232 On some new Species of Fishes from Moi'occo. 



others, and not serrated. There are two and a half longitudinal 

 series of scales between the lateral line and the root of the 

 ventral. The height of the body is contained thrice and one 

 fourth in the total length (without caudal), the length of the 

 head four times. Snout short and obtuse, with the mouth 

 inferior, broad, short, and crescent-shaped ; the lower jaw with 

 rather a sharp margin. Barbels four, short. The diameter 

 of the eye equals the length of the snout, and is two sevenths 

 of that of the head. Origin of the dorsal hn nearly midway 

 between the end of the snout and the root of the caudal, opposite 

 to the base of the ventral. Anterior anal rays very long, ex- 

 tending beyond the root of the caudal. A more or less distinct 

 narrow greyish longitudinal band runs from the back part of 

 the eye above the lateral line to the middle of the caudal fin, 

 and separates the darker coloration of the back from the silvery 

 of the belly. 



This is a small species, apparently abundant in the streams 

 near Morocco (Oued Ksib). The largest specimen is only 

 4^ inches long. 



Barhus nasus. PI. XIV. fig. B. 

 D. 11. A. 8. L. lat. 45. L. transv. 9/10. 



Osseous dorsal ray strong, strongly serrated. There are five 

 longitudinal series of scales betv.'een the lateral line and the 

 ventral fin. The length of the head is rather more tlian the 

 height of the body, and one fourth of the total (without caudal). 

 Snout very long, much pointed, as long as the postorbital 

 portion of the head ; lips very thick, the lower with the fold 

 interrupted in the middle ; mouth inferior ; barbels very fleshy 

 and much longer than tlie eye, which is small. The base of 

 the ventral fin is conspicuously in advance of the origin of the 

 dorsal fin, which is nearly equidistant between the end of the 

 snout and the root of the caudal. Anal fin not very narrow, 

 none of the rays extending to the caudal. Caudal deeply 

 forked. Coloration uniform. 



The larger of the two specimens sent is 5\ inches long. 

 They bear the number 39; and on refen-ing to the corresponding 

 number in the list of localities I find that the specimens are 

 said to have been obtained, with other marine fish, on the sea- 

 shore near Mogador ; I cannot help thinking that some mistake 

 has taken place, and that these specimens were obtained from 

 fresh water, like the other species of this genus.
