BRITISH LOCALITIES OF FOSSIL SHELLS. 443 
geological map,* the nature of the deposit in which the 
locality of the specimens is situated, may be ascertained ; 
and the remarks previously advanced on the prevailing 
shells of each formation, will afford a general idea of the 
genera to which they belong; and, by referring to the 
figures quoted, the specific names may be determined. 
I subjoin a list of some localities of fossil shells, to direct 
research in places which are likely to be productive.

* A Geological Map of England and Wales, coloured by Mr. Wood- 
ward, under the direction of Sir R. I. Murchison, has been published 
by the Society for the Diffusion of Useful Knowledge, at the low price 
of 5s. Although on a very small scale, and therefore not to be com- 
pared for utility and convenience with that by Pror, PHILLIPS, much 
less with GREENOUGH’s large map, or with Kyipr’s, it will be found 
serviceable.
