XI. — Cornish Marine Shells. From A Coreesfondent. 



THE following List of known Cornish Marine Shells comprises 

 303 species, besides many varieties. Mr. Jeffreys' interesting 

 and valuable work on British Conchology being completed only so 

 far as the Genera Lacuna and Littorina of Fam : Littorinidce, the 

 nomenclature of Forbes and Hanley has been generally adopted for 

 the remaining species, some of which were undiscovered in 1853. 



The genera Spirialis Adeorlis and lanthina, although inserted 

 before Littorina, have not yet been described by Mr. Jeffreys. 



The letters "R" and "RE" denote the supposed rarity of the 

 particular species as Cornish. Those not so distinguished are more 

 frequent on our coasts. 



Where no locality is given, the species has been found in several 

 places.
