344 THE DISPERSAL OF SHELLS. 



is supposed to have been introduced near Guildford 

 by an Earl of Arundel. The correspondent to Nature^ 

 before quoted, who lived from 1849 to 1852 within 

 two miles of Woodford, Northamptonshire, where this 

 species occurs in a small wood known as Woodford 

 Shrubbery, stated that it was commonly said in that 

 neighbourhood that the snails were originally brought 

 from abroad by General Arbuthnot (?) who had formed 

 the Shrubbery some thirty years before. It seems 

 likely that there is some foundation for such statements 

 as these, or some of them, and it can hardly be doubted 

 but that the animal, although possibly or probably truly 

 indigenous, has been imported from abroad from time 

 to time.^
