Type data. Ostrea striatula Linnaeus : lectotype (pr: H 61 mm, W 65 mm) UUZM [not registered], designated by Dijkstra (1999: 396, figs 10E–F). Type locality: “ O. Indico ” [Indo-West Pacific].

Pecten macassarensis Chenu : lectotype (lv: H 41 mm, W 41 mm), illustrated by Chenu (1845: pl. 39, fig. 4c), herein designated. Type locality: Unknown.

Comments on type data. During visits by the first author in 1989 and 1991 to MNHG, Dr Y. Finet and he could not trace the type material of Pecten macassarensis in the Delessert collection. This material is probably lost. Unfortunately, a description of P. macassarensis was never published, but the figures are clear and determinable.

Description. Shell up to c. 50 mm high, solid, circular, moderately inflated, right valve slightly more convex than left, inequivalve, equilateral; auricles equal in shape and size on left valve, unequal in size and shape on right valve; umbonal angle 105–120°; colour highly variable, blotched with cream, red, brown, orange or pink and paler dots or streaks; right valve paler or whitish; interior yellowish or reddish yellow.

Both valves sculptured with 16–19 evenly spaced, low radial plicae, somewhat broader on right valve than on left. Interspaces and plicae of left valve equal in width; interspaces of right valve each narrower than one plica. Closely spaced commarginal lamellae on disc (more closely arranged in interspaces than on plicae) and auricles, radial riblets very weak in early growth stage on auricles. Dorsal margin of left valve straight, of right valve more declined. Internal rib carinae prominent near ventral margin, weaker near muscle insertion. Resilifer narrowly triangular. Hinge teeth well-developed. Byssal notch shallow; ctenolium weak in juveniles, lacking in adults.

Habitat. Living free (not byssally attached to substrates) from the intertidal zone to 60 m on the continental shelf, in colonies on soft sediment (sand and/or mud).

Distribution. Amami Islands ( Japan) southwards to tropical West Pacific, in 10–20 m (Hayami, 2000: 905); Philippine Islands , 20–25 m (Springsteen & Leobrera, 1986: 328), Raines (2010: 598); South China Sea, Sulawesi, Moluccas, intertidal– 20 m (Bernard et al., 1993: 50); Indonesia, offshore, common (Dharma, 1992: 84); Gulf of Thailand, 16–22 m ( Swennen et al., 2001: 74); northern Western Australia (Lamprell & Whitehead, 1992: [26]). Maximum depth range intertidal to 60 m.

Remarks. Hedley (1918b: 265) recorded a single valve of Annachlamys striatula (as Pecten macassarensis ) from the Buccaneer Archipelago, northern Western Australia, and Lamprell & Whitehead (1992: [26]) repeated this distribution. Although this species is quite common throughout the tropical southwestern region of the West Pacific and suitable habitats for it occur in tropical northern Australia, we have not seen material of Annachlamys striatula from Australia.
