midway between the ej^e find the base of the caudal. Dorsal and 

 anal fins scalj' ; the former a little longer than the latter. Caudal fin 

 emarginatc, the central rays being much longer than the eye. Back

The length of the entire head is but little less than one-half of the 

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

 mity of the upper jaw) nearly one-third. The triangular part of the 

 upper jaw, formed by the intermaxillaries, is very convex and mirch 

 longer than broad. The diameter of the eye is less than the width 

 of the interorbital space, and contained once and two-thirds in the 

 length of the postorbital part of the head. The root of the ventral 

 fin is much nearer to the base of the caudal than to the axil of the 

 pectoral. Dorsal and anal fins scaleless, the former longer than the 

 latter. Caudal fin emarginate, the central rays being much longer 

 than the eye. Sides with a well-defined silvery band as broad as a 

 scale.

Body compressed, its depth being one-eighth of the distance be- 

 tween the extremity of the upper jaw and the root of the caudal. 

 The length of the entire head is contained twice and one-fifth or 

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

 lower jaw (beyond the extremity of the upper jaw) thrice and two- 

 thirds. The triangular part of the upper j aw, formed by the inter- 

 maxillaries, is longer than broad, convex. The diameter of the eye 

 is less than the width of the interorbital space, and contained once 

 and two-thirds in the length of the postorbital part of the head. 

 The root of the ventral fin is equidistant from the caudal and the 

 extremity of the pectoral. Dorsal fin scaleless; anal scaly; the former 

 much longer than the latter. Caudal fin deeply forked, the central 

 rays being longer than the eye. Sides with a silvery baud, which is 

 broader than a scale ; mandibulary fringes broad, deep black.
