The osseous dorsal ray is strong, strongly serrated, its stiff por- 

 tion being as long as the head. Lower Jip tvith a broad, free, con- 

 tinuous fold. Three and a half longitudinal series of scales between 

 the lateral line and ventral fin. The height of the body is a little 

 more than one-third of the total length (without caudal), the length 

 of the head a little more than one-fourth. Snout somewhat pointed, 

 a little longer than the eye ; mouth small. The dorsal fin com- 

 mences vertically above the origin of the ventral, nearly midway 

 between the end of the snout and the root of the caudal ; the first 

 anal ray rather thickened. Caudal fin deeply forked. The outer 

 portions of the vertical and ventral fins deep black.

This species, having the gill-openings a httle narrower than some 

 other species of Barbus, was separated by Dr. Bleeker as a distinct 

 genus. At a later period he appears to have perceived that 

 numerous other Barbels have the gill-openings as narrow as the 

 present ; and dropping this as the principal character, he neverthe- 

 less maintains the genus, but on very insufficient grounds.

 The osseous dorsal ray is of moderate strength, evenly serrated 

 behind, shorter than the head. There are four longitudinal series 

 of scales between the lateral line and the root of the ventral fin. 

 Snout of moderate extent, rather obtuse, with the lower jaw received 

 within the upper. Upper profile of the head concave. The height 

 of the body is contained twice and a half or twice and three-fifths in 

 the total (without caudal), the length of the head thrice and one-fourth 

 or thrice and three -fourths. Origin of the dorsal ^n distinctly be-
