BABBITS. 251 



Silvery, brownish on the back ; an indistinct darker lateral band ; fins whitish, 

 transparent. 



The largest specimen measures 65 millimetres. 



About thirty specimens were collected at Bahardar, on Lake Tsana,byMr. E. Degen, 

 on June 4th, 1902. 



This small Barbus is easily distinguished from B. perince by its longer caudal 

 peduncle, and, as a rule, by the smaller number of scales in a transverse series ; from 

 B. trispilopleura by the shorter barbels and the shorter caudal peduncle. It bears a 

 close resemblance to B. inermis, Peters, from the Revugo River, at Tette, Mozambique, 

 which differs, however, in the dorsal fin originating considerably in advance of the 

 ventrals. 



29. BARBUS NEGLECTUS. 



(Plate XLVII. fig. 5.) 



Boulenger, Ann. & Mag. N. H. (7) xii. 1903, p. 532. 



Depth of body three to three and two-thirds times in the total length, length of 

 head four to four and one-third times. Snout rounded, slightly projecting beyond the 

 mouth, shorter than the eye, the diameter of which is twice and a half to three times 

 in the length of the head and equals the interorbital width ; mouth small, terminal or 

 subinferior, its width about one-fourth the length of the head ; lips feebly developed, 

 not extending across the chin ; two barbels on each side, the anterior about half the 

 diameter of the eye, the posterior as long as the eye or a little shorter ; the distance 

 between the barbels less than half the diameter of the eye. Dorsal fin with III 8 rays, 

 last simple ray not ossified and as long as or a little longer than the head, the border 

 of the fin emarginate ; origin of the fin nearer the end of the snout than the root of 

 the caudal fin. Anal fin with III 5 rays, longest three-fifths to two-thirds the length 

 of the head. Pectoral fin acutely pointed, two-thirds to three-fourths the length of the 

 head, not reaching the ventral ; latter below or a little behind the origin of the dorsal. 

 Caudal fin deeply forked. Caudal peduncle once to once and one-third as long as 

 deep. Scales smooth, 26-30 ^r, 2 or 1\ betwen lateral line and ventral fin, 

 12 round caudal peduncle. 



The fish in spirit is yellowish with a broad silvery lateral band, the fins white and 

 transparent ; in some of the smaller specimens traces of the markings characteristic of 

 B. stigmatopygus are more or less distinct, especially a dark dot at the base of the 

 caudal fin and another at the base of the anal. 



Total length 54 millimetres.
