times the length of the lower jaw, its base being as long as the head ; the first 

 ray is minute, and about two thirds as long as the eye ; the second ray is 

 about two thirds the length of the base of the fin, and the subsequent rays 

 rapidly and uniformly decrease in length to the last, which is about twice as 

 long as the first. All the rays except the first are bifid. 



The anal fin is inserted under the second ray of the dorsal : its base is half 

 as long again as that of the dorsal, and nearly one third as long as the body of 

 the fish : its outline resembles that of the dorsal, though slightly emarginate, 

 its longest ray a little longer than the longest of the dorsal, and half as long 

 as the base of the fin. All the rays except the first are bifid. 



Caudal forked, its middle rays less than half as long as the outer rays, 

 equal in length to least height of caudal peduncle. 



Pectoral inserted under the tip of the opercular flap, its length equal to the 

 greatest height of the body. 



Ventral inserted at a distance from the snout equal to twice the length of 

 the head, its length slightly exceeding that of the pectoral, and contained seven 

 times in the standard body length. 



Radial formula : B. VII to IX ; D. I, 11 ; A. I, 16 ; C. 17 ; P. 10 ; V. 5.
