 total length (with the caudal), that of the snout five times and a half ; 

 upper jaw a little longer than broad. The diameter of the eye is 

 rather less than the width of the interorbital space, and one-half of 

 the length of the postorbital part of the head. Vertex flat. The 

 dorsal fin commences before the anal ; ventrals inserted in the an- 

 terior half of the fourth sixth of the total length. Caudal deeply 

 emarginate. Sides with a silvery band.

The length of the entire head is contained thrice in the total 

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

 the upper jaw) five times. The triangular part of the upper jaw, 

 formed by the intermaxillaries, is much broader than long. The 

 diameter of the eye equals the width of the interorbital space, and is 

 two-thirds of the postorbital part of the head. The root of the 

 ventral fin is midway between the base of the caudal and the eye. 

 Dorsal and anal fins scaly ; the former longer than the latter. Caudal 

 fin deeply forked, the central rays being somewhat shorter than the 

 eye. Back dark greenish, sides with a well-defined silvery band 

 not quite so broad as a scale.

 twice and two-thirds in the total (without caudal), the length of the 

 lower jaw (beyond the extremity of the upper jaw) four times and a

 maxillaries is much broader than long. The diameter of the eye 

 equals the width of the interorliital space, and is two-thirds of the 

 postorbital part of the head. The root of the ventral fin is midway 

 between the base of the caudal and the eye ; pectoral longer than 

 the head (without snout). Dorsal and anal fins scaleless ; the former 

 rather longer than the latter. Caudal fin emarginate, the central
