ANOTHER NEW BABBUS FROM MOROCCO. 



By G. a. BOULENGER, F.R.S. 



MR. RIGGENBACH, who has added miicli to onr knowledge of the fresh- 

 water fishes of Moroeeo, has recently made a small collection in the 

 Wed Ksib, containing, along with AnguiUa i-ulgaris and Jiarbiis cfiUfnais, 

 examples of a new species wliich I propose to name 



Barbus ksibi. 



Depth of body 31 to 4^ times in total length ; length of head 3J to 3J times. 

 Snont obtusely pointed, li to 2^ times as long as eye; diameter of eye, 4 to 

 times in length of head; interorbital width 2;\ to 2i times ; mouth inferior, its 

 width \ to f length of head ; lips well developed, interrupted on the chin ; 

 barbels, two on each side, equal in length, H times to twice diameter of eye, longer 

 than the distance between them. Dorsal III 7 — 8, last simple ray moderately 

 strong, serrated at the base, A to | length of head ; free edge of the fin convex ; its 



Barliiis Itsibi, J- natural size, with upper \iew of head and detached third dorsal lay. 



distance from the occiput equal to or slightly less than its distance from the 

 caudal fin. And III 5, longest ray | to f length of head, reaching root of caudal 

 or a little beyond. Pectoral abont '4 length of head, not reaching ventral ; latter 

 a little shorter, below anterior rays of dorsal. Candal peduncle about IJ as 



Ion"- as deep. Scales 41—40 If^^f, 4 between lateral line and ventral, 18 or 20 



i .7 0.7 



ronnd candal peduncle. Brownish above, white beneath ; fins white. Several 

 specimens, measuring from 100 to 220 mm. 



This species is closely allied to ]i. sctiiimensis, but easily distinguished by 

 the convex shape of the dorsal fin and its weaker spine.
