Original Description
Coronida with four large, partly latticed, lateral gates, without basal gate. Skeleton composed of two meridional rings perpendicular to each other.
The genus Zygostephanium differs from the preceding ancestral genus Zygostephanus in the development of lattice-work along the two crossed rings, produced by their anastomosing branches. Therefore the four large lateral gates between them, which are quite simple, in the preceding genus here become more or less fenestrated.
Etymology: Greek zygostephanium = small yoked ring"
Editors' Notes
[Although Haeckel here refers to p.446 in his Prodromus of 1881a, there is no genus named Zygostephanium on that or any other page of that reference.
