DISTRIBUTION. — Southern Japan, China, Philippines, Malaysia, Indonesia, Papua New Guinea, Solomon Islands, Coral Sea, New Caledonia, Fiji and Hawaiian Islands (MNHN, coll. HD, unpubl. data). Depth range 37-183 m (alive) (coll. HD, unpubl. data). Now also Austral Islands (new record), alive at 50-230 m depth.

REMARKS

The present specimens are similar to the holotype from the Moluccas, although the radial lirae are slightly weaker and the colour more creamy. However, examined material from the southwestern Pacific is rather variable in sculpture and colour and the specimens from the Austral Islands fall within this variation range.
