DISTRIBUTION. — Southeast Africa, Gulf of Aden, Maldive Islands, Japan and Philippines ( Knudsen 1967: 277), Wallis and Futuna and Vanuatu ( Dijkstra 2001: 78); live in 290- 797 m. New record for Fiji. Present material live in 596- 729 m.

REMARKS. — The present material is similar to the type specimens, although somewhat more circular in shape ( type specimens are more elongate and slightly posteriorly oblique), the sculpture on the left valve is slightly more prominent ( type specimens with weaker commarginal sculpture) and the internal ribs are more numerous (present material 11-12 with numerous rudimentary interstitial riblets; type specimens 10 with one or two rudimentary riblets).
