Nom indig. : Seluwang (river Bongan), Seluwang howong 

 (river Howong). — var. fasciata: Sebetelo (river Kajan). 



Habitat: Borneo (rivers Bongan!, Howong! and Kajan!). 



Note: This species is very near to R. tawarensis M. Web. 

 & de Bfrt. and R. leptosonia Blkr. It is characterized by the 

 position of the dorsal fin, the origin of which is farther behind 

 the origin of the ventrals, than in the two above named species, 

 its caudal peduncle is higher and the height of the anal is more.

D. 2.7; A. 3.5 ; V. 1.7; P. I.I 5; L. 1.29 — 3 3 (with caudal scales). 



Height about equal to head, more than 4, more than 5 

 in length with caudal. Eye 3.5 — 3.7; shorter than snout, about 

 1^/2 in interorbital space. Cleft of mouth ascending, its anterior 

 end in the level of the upper border of the pupil, posteriorly 

 not reaching vertical through frontborder of eye. Origin of 

 dorsal slightly before or in the middle between snout and 

 last row of caudal scales, nearly opposite to or slightly behind 

 origin of ventrals, opposite to i ith lateral scale, 12 scales in front 

 of it. The dorsal is truncate, its height less than that of body. 

 Anal concave, third ray the longest, its height one third shorter 

 than that of dorsal. Ventrals slightly shorter than pectorals, not 

 reaching anal, their origin in fullgrown specimens one eyedia- 

 meter nearer to anal than to operculum. Pectorals much shorter 

 than head. Least height of caudal peduncle more than i '/j in 

 its length to the hindermost row of scales. Seven rows of scales 

 between the lateral lines counted over the back of the middle 

 of the caudal peduncle. The longest rays of the caudal more 

 than twice the length of the shortest ones. Brown above, 

 yellowish below, separated by a bluish silvery lateral band, 

 with brown underneath. A general silvery hue. A dark line
