Magilus antiquus ( Montfort, 1810) ( Fig. 11F, G )

Magilus antiquus Montfort, 1810: 43 , pl. 11.

TYPE MATERIAL. — Probably lost.

TYPE LOCALITY. — Undetermined (“East Indies”).

MATERIAL EXAMINED. — Rimatara Is., BENTHAUS, stn DW 2020, 22°37’S, 152°49.1’W, 920-930 m, 1 dd, 1 juv dd. Hiri Bay, ATELIER RAPA 2002 , stn 9, 27°37.3’S, 144°22.2’W, 3-24 m 2 dd (still inside the unidentified faviid colony) ( Fig. 11F, G ).

DISTRIBUTION. — Indian Ocean, Eastern Arabia “insinuated in stony corals” ( Bosch et al. 1995). Tropical Indo-West Pacific, living in cavities within faviine scleractinian corals ( Massin 1982). New Caledonia and Loyalty Islands, empty juvenile shells in 40-350 m, possibly having drifted from an original shallower habitat ( Oliverio 2008b). Austral Islands, two empty shells in 920-930 m, certainly drifted from shallower habitat, and two empty shells in 3- 24 m.

REMARKS

Specifically focused sampling is necessary to obtain adults from within coral.
