Original Description
Frontal ring kidney-shaped, nearly twice as broad as high, with a flat sagittal constriction. Sagittal ring semicircular. The four gates between the two rings are partly fenestrated by an arachnoidal network, composed of thin, irregularly branched threads, arising from the rings. The edges of all three rings are armed with irregular thorns. Basal gate circular, larger than the sagittal ring.

Height of the frontal ring 80µm, breadth 140µm.

Editors' Notes
[It is clear from the family discussion of Coronida [1041:967-969] that Haeckel meant to assign the following key to the letters on the illustration: r = primary saggital ring; q = lateral or frontal ring; s = horizontal basal ring.]
