Original Description

Has the same four primary spines and the same three primary arches as Plectacantha. There is, however, also a ventral, sagittal spine, which is less strongly developed than the others (""der secundäre Mittelstachel Jørgensen, 1900, p. 77). The network, as in Plectacantha, is at a late stage and only imperfectly closed beneath.
