General Description

From Boulenger 1909, pp. 121-122

Depth of body equal to length of head, 3 4/5 to 4 times in total length. Upper profile of head descending in a strong curve; snout much prolonged, tubiform, strongly compressed, curved downwards, its length 2 to 2 1/3 times postocular part of head, and 3 1/2 to 7 times its least depth, which nearly equals diameter of eye; latter 2/3 interorbital width; lower jaw with a compressed dermal appendage about as long as eye; teeth conical, 5 in upper jaw, 4 in lower. Dorsal 27–31, originating above 6th or 7th ray of anal, its length 1 1/2 to 1 3/4 times in its distance from head. Anal 31–35, nearly equally distant from base of ventral and base of caudal. Pectoral obtusely pointed, 1/2 length of head, ventral 1/3 or rather less; pectoral extending beyond base of ventral. Caudal scaled, with pointed lobes. Caudal peduncle 3 to 3 1/2 times as long as deep, 1/2 to 2/3 length of head. 75–85 scales in lateral line, 18–21 / 30–32 in transverse series on body, 20–23 / 20–23 in transverse series between dorsal and anal, 16 or 18 around caudal peduncle. Brownish, with a rather indistinct darker vertical band between dorsal and anal.

Total length 380 mm.
