Original Description
Frontal ring violin-shaped, on the upper and the lower margin concave, with a deep sagittal constriction; its two halves pentagonal. Between numerous smaller spines there arise from the frontal ring six groups of larger branched spines, two odd in the corners of the highest points (curved like two horns), two branched pairs on the prominent lateral corners (at right and left), and two pairs in the corners of the lowest points (like four branched basal feet). Sagittal ring only two-thirds as high, with four pairs of irregular spines.
Size: Height of the frontal ring 0.11, breadth 0.16.
Editors' Notes
Haeckel listed Zygostephanus bicornis under the subgeneric name Zygostephaniscus, but did not include the subgeneric name in the species name.
Figure. It is clear from the family discussion of Coronida (p.967-969) that haeckel meant to assign the following key to the letters on his illustration: r = primary sagittal ring; q = lateral or frontal ring.[comment from RadWorld database]
