as the Bureya Flora or a little younger, however, the flora of 

 Simonova in West Siberia is surely Cretaceous. 



2. The Gyliakian Flora. 



This flora has been studied, and more exactly than others, 

 with the collections from Mgach. The occurrence of plant-remains 

 in this series is very important, as there are no other fossils for 

 the determination of its age. The following table shows a corre- 

 lation of the plant fossils with those of the allied floras.'^
