Original Description
Internal cortical shell thin walled, with irregular, roundish pores, once to three times as broad as the bars; ten to eleven on the half meridian of each chamber, fourteen to sixteen on its half equator. Outer cortical shell thin walled, with very delicate network, spindle-like, with conical prolongations at both poles. Distance between the two shells larger than the greatest diameter of the double lenticular medullary shell. Surface of both cortical shells covered with innumerable small thorns. (Resembles closely Cyphocolpus virginis, Pl. 40, fig. 11, but without the third shell.)

Main axis of the external cortical shell 0.21, of the internal 0.14; greatest breadth of the former 0.13, of the latter 0.09; pores 0.003 to 0.009; bars of the outer shell 0.001, of the inner 0.004.

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