DISTINGUISHING FEATURES.— 1D II,9–10 (rarely 8 or 12); P i18–i22; V 8–9; inner GR-I 9–12 total; scale rows below midbase 1D 6.5–9, below 2D 7.5–11; lateral line scales over distance equal to predorsal length 35–42; pyl. caeca 15–16 (13–14 fide Iwamoto and Anderson 1994:18). Snout
length 28–32% HL; preoral length 18–29%; interorbital 18–24%; orbit 29–31%; orbit to preopercle 34–40%; suborbital 12–14%; upper jaw 27–33%; barbel 9–18%. Body relatively slender, compressed; head about 5–6 in TL; snout conical, protruding well beyond mouth, with stout tubercles at tip and lateral angles; suborbital ridge sharp and beset with stout modified scales; underside of head almost completely naked, with large pores; body scales densely covered with long, needle-like spinules in parallel to convergent rows. Long spinous ray of 1D 96–156% HL, serrations widely spaced. Anterior dermal window of light organ prominent, situated between V-fin bases. Color overall light brown, blackish over abdomen; gill cover, gill membranes dark; mouth and gill cavities black; 1D blackish proximally, pale to whitish distally, V black, P and A dusky. Attains about 320 mm TL.
DISTRIBUTION.— A widespread Indo-Pacific species; s. Japan through Philippines, Indonesia, s. to New Caledonia region, w. coast of Australia, and s. Africa, in 316–1000 m . Our Taiwan specimens were taken in 316–731 m.
