DISTINGUISHING FEATURES.— 1D II, 8–10; P i16–i20; GR-I (inner) 6–9 total; scales below midbase 1D 3.0–4.5, below 2D 3.5–4.5; pyl.caeca 16–23. Snout sharply pointed, length 42–45% HL, anterolateral margin snout incompletely supported by bone; orbit 24–27% HL; upper jaw 23–28% HL. Most of nasal fossa and broad areas atop snout naked; underside of head naked except along anterolateral margin of snout where scales broadly overlap edge; spinules on body scales short, weak, slender in 6–14 parallel to slightly divergent rows. Light organ long, extends forward to near isthmus, Group IV of Iwamoto (in Cohen et al. 1990). Dorsum gray with faint irregular blotches, remainder of body silvery; fins dusky, 1D with blackish membrane behind long spinous ray; median nasal process black; mouth white, gill cavities blackish; gular and branchiostegal membranes heavily peppered; underside of snout clear, mostly lacking melanophores except along outer margins. Attains at least 357 mm TL.

DISTRIBUTION.— Pacific coast of s. Japan from Suruga Bay s. into the East China Sea (Okinawa Trough), ne. Taiwan, the South China Sea off Taiwan, and in the Philippines, in 280–400 m.

REMARKS.— This species is closely similar to C. kamoharai , differing only in the slender scale spinules arrayed in many divergent rows (as compared with short broad spinules in quincunx pattern) and paler, slightly different pattern of blotches on the body.
