Remains in the Oolite Series of England and France. 261 



M. Boblaye furnishes us with the following lists of organic 

 remains in the Stenay blue marls and the Oxford clay; these 

 he has kept distinct, because he is not certain whether the 

 former should be united to the cornbrash or to the Oxford 

 clay.

 structed, of organic remains which occur in more than one of 

 the localities mentioned: the Stenay marls being considered as 

 part of the Oxford clay ; they may indeed represent the Kel- 

 loway rock.
