THE CRETACEOUS ROCKS OF BRITAIN. 
In reality the bed consists of soft yellowish-grey or buff-coloured 
marl, and it separates the smooth white-jointed chalk of Bed 8 from 
the nodular yellowish-white gritty chalk which represents the 
Melbourn Bock. It is the Belemnite Marl of our nomenclature 
(p. 20). 
Actinocamax plenus is not uncommon in this marl, but 
other fossils are rare, the only species recorded by Mr. Price being 
Ptychodus decurrens, Pty. polygyrus and Plicatula inflata . 
The following is a list of the fossils which have been obtained 
from the several beds or subdivisions of the Lower Chalk between 
Folkestone and Dover. The list is based on that given by Mr. Price, 
the fossils entered on his authority being indicated by the letter 
P ; those obtained by the Survey collector are marked S ; a few 
(marked B) are quoted from Professor Barrois’ paper on the Bou- 
lonnais,* and are credited to our Bed G, though one or two may 
have come from No. 5. These species were identified by M. Cotteau. 
Fossils from the Lower Chalk near Folkestone.
