), elongate, mytiliform, somewhat flattened laterally with a moderate keel. Shell surface with broad radial ribs crossed by irregularly spaced major commarginal lines interspersed with fine, closely spaced minor commarginal lines. Radial ribs number about 26 dorsal to keel, sometimes bifurcating towards the shell margins; finer, closely set ribs are present ventral to the keel, becoming obsolete towards the anterior, but reappearing again at the anterior end as broad but closely spaced radial ribs. Umbones subterminal. Periostracum green at the posterior half of the shell and along the posterior valve margins, while the anterior half of the shell is dark brown. Byssal hairs absent. Interior of shell tinged with purple; inside margins of dorsal and anterior regions crenulate, which correspond to the terminations of the radial ribs on the shell surface. The ligament is robust, relatively wide, resilium pits absent. The inside shell margins immediately posterior to the ligament bears about 10 crenules, whilst those at the anterior margin ventral to the umbones has 17 strongly impressed denticles that become smaller towards the posterior. The anterior adductor muscle scar traces a shallow arc just inside the antero-ventral edge of the shell. The posterior adductor muscle scar is relatively large, ovatecircular in shape (diameter about

Shell microstructure comprising a thin (10–15µm) subperiostracal homogeneous layer and thicker 250–300 µm nacreous layer. A simple prismatic myostracum occurs as the innermost layer. Shell is predominantly aragonitic (98.8% w/w) with presence of trace amounts of calcite (0.8%). Animal with very short labial palps (about ¼ length of ctenidium) with about 22 folds. Upper edges of the ascending lamellae of outer demibranchs attached to the inside surface of mantle about ⅔ way dorsally. Upper edges of ascending lamellae of inner demibranchs attached to roof of mantle cavity. Plicate glands absent. Foot elongate, muscular. The posterior pedal/byssal retractor muscle complex is distinctly separated into two regions, comprising an anterior set that is barely split into two equal bundles near the shell attachment region, and a posterior set with two equally elongate bundles that is each subdivided into two smaller bundles at the attachment region. The pericardium is located between the anterior and posterior sets of the posterior byssal retractor muscle complex (Category 3 of
