(4th). — Prom the west of Yarkand to the Pamir Schizothorax, Schizopygopsis and 
Diptychm, all forms found in Turkestan or adjacent regions, and likewise 
Nemacheilm were obtained. 
The foregoing species constitute the fish-collection made in the cold and inhospitable 
regions traversed by the Mission ; and they are of interest for the purpose of ascertaining 
what are the chief characteristics of the fish-fauna, and what relationship it bears to those of 
contiguous Asiatic regions, so far as such have been ascertained. 
In tliis inquiry it will be necessary to take a survey of the fishes of Afghanistan, 
Western Turkestan, and Hindustan, before proceeding further respecting those of Tibet and 
Yarkand or Eastern Turkestan. 
Most of our knowledge of the fishes of Afghanistan is due to the labours of Griffith, 
who remarked “ The characteristic forms of Afghan fish are doubtless the small-scaled 
Barbi and Oreini ; and these far exceed the others in number .... The fish are as distinct 
from the Indian forms as the plants are .... By characteristic I do not mean that these 
forms are limited to Afghanistan, because they occur perhaps to an equal extent in the 
Himalayas, to the streams of which those of Afghanistan approximate more or less in the 
common features of rapids and bouldery beds.” 
Having crossed the high range of mountains separating Afghanistan from the plains of 
Western Turkestan, he found “a great change in the fish to occur, and Salmoniclce 1 seem to 
take the precedence of the Cyprinidce. A species of trout abounds in the Bamean Biver and 
up its small tributaries, derived from the Koh-i-Baba, to an altitude of about 11,000 feet. 
A species of Barbus with small scales is likewise co mm on in the Bamean Biver” 2 (Cal. 
Journ. Nat., Hist., ii. p. 565). 
He observes that Indian species were in the majority in the Cabul river (a tributary of 
the Indus) at Peshawur ; and in accordance with the facility or the reverse of access from the 
plains did he find a predominance of Indian or Afghan forms. 3 
The nature of the fishes of Afghanistan appears to be much as follows : — Absence of 
Acanthopterygian or spiny -rayed families, except the spineless and Avidely distributed Ophio- 
cephalus gachua, Ham. Buch., and the spiny eel, Mastacembclus armalus , Lacep., so common 
in the East from the plains to the summits of mountains. Few Siluroids, but perhaps a 
Callichorus and Amblyceps. Numerous Cyprinoids which appear to belong to the following 
genera — Oreinus , Schizothorax , Bungicc, from near Herat, Barilius, and a Loach 
(? Nemacheilus), perhaps Discognatlms 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. Berea fluviatilis, Linn., obtained exclusively from the Jaxartes and 
some of its tributaries. B. schrenckii, Kess., from Lake Balkash. Lucioperca sandra, Cua ., 
from the Jaxartes. Coitus spinulosus, Kess., very rare in Turkestan, tAVo specimens from 
Khojend. _ 
None of these spiny-rayed fishes were captured at so south a latitude as Kas lg iai. ut 
°f the four species three came from the Jaxartes or its tributaries, the other from Lake Balkash.
