DISTINGUISHING FEATURES.— 1D II, 8–9; P i17–i18; GR-I (inner) 6–8 total; scales below midbase 1D 5.5–7.5, below 2D 5.5–7.5; pyl.caeca 42–48. Snout long, narrow, pointed in lateral view, tip rounded, length 39–46% HL, anterolateral margin of snout completely supported by bone; orbit 16–19% HL; upper jaw 26–29% HL. Nasal fossa scaly, underside of snout naked, but finely scaled posteriorly on head; spinules on body scales in 5–8 sharp, slightly divergent ridge rows. Light organ short, Group II of Iwamoto (in Cohen et al. 1990); anus removed from A origin. Ground color brown, bluish on belly and halfway onto chest; underside of head, mouth, and gill cavities dark; fins generally dusky to blackish. Attains more than 850 mm TL.
DISTRIBUTION.— Apparently endemic to Taiwan (NET, SWT, SCS). The species is most abundant in 300–400 m off s. Taiwan and 400–800 m in ne. Taiwan.
REMARKS.— Shen et al.’s (1993) record of C. tokensis was a misidentification of C. leptorhinus. The species is abundant in the bycatch of the deepwater trawl fisheries off Da-xi (NET). It is most closely similar to the Philippines species C. macrorhynchus Smith and Radcliffe, 1912 in having a notably long snout, long jaws, relatively long barbel, and similar light organ. The main differences between the two species lie in C. leptorhinus having the underside of snout naked and having a slightly shorter snout (preoral length 35–40% HL cf 40–45%).
