Pecten cooperi E. A. Smith, 1903: 621 View in CoL , pl. 36, figs. 15–18. Type locality: Felidu Atoll , Maldive Islands, 2– 64 m.

Description: Shell up to ca. 20 mm high, adult height usually 10–15 mm, moderately convex, inequilateral, auricles very unequal, umbonal angle ca. 85°–95°, ribbing of valves different. LV with 9–11 prominent radial costae and 1–3 interstitial secondary riblets, one of which is dominant. Ribs with irregular lamellae, sometimes slightly noduliferous. Interspaces covered with concentric lamellae.Anterior auricle much larger than posterior (ca. 3:1), sculptured with 4–6 noduliferous and lamellate radial ribs, posterior auricle nearly smooth. RV with 9–11 prominent radial costae, divided into 3– 4 lamellate secondary riblets, interspaces smaller than costae and concentrically lamellated. Anterior auricle sculptured with 5–7 noduliferous and/or lamellated radial riblets, less prominent than on LV. Posterior auricle nodulous. Hinge line straight. Byssal fasciole relative broad, byssal notch deep. Active ctenolium with 3–5 teeth on suture. Resilifer black and elongately oblique-triangular. Outer ligament brown.Auricular crura well developed. Inner surface of both valves glossy white and somewhat plicated, more prominent near ventral margin. Colour creamy with pink or brown maculations, LV slightly more strongly coloured.
