DISTRIBUTION. — Southern Cooks, western Austral Islands, Society Islands, Tuamotu, and Pitcairn Group, “alive under and near corals” in 12-17 m [40-55 ft] ( Rehder 1985: 99), empty shells from Austral Islands in 15-25 m (paratypes) and 90-680 m (BENTHAUS).

REMARKS

The protoconch (tip missing) of a juvenile from Anaa (Tuamotu, J. Tröndlé coll., La Force) is of 2.8+ whorls, 700+ µm high and 720 µm wide at the base, with 2 equally strong spiral keels, sculptured by a series of subsutural prosocline threads and a series of similar threads over each keel. General shape, approximate number of whorls (c. 3) and size are confirmed by the examination of the eroded protoconch in the juvenile shell from Banc Arago (BENTHAUS stn DW 1977).

Only during the BENTHAUS dredging, were specimens of this shallow water species recovered. I have also examined the type material and can confirm the morphological homogeneity of the entire type series, including the paratypes from western Austral Islands. The records of C. latilirata from Austral Islands are congruent with the hypothesized range ( Rehder 1985: 98, fig. 4) centered in French Polynesia, yet excluding Rapa , in the southernmost Austral Islands. It is a shallow water species, thus the deepest records (BENTHAUS) are likely due to drift from shallower habitat.
