This report deals with Foraminifera, algae and some microfossils of uncertain taxonomic position collected from the 2 most complete Silurian sections found at the Western slope of the Central Ural; it is the first work concerned with composition and stratigraphic distribution of Silurian Foraminifera in the Ural. Only the most typical spp. of the Wenlockian and Ludlovian belts are described. Altogether 26 spp. of microfauna and flora are listed, of which 3 are of uncertain origin: 2 new genera, ARAKAVAELLA (type sp. A. arakaica Parathuramminidae, Astrorhizida, Foraminifera) and SERGINELLA (type sp. S. scabruma); another 3 new spp. belonging to the genera Paramurammina, Cribrosphaeroides and Archaelagena, all Foraminifera, are described. One known sp. of Coactilum and 2 new spp. incerta sedis, all Porostromata, Cyanophyceae, are also described. Their distribution in the sediments is graphed and discussed, according to the importance of their occurrence in the various sediments. The stratigraphic ally most important fossils belong to the families Hyperamminidae (Earlandia sibirica typical for Ludlovian), Parathuramminidae (Cribrosphaeroides enormls typical for Wenlockian, P. polygona and A. rotunda for Ludlovian). Among the incertae sedis algae were spherical fossils preliminarily classified as Calcisphaera sublucida, apparently an earlier form of Calcisphaera known from the Lower and Middle Devonian. Leading stratigraphic algae were Coactilum silurica, with ample horizontal and narrow vertical distribution, and Syniella lucida, both Ludlovian. Ludlovian microfauna were more numerous and multiform than Wenlockian.
