Shell moderately strong and inflated, with a variable shape, generally relatively short for its height, elongate-subquadrate in outline. Umbones low, markedly anterior to midline of shell. Posterodorsal margin feebly arched and gently sloping, meeting the rounded and high posterior margin at an obtuse angle. Anterodorsal margin shorter, straightish to slightly concave, slanting obliquely towards the acutely rounded anterior margin. Ventral margin regularly and broadly rounded. Lunule smoothish, about twice as long as wide, with fine peripheral groove. Escutcheon asymmetrical, more distinct in left valve. Outer sculpture both concentric and radial, more pronounced anteriorly and posteriorly, giving a distinctly latticed and granulated characteristic pattern. Hinge with 3 cardinal teeth at each valve, but without lateral teeth. Pallial sinus deep and rounded, longer than high, nearly attaining mid-length of valves. Internal margins smooth.
