Clathrocyclas universa Clark and Campbell, 1942

Description - Add description

Highly variable shell usually bell-shaped with similarly variable apical horn which is usually bladed, prismatic, or less often thick and clublike; cephalis commonly cap-like, more rarely conical; thorax long (up to nearly 0.5 total length), convex, and basally limitad by a transverse septal band; Abdomen often rim- or skirtlike; also, in some, cylindrical or flared conical; apertural margin having 12 or 20 triangular or lamillar, prong like teeth; wall generally rough; cephalis lacking pores, thorax having about sixty pores (or more) with strongly developed sepaloid points between them, the pores being in six or more tiers, pores of abdomen large, usually in a single principal row.
Clathrocyclas universa n.sp. differs from puella Haeckel (1887, = Podocyrtis puella sinensis Ehrenberg, 1875) from Barbados in shorter feet and fewer pores on abdomen. Three recent species—basilea Haeckel (1887), principessa Haeckel (1887), and collaris Haeckel (1887)—are assigned by Haeckel (1887, pl. 74, figs. 6, 7, 8) to Calocyclas as well as to Clathrocyclas.
