faunistically different horizons may be likewise distinguished : — 

 the lower (C^) (horizon of Spirifer mosquensis) and the upper (C3) 

 (horizon of Prochicius coro). The latter is a Fmulina-Wme^ionQ 

 and is covered by that of Schwager ina. 



In the Oka-Kljasnia and Oka-Wolga basins, the horizon of 

 Choneies uralica is overlaid by Schwagerina Dolomite. 



As may be seen from the above, the Schvmgerlna-Wme^iow^ 

 of the Ural mountains, must be placed on a somewhat higher 

 level than the Gshelian stage. The Artinskian marls and sand- 

 stones (Cpg) conformably overlie the Schwagerina horizon. 



The species of Fusulina which is a genus very widely 

 distributed in the Russian Carboniferous and Permian, was fully 

 worked out by Möller a quarter of a century ago. According 

 to the works of Möllee, and those of Krotow, Stuck enberg, 

 SiBiEiZEAV, and Tscheenyschew^' which subsequently appeared, I
