MATERIAL EXAMINED (9 spec.).— NET: ASIZP 61336 (4, 158–211 TL), Da-xi; ASIZP 65796 (1, 176 TL), Da-xi; ASIZP 66336 (1, 221 TL), Nan-Fang-Ao; CAS 56041 (1, 152 TL), Dong-gang; NMMST-P (1, 172 TL), Hsiao-liu-chiu. Other specimens: ASIZP 67947 (1, 190 TL), Aurora, 269– 277 m.
DISTINGUISHING FEATURES.— 1D II, 8–10; P i15–i19; GR-I (inner) 9–12 total; scale below midbase 1D 3.5–4.0, below 2D 4.5–5.0; pyl.caeca 7–13. Snout sharply pointed, length 31–37% HL, anterolateral margin snout incompletely supported by bone; orbit 24–29% HL; upper jaw 28–34% HL. Nasal fossa and broad areas anteriorly and laterally atop snout naked; underside of head naked except along anterolateral margin of snout where scales broadly overlap edge; underside of head covered with unpaired black papillae; spinules on body scales short, broad based, in irregularly quincunx order. Light organ long, extends forward to near isthmus, Group IV. Dorsum brownish gray with irregular darker blotches, remainder of body silvery; chest and area around periproct and anal-fin origin blackish or dark; fins dusky; median nasal process black; mouth and gill cavities white; gular and branchiostegal membranes heavily peppered, but underside of snout covered with hair-like black papillae. Attains at least 284 mm TL.
DISTRIBUTION.— Southern Japan, East China Sea, ne. Taiwan, and Philippines, in depths of 100–650 m. The Philippine specimen represents the southernmost record of the species.
REMARKS.— Coelorinchus kamoharai is closely similar to C. multispinulosus, C. formosanus, and C. longissimus, but differs from them in its body markings; in addition, C. multispinulosus has slender, dense scale spinules on body scales and sparse, paired papillae under the head, C. formosanus has scales posteriorly on underside of head; and C. longissimus has scale spinules arranged in definite rows, small scales on nasal fossa, and underside of snout almost immaculate. Five paratypes (FAKU 1593–1596 and 2496) were rediscovered by one or us (NN) from the FAKU collection.
