Original Description Shell smooth, with two deep strictures, similar to Cycladophora stiligera. Length of the three joints 1: 4: 3, breadth = 1: 4: 3. Cephalis subspherical, with a large, conical horn of three times the length. Thorax subspherical, with small, regular, circular pores. Abdomen cylindrical, with truncate mouth and few irregular pores of different sizes, commonly arranged in three or four subregular, transverse rows, with large intervening distances. Peristome with a corona of twelve to twenty vertical, lamellar feet, which are about as long as the abdomen, and truncate at the end (in Ehrenberg's figure these are broken off).

Editors' Notes There was no illustration of this species in Haeckel (1887) Haeckel listed Calocyclas minervae under the subgeneric name Calocycletta, but did not include the subgeneric name in the species name.[comment from RadWorld database]
