Barbus rothschildi sp. n. (pi. XVllI., tig. B.). 



This species represents in the Onm Rbiah the Barbus fritschii of the Oueil Ksili. 

 As in that species the moutli is transverse, crescent-sliaped, with a nearly straight 

 anterior margin of the lower jaw, but without the horny covering of a Capoeta ; the 

 lateral fold of the lower jaw also is very short. 



D. 12. A. 8. L. lat. 32. L. transv. 0/5. 



Osseous dorsal ray rather strong, as long as the head without snout, not 

 serrated. Two and a half series of scales between the lateral line and the root of 

 the ventral. The height of the body is contained 4 times in the total length 

 (without caudal), the length of the head 4f times. Barbels four, rather short, the 

 jwsterior not longer than the eye, which is shorter than the snout and two-uinths of 

 the length of the head. Origin of the dorsal tin opposite to the root of the ventral, 

 and midway between end of the snout and base of the caudal. Pectoral not reaching 

 ventral ; anterior anal rays very long, extending beyond the base of the caudal. 

 Sides of the body with a faint median blackish longitudinal band 



Two specimens, 6A inches long. 



Barbus nasus Gthr. (pi. XIX.).

The specimen obtained by Mr. Hartert is considerably larger and of more 

 advanced age than the tyi)e ; it shows a greater prolongation of the snout, and a 

 much broader and stronger dorsal spine, so that it ai)pears necessary to amend my 

 former diagnosis. 



D. 11. A. 8. L. lat. oO. L. transv. O/lo. 



Osseous dorsal ray exceedingly strong, as wide at the base as tlie orbit, strongly 

 denticulated. There are five longitudinal series of scales between the lateral line 

 and the ventral fin. Length of the head rather more than the height of the body, 

 one-fourth of the total length (without caudal). Snout very long, narrow and 

 pointed, longer than the postorbital portion of the head. Lijis very thick and fleshy, 

 the fold of the lower not continuous with that of the other side. Lower jaw com- 

 pressed and narrow. Mouth inferior, semi-elliptical ; barbels long and fleshy, the 

 posterior thrice the diameter of the orbit, which is one-sixth or one-seventh of the 

 length of the head (in specimens '■) in. long). The root of the ventral is slightly 

 in advance of the origin of the dorsal, which is midway between the end of the snout 

 and the root of the caudal. Anal tin not very narrow, not extending to the caudal. 

 Caudal deeply forked. Pectoral reaching the ventral, ventral reaching the anal. 

 Coloration uniform. 



One specimen, U in. long.
