Original Description

Shell broadly ovate, with three slight strictures. Length of the four joints = 1: 2: 3: 4. Cephalis hemispherical, with a slender, pyramidal horn of three times the length. Along the second and third joints arise with broad base three latticed, triangular wings, nearly as long as the whole shell. Abdomen inflated. The fourth joint is the broadest and longest, with hemispherical basal pole. Pores subregular, hexagonal. (Similar to Artopilium longicorne, Pl. 77, fig. 10, but with more closely reticulated network, and perfectly closed mouth.)

Length of the shell (with four joints) 0.2. Breadth of the fourth (broadest) joint 0.14. Length of the single joints, a 0.02, b 0.04, c 0.06, d 0.08.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Cyrtopera ornithoptera 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).[comment from RadWorld database]
