Catalogue of the Land and Fresh-water Shells inhabiting the Neigh- 

 bourhood of Dublin. By William White Walpole, Esq. 



Quite coinciding in the sentiments expressed by Mr. Taylor, in 

 his Catalogue of the land and fresh-water shells of Aberdeenshire and 

 Kincardineshire (Zool. 3878), as to the utility of such local lists, I beg 

 to forward a list of those land and fresh-water Mollusca which I have 

 found inhabiting the neighbourhood of Dublin. 



It would, I doubt not, have been more perfect, had not the marine 

 Conchology of our interesting island engaged most of my attention. I 

 have heard of other species having been found near Dublin, but have 

 included in my Catalogue none but those I have found myself, living 

 in the various localities specified, which are mostly within eight miles 

 South of our metropolis. 



The nomenclature is according to Gray's edition of Turton's ' Ma- 

 nual of Land and Fresh-water Shells.'
