B. 7. D. 49-50. A. 39-40. L. lat. 57-59. L. tr. f. 
Head low, elongate, tapering, its length nearly one fifth of 
the total without, nearly one sixth with, the caudal. Body 
low, elongate, eel-like, its height not quite two fifths the 
length of the head. 
Snout twice as long as the eye, depressed, acute, its tip 
formed by the mandible ; nostrils minute. Eyes superior, 
but with lateral visual axis, separated by a carinated ridge ; 
their major diameter 6J in the head-length. 
Mouth wide, its cleft subhorizontal ; the lower jaw pro- 
jecting nearly half an eye-length beyond the upper and closing 
against a prominent tubercle formed by the enlarged end of 
the premaxillary; the upper jaw reaches to the vertical through 
the middle of the orbit. Acute villiform teeth laterally in the 
premaxillae and in the vomer and palatines ; small canines on 
the premaxillary tubercle and laterally in the lower jaw, 
increasing in size in front, where they stand outside the 
closed mouth. 
Gill-opening very wide, extending almost to the man- 
dibular symphysis ; branchiostegals and suboperculum much 
produced backwards ; gill-rakers on first arch long, close, 
setiform. Pseudobranchiae present. 
Head naked ; body covered with rather large, imbricating, 
cycloid scales. Lateral line traversing the middle of the 
body uninterruptedly, its tubes salient. All the fins with 
their rays slender, and, except in the pectorals, conspicuously 
prolonged. 
The dorsal fin, which occupies almost the entire extent of 
the back, has the first four radial elements weak and flexible 
though unarticulated, and the remainder articulated but 
simple ; the rays gradually decrease in length from the first, 
which is thrice, to the last, which is nearly twice, the greatest 
height of the body. The anal begins nearly a head-length
