PISCES* {Fishes).
T h e vertical distribution of Turkistan fishes cannot so well be expressed
as that of Mammals, Birds, Reptiles, and Amphibia. The chief
water systems of the region are those of the Aral, the Balkhash, and
the Upper Tarim. There are other systems of second grade-, of which
the more important are those of the Issyk-Kul, the Chu, Talas, and
Zarafshan. The last three, however, might be added to the Aral
system.
The principal ichthyological districts of the region are also three
(those of i, the Marinka— Schizothorax—and OsmanofE— Oreinus et
Diptychus; 2, the Carp, the Silurus and Barbel, together with the
Marinka; and 3, the Aral Sturgeon); but each of them consists of parts
of the different water systems, and, on the other hand, the Syr-daria,
at different portions of its course, belongs to all three ichthyological
districts.
In the following list each of the ichthyological districts is designated
by a Roman figure, and the distribution of each species in the districts
by an Arabic figure, showing the place of finding, thus :— -

new ones have been described by Kessler. The species marked with an
asterisk are common also to the Caspian and Black Seas.
