Catalog entries: Clathrocyclas universa

Original 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 limited by a transverse septal band; abdomen often rim- or skirtlike; also, in some, cylindrical or flared conical; apertural margin having twelve to twenty triangular or lamellar, 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. Distinguishing characters (rw): Clathrocyclas universa n. sp. differs from C. puella Haeckel (1887 = Podocyrtis puella sinensis Ehrenberg, 1875) from Barbados in shorter feet and fewer pores on abdomen. Three recent species – C. basilea Haeckel (1887), C. principessa Haeckel (1887), and C. collaris Haeckel (1887) - are assigned by Haeckel (1887, pl. 74, figs. 6, 7, 8) to Calocyclas as well as to Clathrocyclas.
Remarks on original description: [The authors here list this species under the subgeneric name Clathrocyclia and include the subgeneric name in the species name.
