Cryptopecten alli Dall, Bartsch & Rehder, 1938: 93 View in CoL , pl. 23, figs 1–4, 7; Abbott & Dance, 1982, 308, holotype figured. Type locality: S coast of Oahu, Hawaii, 436– 461 m.

Cryptopecten complanus Wang, 1983: 402 View in CoL , 405, figs 1.1–7. Type locality: East   GoogleMaps China Sea, 31°05'N, 128°00'E, 147 m.

Description: Shell small, height to ca. 25 mm (average ca. 20 mm), thin, inflated, suborbicular, somewhat oblique, RV slightly more convex than left, inequilateral, auricles unequal, umbonal angle ca. 100–110°. Prodissoconch ca. 230 µm in height.

Both valves sculptured with 17–20 squamose, bivesicular costae (commonly 18– 19). Interstices commonly narrower than costae, commarginally lamellate (finer on RV). Anterior auricle slightly larger than posterior one, with 2 prominent radial riblets and 2–4 interstitial ones; posterior auricle with one strong radial riblet and 3–5 smaller ones between disc margin. Inner surface strongly plicate. Hinge line straight. Byssal fasciole moderately small, byssal notch rather deep. Active ctenolium with 4–5 teeth on suture. Resilifer elongate triangular. Colour variable, commonly reddish brown with pale oblique or zigzag stripes or blotches, sometimes uniform yellow or purple.

Type material (all seen by HD): P. (C.) bullatus : holotype ZMA Moll. 3.12.006, 2 paratypes ZMA Moll. 3.12.007. C. alli : holotype USNM 173.194 About USNM . C. complanus : holotype IOAS M11.072 , paratype IOAS M11.073 .

Regional data: Natal: off Amanzimtoti, 160–170 m, medium sand, dead (D1485).

Distribution: Throughout the W, SW and central Pacific, also known from the W Indian Ocean, south-western limit southern KwaZulu-Natal.

Habitat: Sublittoral to bathyal depths, living between coral rubble on sandy substrates.

Remarks: The convexity and sculpture of C. bullatus vary with its bathymetric range and geographic distribution. For further discussion see Hayami (1984: 98), Wagner (1989: 61) and Dijkstra (1991: 36).
