Original description: Disk with spiny surface, three times as broad as the medullary shell. Pores irregular, roundish ,or polygonal; eight to ten on the radius. Marginal spines thirty to fifty, pyramidal, angular, of very variable size, number, and disposition, gradually passing into the surface-spines; the largest nearly as long as the diameter of the medullary shell.
Remarks on original description: Haeckel listed Heliodiscus echiniscus under the subgeneric name Heliodiscilla, but did not include the subgeneric name in the species name.[comment from RadWorld database]
