Original Description
Shell papillate, slender, pyramidal. Cephalis small, hemispherical, with a straight conical horn twice the length, and small circular pores. Thorax conical, with slightly convex outlines and nine stout, somewhat curved ribs in zig-zag form, which are connected by ten to twelve interrupted transverse bars. From each nodal point a small conical papilla arises. The large meshes so produced are regular, hexagonal, gradually increasing in size towards the mouth.

Size: Cephalis 0.03 diameter; thorax (with twelve transverse rows of meshes) 0.18 long, 0.12 broad.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Sethopyramis hexagonalis under the subgeneric name Cephalopyramis, but did not include the subgeneric name in the species name.[comment from RadWorld database]
