 i?^^^ iJ^^j/ 24///, 1888, ^j Mr. F. G. Fenn. 



I have thought it advisable in preparing this paper on our 

 British Land and Freshwater Shells to abandon my first idea 

 of treating the whole group, and to give, instead, a short 

 account of those species that are found within the South 

 Eastern Counties. The Society's district is too well-known 

 to require defining, and the map which I have brought is not 

 to show its extent, but merely how it may be divided into 

 several natural divisions, each characterised by the presence 

 or prevalence of distinct shells. 



That the South Eastern Counties are rich in mollusca will 

 be seen from the fact that of the 136 species on our British
