Geographical distribution and bathymetry From Japan to Taiwan , Philippines and Solomon Islands . In New Caledonia present in the Norfolk Ridge and Grand Passage area, Loyalty Islands and New Hebrides Arc (Hunter Island), at depths between 200 and 600 m . Also found in the Coral Sea (Lansdowne Bank) Remarks Shell moderately large to large (maximum shell length 100 mm ), ventricosely conical to broadly and ventricosely conical, with a high stepped spire of slightly concave profile. Early spire whorls tuberculated. Protoconch multispiral. Shoulder subangulate to rounded. Color of the last whorl white, with sparse reddish brown dotted spiral lines. Radular tooth ( Fig. 61J ) stout, with the anterior portion much shorter than the posterior section. The tooth is serrated with 20 to 30 minute denticles arranged in multiple rows, ending on a small, pointed terminating cusp. Barb well marked. Blade rounded, covering about 70% of the anterior section of the tooth. Small basal spur on top of the rounded base. In the phylogeny ( Fig. 2 ), the specimens of C. stupa form a clade sister to C . ( K .) darkini . This species is widely distributed in the Western Pacific, but it is rather uncommonly sampled due to its deep-water habitat.
