Shell thick and solid, inflated, inequilateral, roughly quadrate in shape with arcuate ventral margin and obliquely truncate posterior margin; slightly inequivalve, left valve distinctly overlapping the right valve ventrally and posteriorly. Cardinal area rather long and narrow. About 33 radial ribs (30 to 36) at each valve; ribs as wide as the interstices, granulated on left valve. Periostracum well developed. Internal margins with strong crenulations corresponding with the external radial ribs. No byssal gape. Colour: outside of shell white under the blackish brown periostracum. Inner side whitish.
Common depth values based on occurrence. On fine muddy-sand bottoms (Ref. 126564), in bays and coastal lagoons (Ref. 348 and 75831).

Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam.
