ZOOLOGY 



MOLLUSCS 



Ninety-eight species of non-marine moUusca have been recorded 

 from Worcestershire out of a total of 139 known to inhabit the British 

 Isles, and this, when the scanty number of published lists is taken into 

 account, is a very good number. 



In this estimate no note is taken of four species {Helicella barbara. 

 Pupa anglica, Clausilia biplicata, Unio margaritifer) which find their place 

 in one list, but are apparently due to erroneous determinations. 



The occurrence of Pupa secale in the Malvern district, if correct, is 

 of interest, since the species is not as a rule met with so far inland. 



Testacella maugei is presumably an importation with garden or hot- 

 house plants : for the rest the assemblage is a typically British one. 



Several of the localities mentioned in the list are probably no longer 

 habitats for mollusca, since owing to the rapid increase of buildings 

 some of them have become parts of towns : e.g. Acock's Green, Selly 

 Oak and Hall Green.
