Discussion. 



Mr. Steahan regretted that the useful work in this paper had been 

 obscured by an unnecessary introduction of the Continental nomen- 

 clature of the strata. Not only was such a nomenclature out of 

 place in dealing with so strictly local a subject, but the names them- 

 selves had no definite meaning in this country, for the Author's recent 

 delimitation of the Cenomanian was not accepted by Continental 

 .geologists. The introduction of such names had never failed to 

 xjause confusion in British local stratigraphy, and should be reserved 

 for papers dealing with international questions. 



Mr. E. T. Newton and the President also spoke.
