Original Description
Shell slenderly ovate, with three distinct strictures. Length of the four joints = 2: 6: 7: 6. Cephalis subspherical, with a stout pyramidal horn of the same length. The three following joints have nearly equal length; the third is the broadest. The thorax exhibits three divergent solid ribs; as prolongations of these, three descending latticed wings, of about the same length, arise from the third joint, with broad triangular base. The fourth joint is inversely conical, blunt. Pores irregular, roundish. (Similar to Hexalatractus fusiformis, Pl. 68, fig. 13, but with three wings and four joints.)

Length of the shell (with four joints) 0.21. Breadth of the third (broadest) joint 0.11. Length of the single joints, a 0.02, b 0.06, c 0.07, d 0.06.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Cyrtopera gasteroptera under the subgeneric name Artopera , but did not include the subgeneric name in the species name.

This species is assigned to Artopera (the senior synonym) Haeckel, 1881a (non Haeckel, 1887a).
