The length of the lower jaw (hcyond the extremity of the upper jaw) 

 is one-fifth of the total (with the caudal) ; the diameter of the eye 

 one-fourth of the distance between the extremity of the upper jaw 

 and of the operculum. Dorsal and anal fins scaly ; the latter shorter 

 and lower than the former ; caudal deeply forked. Sides without 

 silvery band. {Val.)

The length of the entire head is contained twice and three-fifths 

 or twice and a half in the total (without caudal), the length of the 

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

 third. The triang-ular part of the upper jaw, formed by the inter- 

 maxillanes, is as broad as long. The diameter of the eye equals the 

 width of the interorbital space, and is contained once and three- 

 fourths in the length of the postorbital part of the head. The root 

 of the ventral fin is nearer to the caudal than to the axil of the pec- 

 toral. Dorsal and anal fins scaleless ; the former much longer than 

 the latter. Caudal fin deeply forked, the central rays being shorter 

 than the eye. Back dark greenish, sides with a rather indistinct 

 silvery band.

Body compressed, elevated, its greatest dejith being contained five 

 times and one-half in the distance between the extremity of the 

 upper jaw and the root of the caudal. The length of the head is 

 contained twice and a half in the total (without caudal), the length 

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

 and two-thirds. The triangular part of the upper jaw, formed by 

 the inter maxillaries, is much broader than long. The diameter of 

 the eye equals the width of the interorbital space, and is two-thirds
