Geographical distribution and bathymetry

New Caledonia: Norfolk Ridge, Grand Passage area, Loyalty Ridge and Coral Sea (Lansdowne and Capel Banks), at depths between 100 to 300 m. This species can be considered endemic.

Remarks

Shell medium-sized to moderately large (maximum shell length 62 mm). Conical to ventricosely conical, with a low to moderate spire of deeply concave outline. Protoconch multispiral ( Fig. 71L View Fig ) of more than 3 whorls. Last whorl patterned with spiral rows of orange to reddish brown blotches alternating with white. Patternless white shells do exist ( Fig. 71F View Fig ). Radular tooth ( Fig. 71M View Fig ) with the anterior section slightly shorter than the posterior section. The tooth is serrated with 8–10 denticles arranged in one single row. Elongated terminating cusp present. Barb well marked. Blade rounded, covering about 30% of the anterior section of the tooth. Basal spur on top of a rather large base. The specimens sequenced form a clade sister to C. (P.) kuroharai . This species, endemic to the EEZ, is one of the most characteristic representatives of the New Caledonian deep-water cone fauna, and it is fairly common in the localities where it has been sampled.
