BAEBUS. 215 



two-thirds to four-fifths the length of the head, reaching or nearly reaching the root 

 of the caudal fin. Pectoral fin a little shorter than the head, not reaching the ventral ; 

 latter below the anterior rays of the dorsal. Caudal fin deeply forked. Caudal 

 peduncle once and a half to once and two-thirds as long as deep. Scales finely 

 striated longitudinally, 28-30 |f, 2J between lateral line and root of ventral, 12 round 

 caudal peduncle. 



The colour is described by Mr. Zaphiro as dark olive above, silvery white beneath, 

 with or without a pale rose wash all over the body ; caudal fin yellowish, with or 

 without red at the end, the other fins greyish, with pale red at the end, or pectoral, 

 ventral, and anal fins reddish ; iris yellow. 



The largest specimen measures 265 millimetres. 



Two specimens from the Metti River, a fast-running stream about 20 yards wide, 

 in Salle, altitude 3500 feet, flowing to the Gudar River, and two from the latter river, 

 a southern tributary of the Blue Nile, altitude 3400 feet, were collected by Mr. P. C. 

 Zaphiro on April 23rd and 24th 1905, and presented to the British Museum by 

 Mr. W. N. McMillan. 



This species should be placed close to B. oreas, Blgr., from the Jerrer River 

 (Havvash system), from which it is distinguished by the lower number of scales in the 

 lateral line. 



6. BARBUS EUMYSTUS. 



(Plate XXXVIII. fig. 1.) 



Boulenger, Ann. & Mag. N. H. (7) xvii. 1906, p. 565. 



Body strongly compressed, its depth equal to the length of the head and nearly one- 

 fourth of the total length. Snout rounded, three times in the length of the head ; 

 diameter of the eye five times in the length of the head, interorbital width three times ; 

 mouth inferior, its width four and a half times in the length of the head ; lips well 

 developed, the lower continuous across the chin and forming a small rounded median 

 lobe ; barbels two on each side, equal, twice and one-third the diameter of the eye, the 

 distance between their bases slightly less than the diameter of the eye. Dorsal fin 

 with IV 9 rays, the free edge strongly emarginate ; last simple ray strong, bony, not 

 serrated, straight, five-sixths the length of the head ; its distance from the praeoperculum 

 equals its distance from the caudal fin. Anal fin with III 5 rays, the longest ray three- 

 fourths the length of the head, nearly reaching the root of the caudal fin. Pectoral fin 

 a little shorter than the head, not reaching the ventral; latter below the anterior rays 

 of the dorsal. Caudal fin deeply forked. Caudal peduncle once and two-thirds as long 

 as deep. Scales finely striated longitudinally, 31 |f , 2 J between lateral line and root of 

 ventral, 12 round caudal peduncle.
