Periostracum thick, dull brown, fi brous. Shell colour creamy or greyish white. Sculpture of many irregular, rounded, commarginal lamellae or ridges. Lunule short, heart-shaped, symmetrical. Hinge plate thin, edentulous and smooth. Ligament largely internal; inner fibrous layer of ligament extends laterally and posteriorly into the valve forming a thick, triangular
pad within narrow ligamental nymph. Anterior adductor muscle scar relatively broad and short, blunt ended; diverges from pallial line at an angle of 30-34°. Pallial line entire, narrow. Secondary pallial muscle scars extend from the junction of the
pallial line and anterior adductor scar to just ventral of the posterior adductor scar (Fig. 3A).
