TYPE MATERIAL. — Purpura bulbiformis : not found. — Purpura gibbosa : 3 possible syntypes BMNH 1984102 , none of which matches the original illustration (K.M. Way pers. comm.), 1 figured by Kosuge & Suzuki (1985: pl. 47, fig. 2) . — Coralliophila cantrainei: Kosuge & Suzuki (1985: pl. 47, fig. 1) figured an alleged “ syntype ” from MNHN ;

actually there are 4 specimens “ ex. d’auteur ” (determined by the author - Montrouzier - yet not type material) in MNHN; the holotype should be in the Musée de Bordeaux . — Coralliophila elaborata : lectotype (“type”, Kosuge & Suzuki 1985, pl. 37, fig. 8) BMNH 1982057 /1, 2 paralectotypes BMNH 1982057 /2-3 .

DISTRIBUTION. — Throughout the Indo-West Pacific. Tropical Pacific, intertidal ( Cernohorsky 1978). Kermadec Islands, New Zealand, with hermatypic corals (Brook 1999: 453). From the Coral Sea , New Caledonia and Loyalty Islands, live in 4-32 m, empty shells down to 56 m, with an empty shell from Loyalty Ridge in 200 m (probably drifted from shallower habitat) .

REMARKS. — Protoconch of 3.3 whorls, 700 Μm high and 720 Μm wide at the base. Protoconch-I of 1 whorl, sculptured with pustules over the entire surface. Protoconch-II of 2.3 whorls, with 2 spiral keels (the abapical starting on the second protoconch whorl, the adapical starting on the third), sculptured by a series of subsutural prosocline threads and a series of similar threads over each keel; the threads tend to fuse, giving rise to collabral riblets. A diffuse granulation is present in the interspaces.
