Rightwards flexure of valves moderately strong, forming a depressed radial fold on posterodorsal slope of left valve. Umbones situated about mid-length of valves. Outer surface with numerous, regularly spaced, fine concentric ridges. Anterior cardinal tooth of left valve and posterior cardinal of right valve bifid. One anterior and 1 posterior lateral tooth in each valve, strong in right valve, feeble in left valve. Posterior lateral teeth situated below distal end of the ligamental groove. Anterior lateral teeth rather distant from cardinal teeth. Anterior adductor muscle scar elongate, posterior scar roughly quadrate and with a distinct ventral expansion. Pallial sinus very deep, extending forwards to a short distance of anterior adductor scar.
