Shell of moderate size, subcircular, slightly inequilateral, apical angle about 95º, ears very unequal. Sculpture of right valve consisting of about 40 strong radial ribs many of them arranged in pairs and some double, the posterior and anterior ones noticeably finer; interstices somewhat narrower than the ribs and often with a central thread. Scaly concentric ridges are well developed in the interstices but are absent on the summits of the ribs (this may be due to wear). Anterior ear with five radials interstices crossed by spaced scaly ridges.
