A good number of impressions of Conifersß from the Gyliakian 

 belongs to tliis very typically Cretaceous species, broadly distribut- 

 ed from the lowest to the upper horizons of the Cretaceous, both 

 in Europe and in America. 



The same species was recognized by Shimotomai-Tanakadate 

 in Onennai in Japanese Sakhalin, in the lower part of the upper 

 division of the Cretaceous. 



Probably some other species of the genus will be found in the 

 other part of our collection, now lying in Petrograd.
