DISTINGUISHING FEATURES.— 1D II, 8–10; P i15–i19; GR-I (inner) 9–10 total; scales below midbase 1D 3.5–4.0, below 2D.5–4.5; pyl.caeca 19–26. Snout sharply pointed, sides gently convex, tipped with a blunt scute, length 33–45% HL, anterolateral margin snout completely supported by bone; orbit 31–38% HL; upper jaw 23–29% HL. Nasal fossa and underside of head naked; spinules on body scales short, conical, in 8–17 parallel to slightly divergent rows. Light organ short, extends forward only to base of pelvic fins, Group II. Dorsum brownish, belly blackish, rest of body silvery, a large (2 ⁄ 3 orbit diameter) ocellated dark blotch above pectoral fin; underside of head densely peppered; mandibular rami and gill membranes blackish; fins generally dusky, second 1D spine and tips of rays black; mouth and gill cavities whitish. Attains at least 362 mm TL.

DISTRIBUTION.— Off s. Japan, South China Sea, and Taiwan ( NET, SWT) in 200 m to more than 600 m

REMARKS.— Coelorinchus kishinouyei was strangely not recorded by Okamura and Kitajima (1984) from the Okinawa Trough, where it would be expected owing to its presence in s. Japan and Taiwan. In this regard, the distribution is similar to that of C. hubbsi . It is relatively abundant in landings at Da-xi in ne. Taiwan. This highly distinctive species is closely similar to C. jordani , which has a much smaller pectoral blotch and a longer light organ that extends well forward of the pelvic bases and onto the chest. The Taiwan specimens of C. kishinouyei appeared to have a slightly longer snout, smaller orbit, darker overall coloration with little or no silvery, with anal fin black overall, and blotch above pectoral fin more obscure and lacking pale outer ring (i.e., not ocellated).
