• The major uncinus is stout and has a large four-toothed ovate cusp.
• The species " uncinus " is similar but has upturned hooks at the ends.
• It is sometimes seen with the fibratus and uncinus species of cirrus, the stratiformis species of altocumulus and stratocumulus, the mediocris and sometimes humilis species of cumulus, and with the genus altostratus.
• The streaks point in the direction of the wind and may appear straight, giving the clouds the appearance of a comma ( cirrus uncinus ), or may seem tangled, an indication of high level turbulence.

• Another variety, " duplicatus " ( closely spaced layers of the same type, one above the other ), is sometimes found with cirrus of both the fibratus and uncinus species, and with altocumulus and stratocumulus of the species stratiformis and lenticularis.
• The radula has a large simple rhachidian tooth with, on each side, two large, simple transverse laterals, followed by two minute ones, and a large outer lateral with a strong tridentate cusp, outside of which is a single scale-like flat uncinus, bearing an elongated thickened ridge, but no cusp.
• The "'uncinate processes of the ribs "'are extensions of bone that project caudally from the vertical segment of each rib .
