A single specimen was obtained in the Juju Eiver, a stream about 10 yards wide 

 flowing from the hills of Guma to the Didessa Eiver, a southern tributary of the Blue 

 Nile, at an altitude of 2000 feet, by Mr. Zaphiro, and presented to the British 

 Museum by Mr. W. N. McMillan. 



This species is distinguished from the preceding, and from all Barlus of the Nile 

 system, by its longer barbels. In B. gregorii, Blgr., which has also very long barbels, 

 the anterior never exceed once and three-fourths the diameter of the eye.
