 - in transverse series between dorsal and anal, 12 round 

 caudal peduncle. Brown above, silvery beneath ; fins 

 brownish. 



Total length 110 mm. 



A single specimen from the Quanza River at Cunga.

 mouth small, subinferior, its width 1 to £ length of head ; 

 teeth notched, 5-7 in upper jaw, 6-8 in lower ; posterior 

 nostril a little below level of centre of eye ; eye about § 

 length of snout and ^ interorbital width. Dorsal 20-22, 

 its length about | its distance from head, originating above 

 4th to 6th ray of anal. Anal 25-28, a little longer than 

 dorsal, nearly equally distant from base of ventral and from 

 base of caudal. Pectoral pointed, £ to ^ length of head, 

 reaching base of ventral. Caudal densely scaled in the 

 basal half, with obtusely pointed lobes. Caudal peduncle 

 3 to 3i times as long as deep, as long as head. 71-80

 vertical bar between anterior part of dorsal and anal.
