THE LAND AND FRESHWATER MOLLOSCA OF SURREV, 



with the Localities where the Species and Varieties 



have been found. 



Bv CHARLES PANNELL, Jr. 



(Read before the Societj', De;ember ii, 1901). 



Having personally felt the need of a guide to the distribution of 

 species in my own county, I have compiled this list with a view to 

 assisting other members of the Society and students of conchology, 

 who may have opportunity of collecting in Surrey. 



The county is divided into eleven districts and the extent or area 

 of each district is determined by the border line of the county; its 

 rivers, downs and other physiographical features as fully shown in the 

 key given below. The classification of the Society's list of "The 

 British Land and Freshwater MoUusca " (1S92), has been followed 

 with the addition of two or three varietal names. 



The following abbreviations are used to indicate the authorities for 

 the records given in the paper. To the gentlemen named in the list 

 I beg to offer my thanks for the information they have been good 

 enough to sive me. 



(R.A.B.) Rev. R. Ashington Bul- 

 len, F. L.S. (through the kind- 

 ness of Mr. Swanton). 



(J. E.G.) Mr. J. E. Cooper.
