Organism information awaits expert curation
Class: Bivalvia

Color: Shell is pale yellowish brown, mottled with large irregular purplish red blotches, but near the umbo it is white.

Shell is oblique and more or less ovate; there are about 32 well raised ribs, moderately narrow, closet-set radiating ribs with deep interstices between them; anterior ribs are transversely toothed; median ribs are smooth at the top, but finely toothed at the sides. 5-6 of the extreme posterior ribs are conspicuously tuberculated; strongly raised ribs and the well-excavated interstices between them give the margin of the shell a deeply undulating appearance in an end view. The interior of the shell is smooth and tinged here and there with pale pink; the radial ribs are indicated on the inner surface by opaque white radiating lines. Margin of the inner surface is deeply dented. Hinge teeth are stout and well developed.
