Geographical distribution and bathymetry

Japan to Philippines, Solomon Islands and Australia (Queensland). Also present in the Andaman Sea, off Myanmar. In New Caledonia present in Loyalty Islands, Norfolk Ridge, Grand Passage area and Coral Sea, typically at depths between 200–400 m, but also found below 500 m.

Remarks

Biconical shell, moderately large to large (maximum shell length 113 mm), with a very high and stepped spire. Protoconch multispiral of about 3 whorls ( Fig. 89L View Fig ). Last whorl white with irregular brown axial lines and brown spiral bands on each side of center, overlaid with spiral rows of alternating white spots and brown axial dashes. Radular tooth ( Fig. 89M View Fig ) with the anterior section shorter than the posterior section. Tooth serrated with 5–6 denticles arranged in one row becoming 2–3 rows below, ending on a very large pointed, tusk-shaped cusp. Barb very large, with the shape of a sickle. Blade reduced, indistinct, restricted to the apical portion (25–30% of the anterior section of the tooth). Basal spur absent or vestigial. Base rounded. The sequenced specimens of C. (T.) excelsus form a well supported clade within Turriconus ( Fig. 2 View Fig ).
