Diagnosis
ReferenceDiagnosis
A.S. Gale 2021A group of asteroids with spherical to subspherical body form, in which the abactinal surface is strongly domed and made up of relatively few, large, polygonal abactinal and actinal ossicles. Marginals are not differentiated. Primary (extra-ambulacral groove)
ossicles are tabular to sub-conical in form. Adambulacral-ambulacral articulations and inter-adambulacral contacts have cavities for probable attachment of ligaments. The primary ossicles are made up of three discrete stereom layers: an external one of dense perforate stereom, a middle one of rectilinear stereom and an internal one of labyrinthic material.
