 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 lieight 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 6-| 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 prcnuixillary ; the upper jaw reaches to the vertical through 

 the middle of the orbit. Acute villiform teeth laterally in the 

 premaxillai 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. Pseudobranchiffi present. 



Head naked ; body covered witii rather large, imbricating, 

 cycloid scales. Lateral line traversing the middle of the 

 body uninterru|)tedly, 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 uiuirticulated, 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. 'J'he anal begins nearly a head-length
