THE CRETACEOUS ROCKS OF BRITAIN. 
Mr. Price appears to have imagined that the “ marl with Belem - 
nites ” occurred at the top of what previous writers had called Grey 
Chalk, and to have identified it with the “ thin yellowish beds ” 
mentioned by Phillips; whereas in reality these bands are more 
than 50 feet below the Belemnite marl, which is at the top of 
Phillips’ white chalk with few fossils (No. 6 of Mr. Whitaker). It 
was therefore a mistake to include this white or whitish chalk 
under the head of “ Grey Chalk.” 
The point will perhaps be made clearer by throwing the different 
classifications into a tabular form, thus : —
