Original Description

Sagittal and frontal ring of equal size and form, larger than the circular basal ring. From the four corners, in which the latter crosses the two former, arise four strong, divergent spines, branched like a deer's antler. Some smaller spines are scattered on the rings, and a bunch of four spines arises on the apical pole. The four upper gates are triangular, the four lower nearly semicircular, the latter of equal size, half as large as the former.

Size:
Height of the frontal ring 0.13, breadth 0.14.

Editors' Notes
Haeckel listed Tristephanium quadricorne under the subgeneric name Tristephaniscus, but did not include the subgeneric name in the species name.[comment from RadWorld database]
