Original Description

Archiphaenida (vel Monocyrtida multiradiata clausa) with an apical horn and simple internal cavity of the shell, without axial columella.

From the Greek calpophaena = urceolate shell"

Extra details from original publication
The genus Calpophaena and the following closely allied Archiphaena differ from the two preceding genera of Archiphaenida in the simple shell cavity, which encloses no columella. They may be derived either from the preceding Phaenocalpis by loss of the columella, or directly from the Zygospyrida by reduction of the sagittal constriction and loss of the primary ring. Different subgenera may be distinguished in Calpophaena according either to the number of the feet or to their shape (being simple or branched).
