which is two-ninths of the total (without caudal fin). The distance 

 of the occiput from the front margin of the upper jaw is less than 

 one-half of its distance from the origin of the dorsal fin. The dia- 

 meter of the eye is as long as the snout, and a quarter or a little 

 less than a quarter of the length of the head ; length of the man- 

 dible much more than the least depth of the tail. Pectoral as long as 

 the head (without snout). There are seven longitudinal series of scales 

 between the lateral line and the root of the ventral fin.

The height of the body is one-fourth of the total length (without

 occiput from the front margin of the upper jaw is one-half of its 

 distance from the origin of the dorsal fin. Eye large, considerably 

 longer than the snout, and two-sevenths of the length of the head. 

 Length of the mandible more than the least depth of the tail. Pec- 

 toral a little longer than the head (without snout). There are seven 

 longitudinal series of scales between the lateral line and the root of 

 the ventral fin.
