 (Plate XLVII. fig. 6.) 



Barbus miolepis, Boulenger, Ann. & Mag. K H. (7) xii. 1903, p. 532 (non Boulenger, 1902). 

 Barbus wemeri, Boulenger, Proc. Zool. Soc. 1905, i. p. 63. 



Depth of body three to three and a half times in the total length, length of head 

 three and a half to four times. Snout rounded, about four times in the length of the 

 head ; diameter of eye twice and a half to three and one-third times in the length of 

 the head and equal to the interorbital width ; mouth terminal, its width one-fifth to 

 one-fourth the length of the head ; lips feebly developed, not extending across the 

 chin ; barbels two on each side, the anterior a little shorter than the eye, the posterior 

 as long as the eye or a little longer, the space between them not half the diameter of 

 the eye. Dorsal fin with III 7-8 rays, last simple ray not ossified, nearly as long as 

 the head, the border of the fin scarcely emarginate ; origin of the fin equally distant 

 from the end of the snout and from the root of the caudal fin. Anal fin with III 5 

 rays, longest half to three-fifths the length of the head. Pectoral fin acutely 

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

 rays of dorsal. Caudal fin deeply forked. Caudal peduncle once and one-third to 

 once and a half as long as deep. Scales smooth, 24-25 §^, 2 between lateral line 

 and ventral, 12 round caudal peduncle. 



Yellowish, in spirit, with the sides silvery and bearing three to eight black dots or 

 round spots, the second or third below the dorsal, the last on the caudal peduncle near 

 the caudal fin ; fins whitish, transparent. 



The largest specimen measures 40 millimetres. 



Of the sixteen specimens of this species examined by me, thirteen have 8 branched 

 rays to the dorsal and three have 7. 



The type specimens were obtained at four different places on the White Nile by 

 Mr. Loat, viz., at Lake No, on Feb. 22nd, 1901, at Fashoda, in a kore, on March 16th, 

 1901, at Kaka on March 17th, 1901, and at Gondokoro, on March 6th, 1902. I had 

 taken them, on a superficial examination, for young B. perince, but they are sufficiently 

 distinguished from the latter species by the lower number of scales. At Lake No they 

 were associated with two other dwarf species, B. stigmatopygus and B. pumilus, at 

 Fashoda with B. anema and young B. perince. The species has since been rediscovered 

 at Alexandria by Mr. Schoeller, and in small ponds at Wady Haifa and at Gondokoro 

 by Dr. F. Werner, after whom the species is named. 



In addition to these specimens, I have examined four more, from East Africa, which
