ZOOLOGY 



MOLLUSCS 



Warwickshire is not a very suitable county for molluscan life since 

 so much of its subsoil consists of sandstone. Nevertheless 93 species out 

 of a possible 139 for the whole British Islands have been found ; while 

 one other form, Physa beterostropba, introduced from the United States, 

 occurs near Birmingham. 



The freshwater forms as might be expected show the higher per- 

 centage of occurrences. 



The whole assemblage is typically British, extreme northern and 

 western forms being absent, nor does Pomatias e/egans occur. 



A few more species may yet be discovered, notably among the 

 Vertigos. 



The literature on the subject is small and scattered, the three 

 principal papers being : one on the neighbourhood of Birmingham by 

 G. SherrifF Tye, 1 that on the Rugby district by E. E. Austen 2 and a list 

 for Sutton Coldfield by A. Wood. 3
