Original Description
Shell thorny, slender, pyramidal. Cephalis small, subspherical, with few small pores and a straight, vertical, conical horn twice the length. Thorax with nine straight ribs, which are connected by sixteen to twenty complete transverse nine-angled rings. The large meshes so produced are subregular, square. From each nodal point a short conical spine arises. (Differs from the similar Bathropyramis spinosa, Pl. 54, fig. 4, by the development of the cephalis and the simple pointed, unforked spines.)
Size: Cephalis 0.03 diameter; thorax (with sixteen rings) 0.2 long, 0.12 broad.
Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Sethopyramis spinosa under the subgeneric name Cephalopyramis, but did not include the subgeneric name in the species name.[comment from RadWorld database]
