Pores circular, of different sizes, in the three first joints double-contoured. Cephalis subspherical, with a large, conical horn of three times the length. The fourth joint is inversely conical, three times as broad as the constricted mouth. Peristome with a coronal of numerous (ten to twenty) irregular, thin, partly forked teeth.

Size: Length of the shell (with four joints) 0.14, breadth 0.07. Length of the single joints, a 0.02, b 0.04, c 0.03, d 0.05.

Editors' Notes
Haeckel listed Cyrtophormis cornuta under the subgeneric name Acanthocyrtis, but did not include the subgeneric name in the species name. This species is assigned to Acanthocyrtis (the junior homonym) Haeckel, 1887a (non Haeckel, 1881a).[comment from RadWorld database]
