Posterodorsal margin short, slightly concave, forming a smooth, narrow curve when joining to posterior margin. Junction between posterodorsal and posteroventral margin as an obtuse smooth angulation.

Lateral dentition consisting of a rather strong, lamellar, grossly triangular tooth, continuous with hinge plate margin, with rather deep longitudinal grooves, and a wide submarginal socket with 2–3 small ridgelike teeth inside. Ligament pit external, wide, immediately posterior to beak, occupying all posterodorsal margin. Ligament pit wide, deep; pit margins with a deep groove for ligament insertion. Ligament thick, strongly bulging, partly covered by a thick periostracum. Inner valve surface white, dull. Pallial line fairly well distinct, no sinus. Anterior muscle scar large, ovate, marginal in position, below shell height midpoint; no posterior scar. Outer surface with shallow, ill defined, concentric riblets and thin growth striae.
