murrill in 1909. He defined species in the genus as having a cap and stem "clothed with a conspicuous sulphur-yellow, powdery tomentum, which may be the remains of a universal veil: context white, fleshy; tubes adnate, yellowish, covered with a large veil: spores oblong-ellipsoid, ochraceous-brown: stipe solid, annulate, not reticulate." Murrill set Pulveroboletus ravenelii as the type species.

Ancistroceras is one of the two ancestral lituitids from the late Early Ordovician (Arenigian). The other being Holmiceras. The shell is weakly annulate, starts off with 1.5 to 2 contiguous or slightly separated whorls followed by a rapidly expanding orthocone with an apical angle of about 30 deg. Growth lines are sinuous, show a pronounced hyponomic sinus in the coiled juvenile portion at the apex but almost none at the mature aperture of the orthcone.

Ellinoceras is a genus of small, straight, annulate actinoceratid from the Middle Ordovician of northeastern Siberia with strongly sinuous sutures and subcentral siphuncle. Sutures have 14 narrow lobes and saddles, the ventral lobe deep and broad with a small median saddle. The siphuncle segments are short and broad with short necks and a wide endosiphuncular tube. Ellinoceras somewhat only superficially resembles other members of the Actinoceratidae and is distinct mainly by its sinuous sutures.
|
|
The Lituitida are the Lituitidae of the Treatise (Furnish & Glenister,1964), reranked as an order and combined with other orthoceratoids. They are considered to be more closely related to the Orthocerida than to the Ascocerida or Pseudorthocerida which are also included. Lituitids are characterized by smooth to annulate shells in which the juvenile portion near the apex is coiled or cyrtoconic. The adult portion is straight or slightly sigmoidal and may be expanded.

The legs are mostly uniformly pubescent with appressed hairs (white, tawny, iridescent green, in some combination), somewhat mottled; apex and basal 1/3 of tibiae annulate due to less dense pubescence exposing darker integument. Tibiae approximately equal in length to femora; hind legs much longer than forelegs; metafemora extending to about abdominal apex. Tarsi generally covered with short, appressed, pale pubescence; apex of fifth tarsomere sparsely pubescent, dark.

The genus Flabellina was established by John Edward Gray in 1833 with the type species Flabellina affinis and characterised by the cerata being arranged on peduncles and the rhinophores being annulate. Many species were added by subsequent authors. In 1981 the genus Coryphella was merged under the older name Flabellina as despite a large range of morphological characters in the 64 species of Flabellinidae and Coryphellidae known at that time, no clear distinction could be found to separate the species into the two genera.Gosliner T.M., Griffiths R.J. (1981) Description and revision of some South African aeolidacean Nudibranchia (Mollusca, Gastropoda).

The beetle is long and wide. The head is covered throughout in dense, appressed, mottled tawny, white, or pale green pubescence, with exception of a mostly obscured, narrow, median-frontal line extending from fronto-clypeal margin to between lower eye lobes and short, glabrous frontal-genal line extending from anterior tentorial pits along anterior margin of genae to base of mandible. The antennae are covered with dense, appressed, mottled white and tawny pubescence; annulate at apex and base of most antennomeres. Last antennomere uniformly dark, without annulae, of similar coloration to apex of penultimate antennomere. Antennae longer than body, extending beyond apices by 3-4 antennomeres.

Distinguishing Lactarius from Lactifluus based on morphology alone is difficult; there are no synapomorphic characters known so far that define both genera unequivocally but tendencies exist: zonate and viscose to glutinose caps are only found in Lactarius, as well as closed (angiocarpous) and sequestrate fruitbodies. All known annulate and pleurotoid (i.e., laterally stiped) milk-caps, on the contrary, belong to Lactifluus. Characters important for identification of milk-caps (Lactarius and Lactifluus) are: initial colour of the latex and color change, texture of cap surface, taste (mild, peppery, or bitter) of latex and flesh, odor, and microscopical features of the spores and the cap curticle (pileipellis).

The forewings are bone-ochreous, sprinkled with brownish fuscous scales, which are chiefly distributed in horse-shoe form around the outer end of the cell, reverting to the costa and dorsum at or before the middle and tending to radiate outward on the lines of the neuration. An outwardly waved series of spots lies beyond this shade, annulate below the costa, bowed in the middle and sloped backward to the dorsum before the tornus. There are two strong discal spots, one before the middle, the other at the end, of the cell, with a plical spot nearer to the first. There is also a series of six well-marked spots along the termen, at the base of the bone- ochreous cilia which are tipped with whitish.
