Numerous apechnens from BaharJar, Lake Taaua, June 4, 

 1902. 



The nearest ally of this small Barbel appears to be B. in- 

 ermis, Peters, the dorsal of which originates ia front of the 

 vertical of the base of the ventrals. 



Barhus trispilopleura. 



Depth of body equal to length of head, 3^ times in total 

 length. Snout rounded, 4 times in length of head ; diameter 

 of eye 3 times in length of head, interorbital width 2^ times ; 

 mouth terminal, its width 4^ times in length of head ; lips 

 feebly developed ; barbels two on each side, the anterior |, 

 the posterior a little longer than diameter of eye. Dorsal 

 III 7-8, last simple ray not enlarged, flexible, as long as 

 head ; free edge of the tin not emarginate ; its distance from 

 the occiput about ^ its distance from the caudal. Anal III 5,

 not reaching ventral ; latter below anterior rays of dorsal. 

 Caudal peduncle 1§ as long as deep. Scales 27-28 ^, 2 be- 

 tween lateral line and ventral, 12 round caudal peduncle. 

 Brownish above, silvery on the sides and below ; three round

Three specimens from Bahardar, Lake Tsana, June 4,

Kesembles B. trimaculatus, Peters, in general appearance, 

 but the scales are fewer, the last unbranched dorsal ray is 

 weaker, and the barbels are shorter. 



Nemachilus ahysslnicas. 



Depth of body 7 times in total length, length of head 5 

 times. Head feebly compressed belund, twice as long as 

 broad. Snout a little shorter than postorbital part of head, a 

 little depressed ; eye 6^ times in length of head, i] interorbital 

 width ; longest barbels twice diameter of eye. Dorsal 10, 

 a little nearer caudal than occiput, originating immediately 

 behind vertical of root of ventral, middle rays longest, nearly 

 £- length of head. Anal 9. Caudal slightly emarginate. 

 Caudal peduncle 1^ as long as deep. Yellowisli brown, with
