Original Description Cenodiscida with four radial spines on the margin of the disk, crossed in the equatorial plane. Etymology: From the Greek crucidiscus = disk with cross" Extra details from original publication The genus Crucidiscus is the most simple form of the Staurodiscida, or of the numerous Discoidea (belonging to different families) in which the margin of the disk bears four radial spines, lying in the equatorial plane, and crossed at right angles. Whilst commonly the internal shell-cavity of Crucidiscus is quite simple, in one case it bears four centripetal axial rods, as inner prolongation of the outer radial cross-spines, perhaps indications of a lost medullary shell (comp. p.410).
[The discussion on p.410, referred to in the text, is part of the family description for Cenodiscida.] Sub-genera described:
