Predorsal contour evenly and moderately convex, the Postdorsal contour 

 more or less straight from origin of dorsal to caudal fin; Ventral contour much 

 more convex than dorsal contour, the body axis closer to dorsal than to pelvic fins. 

 Dorsal fin originating nearer to tip of snout than to caudal base. Pelvic fin inserted 

 nearer to insertion of pectoral than to origin of anal. Pectoral fin inserted closer to 

 insertion of pelvic than tip of snout. 



Color. General coloration silvery, especially on the lower half of the head and body; 

 the opercular plates with iridescent or pearlish, metallic reflections. Back dark brownish 

 or bluish gray. Body with dark, longitudinal streaks more conspicuous on back. Humeral 

 spot faint. Tip of snout and mandible dusky. Upper sector of iris dusky. Fins colorless 

 except caudal, which is somewhat pigmented at tip of lobes and along inner margin.
