Original Description
Gate circular. Ring hexagonal, with three sharp edges and six pairs of large branched spines, arising from the flat lateral edges on the six corners. Each of the twelve spines is horizontally expanded, longer than the diameter of the ring and dichtomously forked like the antlers of a reindeer. If the lateral ends of the branches of this species become united in the frontal plane, we get Microcubus, the four upper spines forming the mitral ring, the four middle the equatorial ring, and the four lower the basal ring.

Diameter of the gate 0.08; length of the spines 0.09.

Editors' Notes
Figure: Although Haeckel never gives a key for the letters used on the illustration of this species, it is clear from the description here and from the family description of Stephanida on p.939 that he intends the following: m = mitral ring, n = equatorial ring, r = sagittal ring, c (usually called "s" in other illustrations) = basal ring.
