MR. G. A. BOULENGER ON FISHES 



[Apr. 9, 



LimpojDO River, except for the presence of two pairs of barbels. 

 I cannot help thinking that the absence of anterior barbels in 

 the type specimen is clue to an anomaly, or that their presence 

 has been overlooked. 



5. Barbus eut^nia Blgr. 



Several specimens from Klein Olifant River. This species, 

 originally described from Angola {B. kessleri Gthr. nee Stdr.), has 

 recently been rediscovered in IST.W. Rhodesia by Mr. ISTeave. 



6. Barbus polylepis, sp. n. (Text-fig. 90.) 



Depth of body 41 times in total length, length of head 3§ times. 

 Snout rounded-subacuminate, 3 times in length of head, feebly 

 projecting beyond mouth ; diameter of eye A\ times in length of 

 head, interorbital Avidth 3^ times; mouth small, inferior, its 

 width 4 times in length of head; lips well developed, lower 

 continuous across chin; two barbels on each side, subequal in 

 length, f diameter of eye. Dorsal III 8, last simple ray strong, 

 bony, not serrated, its rigid part | length of head ; free edge of 



Text-fig. 90.

the fin strongly emai'ginate ; its distance from posteiior border 

 of eye equals its distance from caudal. Anal III 5, longest ray 

 ^ length of head, not reaching root of caudal. Pectoral | length 

 of head, not reaching ventral ; latter below anterior rays of 

 dorsal. Caudal deeply forked, with pointed lobes. Caudal 



peduncle twice as long as deep. Scales 43 c^, 5 between lateral 

 line and ventral, 18 round caudal peduncle. Olive-grey above, 

 white beneath. 



Total length 120 millim. 



A single specimen from Klein Olifant River. 



In the Groot Olifant River, Capt. Bruce obtained a large Barhus, 

 weighing 3| lbs., and too large for him to preserve, which, from 

 the notes he has taken, probably represented the adult of the fish 

 here described. Capt. Bruce counted 42 scales in the lateral line, 

 8j in a transverse series above the lateral line, and 6 between 

 the latter and the ventral fin. This large specimen further 

 diflfered in the much longer rays of the anal fin.
