About a hundred and thirty species, besides numerous varieties, 

 are recorded as British ; and of these, about seventy-five species, 

 as well as many varieties, are found in Cumberland and Westmor- 

 land. Seven species only are peculiar to Westmorland, not yet 

 having been taken in Cumberland. 



I have no doubt that further research will cause many more 

 species and varieties to be added to these; but I thought it 

 advisable to draw up a few notes upon those I have already 

 found. 



The chief localities for fresh-water shells are the Lakes, the 

 Eden and its tributaries, and numerous ponds and ditches. Land 

 shells are to be found all over the ground, and some bury them- 

 selves several inches below the surface. The pretty woods along 

 the margin of our lakes and rivers may be especially mentioned as 

 favourable localities for them; while others are to be found 

 adhering to walls and to the bare surface of rocks, or in natural 

 exposures on hill-sides. 



The specimens of Helix arbustorum. collected on the limestone 

 at Bothel, are stronger than those from the Red Rocks in the 

 immediate neighbourhood of Carlisle ; but there is no apparent 

 difference in the solidity of the other shells on the limestone ; 

 indeed, of the two varieties of H. mfescens mentioned below, only 

 the thinner one exists there. 



The foreign species, Bulimus goodalli, was found in the cucumber 

 beds in the Botcherby Gardens ; and I am indebted to Mr. Duck- 

 worth for my acquaintance with this, for he kindly gave me some 

 specimens. Mr. Turton says that B. goodalli inhabits Guadaloupe, 

 and has been naturalised in Bourbon and England. It was first 

 introduced into the Fauna, and indeed first described in 1822, by 

 Mr. Miller, who found it in some pine-beds at Bristol. It is also 

 common in the same situations in the neighbourhood of London 

 especially in Kensington Palace garden ; and has been found near 

 Manchester by Mr. Williamson. It was first observed by the late 

 Mr. Drummond, the botanist, in 1816.
