A CONTRIBUTION TOWARDS 



A LIST OF THE LAND AND FRESHWATER MOLLUSCA 



OF BRECONSHIRE AND RADNORSHIRE. 



By J. WILLIAMS VAUGHAN. 



(Read before the Society, December 9, 1903). 



As I have never heard of any attempt at an enumeration of the 

 molluscan fauna of these hiland counties, I thought that the following 

 list of the species I have myself found might be of interest to 

 members, especially as I find, on submitting them to the Recorder, 

 that twenty-six are new records for Brecon and four for Radnor. The 

 new records are indicated by an asterisk.
