The foregoing fishes of Western Turkestan 1 mainly consist of—

Berea, Lucioperca, Gottus, Gobio, Abramis, Acanthobrama, Belecus, Alburnus, 
Aspius, Squalius, Leuciscus , Acipenser, and Scaphirhynchus. 
(2nd ).—Those common to Afghanistan and Yarkand, as Schizothorax, Barbus, Loaches

(3rd ).—Those found also in Yarkand, as Schizothorax and Diptychus. 
(4th). — Silurus, (which will he alluded to). 
Lastly, Salmo, on the slopes of the mountains where the rivers descend to the Oxus. 
The existence of one of the Salmonidce, termed Salmo orientalis by M’Clelland, was 
well known to Dr. Stoliczka; and a special object of his search (as he informed me previous 
to starting) would he to try and ascertain its distribution. Griffith found this fish “ in the 
Bamean Liver, a stream that falls from the northern declivities of the Hindoo Koosh into 
the Oxus.” 
1 I have to thank Mr. F. Carl Craemers for kindly translating some Russian localities, which I should not otherwise have been 
able to give.
