 and the belly strongly serrated. In shape the body resembles 

 that of the sea herring; it is compressed, rather low, its depth 

 slightly more than one fourth of the total length without caudal 

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

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

 to the hind margin of the eye; the length of the upper jaw is 

 more than one half the length of head. The origin of the dorsal 

 is over the ninth series of scales, and the length of its base 

 corresponds with 10 rows of scales. The ventral origin is under
