XLIII. — Descriptions of Tioo new African Species of Burbus. 

 Bj G. A. Boulenger, F.R.S. 



The paradoxical section of Barbels without barbels [Systomus^ 

 McClelland, Bleeker), long believed to be restricted to South- 

 eastern Asia, has, within the present century, received several 

 additions from Africa. Two further species are here described, 

 bringing the number of African species up to eight, Vvfliich 

 may be distinguished by means of the following key : — 



A. Lateral Hue complete. 



Sc. 29-32 3 ; depth of body 3| to 3J times in 



total length ; caudal peduncle .-wice as long [1906 (L. Viotoria). 



as deep B. Magdalemc, lilgr., 



Sc. 28 ?| ; depth of body 3 times in total length ; 



caudal peduncle once and \ as long as [1902 (Con^^o). 



deep B. Brazzce, Pellegr., 



Sc. 25 ||; depth of body 2^ times in total [(S. Cameroon). 



length ; caudal peduncle as long as deep. . B. aspilus, sp. n. 

 Sc. 22-25 ?Hi; depth of body 2§ to 3^ times 



in total length ; caudal peduncle not or but [(Nile). 



slightly longer than deep B. anetna, Blgr., 1903 



Sc. 23 g|; depth of body 3| times in total 



length ; caudal peduncle once and \ as long [(CoDgo ?), 



as deep B, trispilomunus, yp. u. 



B. Lateral line absent or reduced to a few tubules ; depth of body 

 equal or nearly equal to length of head, 3 to 3| times in total 

 length. 



Sc. 22-25 ^tnj! ; origin of dorsal midway be- [1903 (Nile).
