1870.] MR. F. DAY ON THE FISHES OF YARKAND. 801 



nus, Schizot/iorax, Bungia from near Herat, Barilius, and a Loach 

 (? Nemacheilus), perhaps Discognathus and Barbus. 



The fullest account we possess of the fishes of Western Turkestan 

 is that lately given by Kessler, from which I have extracted the 

 following : — 



Acanthopterygii. Percafluviatilis, Linn., obtained exclusively 

 from the Jaxartes and some of its tributaries. P. schrenckii, Kess., 

 from Lake Balkash. Lucioperca sandra, Cuv., from the Jaxartes. 

 Cottus spinulosus, Kess., very rare in Turkestan, two specimens 

 from Khojend. 



None of these spiny-rayed fishes were captured at so south a 

 latitude as Kashgar. Out of the four species three came from the 

 Jaxartes or its tributaries, the other from lake Balkash. 



Siluride. Siluris fflanis, Linn. Generally spread throughout 

 Western Turkestan, having been received from the Jaxartes, Oxus, 

 and Sarekshan or Tarafshan rivers. 



Cyprinid.e. Cyprinus carpio, Linn., from the Jaxartes, Oxus, 

 Sarekshan rivers. Barbns conocephalus, Kess., from Sarekshan.

 B. lacertoides, Kess., from Jaxartes and its tributaries. B. brachy- 

 cepJiuhis, Kess., from Jaxartes and Oxus. Scliizothorax aksalensis, 

 from the river Aksai. S. fedtschenkoi, Kess., <S. ajfinis, Kess., and 

 S. eurystomus, Kess., from the Sarekshan river. S. orientalis, 

 Kess., from a lake on the Alatau mountains, the waters on the 

 Western Turkestan side of which drain to Lake Balkash. Diptychus 

 severzowi, Kess., Aksai and Ottuk rivers to 10,000'. D. dybowskii, 

 Kess., river Aksu. Gobio Jiuvlatdis, Cuv., widely distributed in

 kend, Hhodjaduk, and Lake Iskander, the waters of which appear to
