A comparison of our results with those of Krotov and Shibkova (1961) and Krotov (1957a, b) leads to the conclusion that the abundance and system- atic composition of the silicoflagellate flora of the Early Paleocene were roughly uniform on the eastern slope of the Urals from the Ust' - Man'ya River in the north to the Kamyshlov area in the south. Nevertheless, our materials show a greater variety of forms compared to those of Krotov, probably because of the more detailed determination. In the study of the Early Paleocene silicoflagellates of the Volga area we used materials from the Penza and Ul'yanovsk regions (Table 48). 177.
