 diameters in the length of the head and situated in its middle. Interorbital space nearly flat: snout pointed.

 the centre, lower with a central lobe and a lateral one on either side. Lips internally covered with a thin, 

 deciduous, cartilaginous layer. Barbels — four, the rostral- about as long as the orbit, the maxillary pair 

 rather shorter. TeeiA— pharyngeal; crooked, pointed, 5, 3, 2/2, 3, 5. Fins — dorsal commences slightly in 



longer. Barbels shorter than the eye. Origin of dorsal fin nearer caudal than snout : spine as long as head excluding snout. Anal

 the length of head. Upper jaw the longer. Barbels as long as eye. Origin of dorsal fin nearer caudal than snout : its spine 2/3 to 4/5 

 as long as head, coarsely serrated. Anal laid flat reaches the caudal. Tiled row of scales half as deep as orbit. Afghanistan and 

 Turkestan. 



11. Schizothorax nams, Heckel, 1. c. p. 33, t. vi ; Gunther, 1. c. p. 166. Eye 6 in length of head. Upper jaw the longer.

 feebly serrated. Anal when laid flat reaches caudal. Tiled row of scales minute. Panja from a tributary of the Oxus. 



13. Schizothorax longipirmis, Heckel, 1. t. p. 27, t. iv ; Gunther, 1. c. p. 166. Eye 5 in length of head. Upper jaw slightly 

 the longer. Barbels nearly 1/2 as long as eye. Dorsal fin commences nearer caudal than snout : ita spine moderately strong and 

 serrated. Anal laid flat reaches caudal. Tiled row of scales not 1/2 as broad as orbit. Cashmere. 



14. Schizothorax chrysochlorus, Day, 1. c. p. 784, and Plate cxxiii, fig. 2 ; Bacoma chryaochlora, McClelland, 1. c. p. 677, t. XT,

 Barbels at least as long as the eye. Dorsal fin arises midway between end of snout and base of caudal : its spine strong, serrated, and 

 as long as the head. Anal when laid flat reaches 1/2 way to the caudal. Tiled row of scales 1/2 as broad as the eye. Afghanistaa 

 and Turkestan. 



15. ScMzotJwrax noUUs, Bacoma noiiUs, McClelland, 1. c. p. 577, t. xv, f. 4. Eye about 6 in the length of head. Upper jaw

 points. Upper jaw projecting. Origin of dorsal fin nearer caudal than snout : spine serrated posteriorly. Anal laid flat reaches the 

 caudal fin. Afghanistan. 



17. Schizothorax gobioides, Bacoma golioides, McClelland, 1. c. p. 576, t. xv, f. 3. Eye 4§ in the length of the head. Barbels 

 longer than the eye. Upper jaw much the longer. Origin of dorsal fin midway between snout and base of the caudal : its spine as long 

 aa the head excluding the' snout, and serrated posteriorly. Anal fin laid flat does not reach the caudal. Tiled row of scales about as 

 broad as orbit. Afghanistan. 



18. Schizothorax hrevis, Bacoma Irevis, McClelland, 1. c. p. 578. " Head short and compressed. Lips covered with a thick 

 fleshy membrane, which forms a loose appendage to the lower jaw. Depth of body neai-ly equal to 1/3 of its length. Fins small, rays 

 slender, the dorsal spine slender and soft." Afghanistan. 



Amongst the foregoing 1 8 species it is most probable that several will turn out to be synonyms : some of McClelland's examples 

 may belong to the Genus Oreinus.
