368 W. #. Alkins—Brachiopod Beds at Cauldon, Staffs. 
church stands is formed by a block of limestone projecting from the 
main mass, and its structure is an interesting problem. 
The fauna which has been obtained from these beds is given in the 
tables below. An attempt has been made to refer each species to a 
published figure, in the hope that this will increase the value of the 
lists. As is always the case, in studying a large suite of specimens 
from the brachiopod beds many forms cannot be matched against 
illustrations ; to these no reference is made.
