Equivalved, inequilateral, subovate, cordate or subtriangular, with inconspicuous umbones, straight hinge line and obliquely extended posterior end semielliptical, spatulate or acuminate in outline. Hinge line 50-80 percent of length, forming with straight or curved posterior margin obtuse angle (β), which may be sharp or rounded, never auriculate, dorsal and ventral margins converging toward anterior end which may be quite acute, umbones small, situated well forward but not terminal, rising little or not at all above level of hinge line in type subgenus. Shell substance thin, ornament of concentric growth lines, folds or rugae, subgenera showing in varying degrees radial striation of delicate straight lines probably comprising trace of prismatic or periostracal structure shown through worn periostracum.
