Origin of dorsal about equidistant from the snout and the base of 

 the caudal, or slightly nearer the snout, its anterior rays 3.4 in the 

 length; caudal sharp, lobes equal and as long as the head; anal not 

 emarginate, short, its longest ray equalling length of ventrals or the 

 head without snout and half the eye. Origin of anal slightly in ad- 

 vance of vertical from last dorsal ray. 



Scales regularly imbricate, below the lateral line from above the 

 ventrals posteriorly they are deflected or decurrent to the anal. Anal 

 sheath, a single row of oblong scales decreasing in size progressively 

 towards the last rays; a short axillary scale. Lateral line gently de- 

 curved throughout its length. 



Silvery; a lateral streak of bright silver from operculum to caudal; 

 a single round black humeral spot; a horizontally oval spot at the end 

 of the caudal peduncle.
