BRITISH SHELLS. 



Convinced of the importance for the identification of the Na- 

 tive Species, of possessing carefully named rudimentary Collec- 

 tions of BRITISH SHELLS, R. Damon, of Weymouth, has 

 been induced to devote his attention more particularly to that 

 branch of Conchology, and favored by the prolific nature of the 

 Dorsetshire and neighboring coasts, is enabled to offer arranged 

 collections at the following very moderate prices: 



100 Species, (containing 1 to 3 of each Species,) £2 12 6 



200 do. do. 6 6 



300 do. do. 12 12 

 400 do. do. 



R. DAMON has unusual opportunities for procuring many of 

 the rare British Shells, and has always on hand an extensive 

 collection of British Fossils.
