 This species has a few strong and distinct teeth in the jaws, 



the lower jaw strongly projecting, the caudal peduncle stout 



and the belly strongly serrated. In shape the body resembles

and about equal to the length of the head. The eye is large, 



nearly one fourth the length of head; the maxilla extends nearly
