Description
Size: Ambital diameter (D) = 65-80 mm.

Color: Spines white, surface dark brown in ambulacral and interambulacral areas except along rows of tube feet where it appears mid brown. Primary spines normally inclined radially towards adjacent ambulacrum leaving clear test surface over most inter-ambulacrum giving the general appearance of a pentaradiate brown cross (Humphreys, 1981).

Aboral surface high and sloping, oral side flat. Ambulacra with three vertical series of pore pairs arranged horizontally. Ambulacral primary tubercles one after 3-4 plates. Primary spines short and whitish. Globiferous pedicellariae small and numerous. Ambulacral areas lighter contrasting with dark interambulacra. Gill slits deep and sharply defined.
