XIV. — Descrijitions of Five neio Cyprinid Fishes from Lhasa, 

 Tibet, collected bi/ Captain IL J. Walton^ l.M.S. By 

 C. Tate Regan, B.A. 



During the recent expedition to Tibet, Captain H.J. Walton 

 made a small collection of fishes, which he has forwarded to 

 the British Museum. Of seven species represented, six appear 

 to be new to science, the exception being Nemachilus 

 StoUckzce, Day. This result is not surprising, for I believe 

 that fishes have not before been described from this part of 

 the Brahmaputra system. Five Cyprinid fishes are described 

 below, whilst a ntw Silurid, Parexostoma maculatum^ is 

 described on p. 183. 



1. Schizopygopsis Younghusbandi. 



Pharyngeal teeth 4 : 3 — 3 : 4, cylindrical, obtusely pointed, 

 those of the outer series slightly curved inwards. Depth of 

 body 4^-5^ in the length, length of head 4-4^. Breadth of 

 head l^-lf in its length, diameter of eye 4-6, length of 

 snout 3i-4, interorbital width 2f-3i. Snout obtuse; ante- 

 rior edge of upper jaw slightly below the level of the lower 

 margin of the eye ; maxillary extending to below anterior 

 edge of eye; lower jaw shorter than the upper, with a nearly 

 straight transverse anterior edge. Dorsal III 8-9, its origin 

 a little nearer to tip of snout than to base of caudal ; third 

 simple ray slender, articulated, not serrated. Anal III 5-7. 

 Pectoral extending i-g of the distance from its base to the 

 base of ventral. Origin of ventral below or a little behind 

 the middle of dorsal. Caudal forked. Caudal peduncle 2^-2^
