Original Description

Shell campanulate, with three slight strictures. Length of the four joints = 3: 5: 5: 4. Cephalis subovate, with an internal rod-cross, and a stout pyramidal horn of the same length. From the middle of the collar stricture arise three divergent collar beams, which descend in the upper half of the campanulate thorax as three divergent ribs, and are prolonged into three free horizontal spines. (In the specimen figured these three wings are very short; in another specimen, found afterwards, there were three solid, pyramidal, horizontal spines, as long as the cephalic horn.) The third joint is the broadest, of about the same length as the fourth. (The annular septum between the two latter is by a mistake not figured). Pores subregular, circular, hexagonally framed.

Size:
Length of the shell (with four joints) 0.17, breadth 0.12. Length of the single joints, a 0.03, b 0.05, c 0.05, d 0.04.

Editors' Notes
Haeckel listed Stichopilium campanulatum under the subgeneric name Triacartus, but did not include the subgeneric name in the species name.
Synonymized with Pterocorys zanclaeus (Müller) by Petrushevskaya, 1971c[comment from RadWorld database]
