of caudal than tip of snout, fourth ray spine-like with posterior 

 edge becoming coarsely serrated above, and when depressed 

 first branched ray reaches well beyond others or about ^/g of 

 distance to base of caudal. Anal inserted about midway between 

 origin of dorsal and base of caudal, third ray enlarged but 

 with flexible tip, and depressed fin reaching opposite base of 

 caudal. Caudal damaged. Pectoral low, small, and reaching 

 back for about first fifth of length of ventral. Ventral with 

 first branched ray longest and reaching anal. 



Color in alcohol brown, lower surface paler and with traces 

 of silvery. Each scale on back with a dusky-brown spot, 

 regular in disposition, so that longitudinal series are formed, 

 and several persisting even below lateral line, but lowest much 

 paler than those above. Lower surface of head pale like 

 abdomen. Fins same color, dorsal more or less tinted with 

 dusky, and caudal and anal with brownish. Iris pale brassy- 

 brown". Length 85 mm. [After FowLER, not seen by us]. 



Habitat: Borneo (Baram river). 



We think it probable that this species is only a young 

 specimen of C. siaja. When FoWLER writes: "it agrees with 

 Bleeker's description of Capo'eta enoplos, but his figure (Atlas 

 Ichth. in. 1863, p. 82, PI. (27) 128 fig. 2), agrees with Sumatran 

 examples of Cyclocheilichthys siaja, which may be distinguished 

 by the smaller eye, always less than a third of the length of 

 the head", he overlooked that the quoted figure refers to 

 Barbus enoplos Bleeker, which is a quite different species.
