MATERIAL EXAMINED. — The type material and: BENTHAUS, stn DW 1926, Banc Président Thiers, 24°38.2’S , 146°00.8’W , 50-90 m , 1 lv ( Fig. 4A, B ). DISTRIBUTION. — Indo-West Pacific ( Kay 1979 ). From Izu Peninsula ( Japan ) to tropical Indo-Pacific ( Tsuchiya 2000 ), “intertidal to 20 m , on Acropora , Scleractinia [ sic ] and other corals” ( Higo et al . 2001: 216 ). Coral Sea, New Caledonia and Loyalty Islands , empty shells intertidal to 57 m ( Oliverio 2008b ). Austral Islands , living in 50- 90 m . REMARKS This is a common shallow water species throughout the Indo-Pacific, found mainly on Acropora -like corals. The record of a single specimen (dredged by RV Alis ), notwithstanding the relevant collecting effort by the land based RAPA 2002 workshop, indicates a scarcity of this species.
