Umbones subcentral, prominent, on top of a well-developed trigonal cardinal area which is engraved by oblique, chevron-shaped grooves and covered with a black external ligament. Outer sculpture of numerous radial riblets and concentric threads forming a fine reticulation. Periostracum conspicuous, velvety. Hinge elongate, straightish dorsally and weakly arched ventrally, bearing a series of transverse, diverging outward teeth, and rather long, subhorizontal teeth at both ends, at least in adults. Interior of shell porcelaneous. Two subequal adductor muscle scars; inner margin of posterior scar on a projecting shelf. Pallial line without a sinus.
