Auricles are unequal, anterior is larger than posterior. Byssal notch is weakly developed. Apical angle 85°- 110°. Sculpture on both valves is identical and consists of 11 radial, sharpangled costae with wide interspaces. On slopes of ribs and within interspaces very fine radial striae are situated. Concentric sculpture from fine growth lines and wrinkles, which, intersecting with the radial sculpture, form scales and protuberances lacking power on ridge of radial ribs. Comparisons and comments.
