Plates bearing large spines, especially those on the arms, are typically bare aside from accessory granules, but smaller plates may be completely covered by smaller accessory granules. Pulpy membrane present over surface, obscuring granulation and plate surface near periphery of disk at contact with marginal plates. Madreporite convex, swollen with shallow sulci present on surface. Abactinal surface on arms is sharply distinct from plates on disk (

Plates slightly convex, bare except for spines, and one to four tubercular granules present infrequently. Superomarginals slightly offset relative to inferomarginals. One to four large, conical to chiselshaped spines per plate. Spines (three to four) and tubercles (one to five) present with higher numbers inter-radially. Spine number decreasing distally to one to two spines distally. More weakly developed spines on smaller specimen, with one to five bullet-shaped granules/tubercles present on plate surface. Single spines on inferomarginal plates form a distinct linear fringe. Pointed granules, 55–65 total, form periphery on marginal plates with approximately ten per side in contact with other marginal plates, approximately 15–18 per contact with abactinal surface. Terminal plate smooth but with three conical spines, two on distalmost tip, one on abactinal surface.

Six proximally and decreasing in number distally. Nine to ten furrow spines on first adambulacral plate. Furrow spines flattened, paddle like to triangular in cross-section many with roughened, worn down ragged tips. Degree of wear varies from spine to spine but seems more pronounced on proximal spines. Subambulacral ornament composed of a single large clam-shell to paddle-shaped pedicellariae proximal on the adambulacral and an extremely thickened, large spine, many with pronounced club-like to almost lobate head with worn tip sometimes with pronounced striations. Ambulacral and subambulacral series flanked by ten to 15 round, hemispherical granules varying in size. Largest adjacent to subambulacrals, becoming smaller and flatter adjacent to actinal inter-radial regions. Oral plates with four thick oral spines (quadrate in cross-section) projecting into mouth (two per plate) and four to five on surface of oral plate at apex of inter-radius. These latter spines are thick and round to quadrate in cross-section. Spines have worn tips with striations. Region between the oral plates and remainder of the actinal intermediate plates is covered by flattened, round granules, densely packed, similar to those adjacent to the subambulacral plates.</paragraph>
