Anterior margin sharply sinuous dorsally, ventrally strongly convex and extending well forward of umbones.

Outer surface covered with concentric lamellar processes, with very low radial ridge ending at posteroventral angulation. Ligamental area with a dozen transverse grooves. Nacreous area of the inner side of shell surrounded by a broad, non-nacreous margin. Colour: outside of shell horny to purplish brown. Interior nacreous, with a broad dark brown margin.
