MATERIAL EXAMINED. — Tubuai. BENTHAUS, stn DW 1961, 23°21’S, 149°34’W, 470-800 m, 1 rv.

Rurutu. BENTHAUS, stn DW 1995, 22°29’S, 151°22’W, 212-450 m, 1 fragment.

DISTRIBUTION. — Eastern South Africa, Mozambique, Madagascar, Réunion, Thailand, southern Japan, China, Philippines, Indonesia, northwestern Australia, Papua New Guinea, New Caledonia, Fiji, Line Islands, Society Islands and Tuamotu ( Dijkstra 1991: 45; 1998: 21; Dijkstra & Kilburn 2001: 280; MNHN, coll. HD, unpubl. data). Depth range 18-120 m (alive) (unpubl. data, coll. HD). Now also Austral Islands (new record), only single valves at 212-470 m depth.

REMARKS

The type locality is Réunion Island, and the type material appears to be lost ; it is not in MNHN, where most Deshayes types of Recent molluscs – formerly in École des Mines – are currently lodged. The present specimens from the Austral Islands are morphologically indistinguishable from modern material from Réunion in MNHN .
