In the summer of 1912, the author of the note visited the middle and lower part of the Kara-Turgai river basin, which occupies the central part of the Turgai district. On the way, he examined a fairly large number of outcrops, and in some of them a rather rich fauna was encountered. The results of these observations are presented in this note. The central part of the Turgai district of the Turgai region has so far been visited by very few researchers and travelers.
