; ovate, gently rounded posteriorly and anteriorly; equivalve, strongly inequilateral; rather compressed; thin; white, showing spots and blotches in the substance of shell which lend to it a watered silk effect. The umbones are low and strongly prosogyrate and are situated near the anterior end. Prodissoconch, P1 typically eroded, possibly D-shaped, ca. 130 µm length by 85 µm height, P2 ovate with slender growth lines, white to tan in color, ca. 430 µm length by 369 µm height. In adult valves the dorsal line curves gently from the umbo to the posterior end. The surface is nearly smooth, marked by weak commarginal growth stops only. The elongate lateral dorsal tooth, stronger expressed in the receiving LV is marginally placed. The shorter anterior laterals are equally marginally placed. The single cardinal tubercles in either valve rest at the upper margin of the anterior lateral. The laterals are smooth not serrated. The posterior scar is narrow, elongate, rather small and marginally placed; the posterior scar is suborbicular, also small and marginally placed. The connecting, continuous pallial line is very weakly impressed, but comparatively broad and patchily interrupted. The margins are smooth.
