DISTINGUISHING FEATURES.— 1D II 8–9; P i16–19; GR-I (inner) 6–8 (total); scales below midbase 1D 3.5–5.5, below 2D 4.5–6.5; pyl.caeca 10–15. Snout sharply pointed, 43–50% HL; terminal scute slender, sharp; anterlateral snout margin incompletely support by bone; orbit 22–26% HL, 1.6– 2.2 in snout length; upper jaw 19–24% HL; body somewhat cylindrical, greatest width slightly less than greatest depth. Underside of snout and head naked; nasal fossa naked or sparsely scaled; body scales large, densely covered with 7–15 parallel spinule rows. Second spinous ray of 1D slightly prolonged; rays of 2D well developed, almost as long as opposites in anal fin. Light organ group IV, extends from anus to just behind isthmus. A series of dark saddles on body, anterior two directed obliquely downwards and forward. Attains about 300 mm TL.

DISTRIBUTION.— Originally described from the South China Sea near Taiwan and n. Luzon, but subsequently recorded from Japan (East China Sea), the e. coast of Australia, and the regions around New Caledonia, Vanuatu, and Loyalty Island. It was collected in Taiwan ( NET, SWT) at depths between 236 and 1211 m.

REMARKS.— Specimens from the sw. Pacific show slight differences from those from the n. hemisphere, but we have not been able to tease out any specific characters that would differentiate the populations. The species is most likely to be confused with C. fuscigulus , but that species lacks an elongated 1D spinous ray and has differences in body markings.
