DISTRIBUTION OF BRITISH LAND & FRESHWATER MOLLUSCS. 



The Editor would be pleased to correspond with Malacologists in the various 

 counties of the British Isles with a view to obtaining and publishing a complete 

 record of the distribution of the Molluscan fauna as the list compiled by th 

 Conchological Society only deals with specimens coming under the notice of its 

 referees and is therefore incomplete. 



The Editor would still be glad of living specimens of Testacella from any localities. 



All communications must be addressed to Wilfred Mark Webb, " Ellerie," 

 Brentwood, Essex.
