 Orientalis and Podozamites Eeinii are available for deter- 

 mining the age of the strata. The fossil flora is of the type of 

 the Tetori Series and according to Yabe, represents the Malm- 

 Dogger epoch in Korea. Later, Inouye '^ made a find of 

 Onychiopsis elongata ((jieyler) at the Ka-cliln pass on the 

 north of Hyöp-chhißn.
