Mr. W. S. Bisat— The Correlation of the Carboniferous Beds of Western 

 Europe. 



Thanks to the great exposures of goniatite-yielding beds in the Pennine area of 

 the North of England, the zonal analysis of the middle portion of the Carboniferous 

 sequence has been carried out to an extent which enables practically all the goniatite- 

 yielding beds of Western Europe to be correlated easily with some portion of the 

 English sequence. 



Such correlations have been obtained in Belgium, Holland, Westphalia, N. of France 

 and Portugal. They also exist farther afield, as in the Sahara and United States. 



In Scotland, Northumberland and Silesia the almost complete absence of goniatites 

 makes correlation more difficult, and to a large extent dependent on the broader 

 floral zones. Also for the main portion of the Lower Carboniferous in all districts we
