The length of the head is contained twice and three-fourths, that of 

 the snout thrice and four-fifths in the total (without caudal) ; upper 

 jaw broader than long ; the length of the prominent part of the lower 

 jaw is contained from four times and two-thirds to six times and 

 one-third in the total. The diameter of the eye equals the width of 

 the interorbital space, and is two-thirds of the length of the post- 

 orbital part of the head. Pra^orbital longer than high. Dorsal and 

 anal fins ai'e entirely opposed to each other. Ventrals inserted an- 

 teriorly in the fourth fifth of the total lengtli, with tlio inner ray 

 shortest. Caudal deeply forked, the central rays being rather shortei 

 than the eye. Body with a silvery lateral band, (ii/.)

The length of the entire head is a little more than one -third of 

 the total (without caudal), the length of the lower jaw (beyond the 

 extremity of the upper jaw) one-half of the length of the head. The 

 triangular part of the upper jaw, formed by the intermaxillaries, is 

 much broader than long. The diameter of the eye is rnthcr less 

 than the width of the interorbital space, and two-thirds of the length 

 of the postorbital part of the head. Vertex and interorbital space 

 convex. The root of the ventral fin is nearly midway between the 

 front margin o^ the eye and the base of the caudal. Dorsal and 

 anal fins scalek the former a little longer than the latter ; thcv
