 in head; snout 0.8 eye; interorbital space 1.25 in eye; rostral barbels 

 0.6 eye, maxillary barbels 0.2 eye; maxillary reaching vertical from 

 anterior edge of eye; lower jaw slightly longer, its postsymphyseal

Fins : Origin of dorsal fin midway between posterior edge of orbit 

 and base of caudal fin, rays ii,7, longest ray 1.2 in head; caudal fin 

 longer than head, forked for half its length, the lobes pointed; anal 

 fin arising under base of fourth branched dorsal ray, its rays ii,10, 

 longest ray 1.8 in head; ventral rays i,7, 1.4 in head, reaching anal 

 opening; pectoral rays i,10, 1.3 in head, not reaching base of ventrals. 



Coloration : Silvery ; a black line along side from a point over pec- 

 toral fin to base of caudal; dorsal rays basally dusky green; other 

 fins plain. 



Type.— The type (M.C.Z. No. 35524), 7.5 cm. long, was collected 

 by the Harvard Primate Expedition April 27, 1937, at Chiengmai,
