Umbo slightly elevated and usually eroded. Ligament very narrow. One shallow hill-like or triangulate pseudocardinal tooth on right valve; left valve with one less developed hill-like to tubercule-like pseudocardinal tooth. End of hinge structure with V-shaped fossette. Anterior adductor muscle scar shallow to well-developed, ovate, contiguous with pedal retractor and anterior protractor muscle scars; posterior adductor muscle scar round, very shallow. Pallial line faint to well-marked, continuous. Umbo cavity moderately deep.</paragraph>
