LIST OF SHELLS FOUND IN THE NEIGHBOUR- 

 HOOD OF YEOVIL, N. SOMERSETSHIRE. 

 By J. PONSONBY. 



The Land and Freshwater Shells of Somersetshire have 

 been the subject of many able and exhaustive articles. The 

 following list is purely a local one, all the specimens having 

 been collected by the writer within the limits of a walk from 

 Yeovil. The neighbourhood is tolerably rich in the land shells, 

 considering the very small extent of country investigated. As 

 to the freshwater species, however, we are rather badly off. 

 The Yeo, the only river, is a rapid, and in the summer, a 

 shallow stream ; there are apparently no lakes or large ponds 

 where the Paludince, Limncea stagnalis, &c., are likely to be 

 found, though from other parts of the county these species have 

 been recorded. The conditions also are unfavourable for Fupa 

 and Vertigo, several other species of both these genera being 

 known from other parts of the county. Unfortunately the 

 bivalves have been much neglected, as no doubt the ponds of 

 the neighbourhood would on investigation yield several 

 additional species. It is hoped that another year will remedy 

 this omission.
