DISTINGUISHING FEATURES.— 1D II 8–9; P i18–i19; GR-I (inner) 9–10 total. Scales below midbase 1D 4.5–5.0, below 2D 5–6; pyl.caeca about 27. Snout long, smoothly conical in lateral profile, narrow in dorsal view, its length 41–56% HL, about 2.0 times orbit; anterolateral margin of snout incompletely supported by bone; orbit 20–21% HL, its dorsal margin well below dorsal profile; upper jaw 30–37% HL; nasal fossa scaled anteriorly and ventrally; underside of head fully scaled. Light organ group II of Iwamoto (1990), fossa narrow and short, not extending to pelvic-fin bases. Spinules on body scales sharp, blade-like, in 5–7 slightly divergent, crestlike rows, middle row strongest. Ground color light brown, bluish over abdomen; about 5 prominent saddle marking interspersed with pale narrow bars from trunk to tip of tail; mouth and gill cavity blackish; fins dusky, but pelvic fins blackish except for white outer prolonged ray; margin of A blackish. Attains more than 937 mm TL.

DISTRIBUTION.— Known only from ne. and se. Taiwan in depths of about 100–650 m.

REMARKS.— Coelorinchus sheni appears to be confined to rough-bottom slopes of e. Taiwan where bottom trawls are ineffective; specimens were all captured by longline.
