Description. — The form is the same as in all the fishes of this 

 genus ; the height of the body is one-third or rather less than one- 

 thii'd of the total length, the length of the head three limes and three- 

 fifths ; head longer than high ; snout pointed, of moderate length. 

 Each jaw has two canine teeth in front, the lower of which are sub- 

 horizontal and received between the two upper ones ; the lateral teeth 

 are rather small, especially the posterior ones and those which stand 

 behind the canines. Scales of the operculum nearly as large as those 

 on the body ; the muciferous channels of the scales of the lateral 

 line arc di\ided into five or six branches. Spines of the fins of mo- 

 derate strength and length ; none of the fin-rays produced ; long 

 pointed scales cover the basal half of the caudal membrane.
