DISTRIBUTION. — Norfolk Ridge , live in 516-569 m, shells in 532-601 m.
DESCRIPTION. — Shell up to 5.1 mm long, translucent white. Maximum diameter at centre of shell. In lateral view, ventral side of caudal region exhibits a regular, pronounced, long curve, dorsal side has an alternating slightly concave and convex outline. Dorsal view fusiform. Apex simple, section slightly oval, dorsoventrally compressed. Preapical callus thin, at about 1/4 shell length from aperture. Lumen oval dorsoventrally. Mouth slightly laterally compressed, oblique.
Measurements of holotype: L 5.1, W 1.0-0.9, mouth 0.51-0.46, w 0.40-0.35.
REMARKS. — The main distinctive characters of Cadulus deschampsi are its fusiform shape and the length of the posterior 1/3 of the shell, which is longer than in most similar species. It is somewhat similar to C. simillimus Watson, 1879 , but the new species is smaller and less swollen. Three of the specimens show naticid perforations in the side of the apex, demonstrating active naticid predation in the locality.
ETYMOLOGY. — Named after Guy Deschamps, a volunteer at MNHN, who has sorted numerous bottom samples for micromolluscs over almost 20 years.
