Shell rather thin but solid, strongly inflated, oval subquadrate in shape with rounded ventral margin, almost as high as long; slightly inequivalve, left valve overlapping the right valve on ventral and posterior margins. Cardinal area moderately large. About 34 radial ribs (32 to 36) at each valve; ribs stout and flat, larger than the interstices, smooth on both valves. Periostracum coarse and concentrically striated, easily detached, forming rows of foliations in the interstices of ribs. Internal margins with strong crenulations corresponding with the external radial ribs. No byssal gape. Colour: outside of shell white under the dark brown periostracum. Inner side bluish white.
On fine muddy-sand bottoms, in bays and coastal lagoons. Littoral and sublittoral to a depth of 20 m (Ref. 348).

Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
