729-753 m, 1 spm; stn CP 1346, 17˚20’S, 178˚32’E, 673-683

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).
