Anterior ambulacrum distinctively sunken, two-series of irregularly arranged, large pores, associated with tube feet; paired petals sunken, wide at internal fasciole, tapering distally. Periproct opening at truncated end, variable in shape. Internal fasciole conspicuously long, subanal fasciole shield-shaped, with four pore-pairs, pointed at end; anal fasciole extending along periproct, onto upper side, separated from subanal fasciole. Spines uniform. Live specimen brownish, denuded test white.
