LIST OF LAND AND FRESHWATER 



MOLLUSCA OCCURRING IN THE MAIDSTONE 



DISTRICT. 



By H. ELGAR and H. LAMB. 



(Read before the Conchological Society, March 4th, 1S91). 



\Tlie spcci/iieiLS illustrating this paper have been kindly presented to the 

 Conchological Society by the Authors']. 



The following list is not put forward as an exhaustive one, 

 as will be seen by the absence of some species, which in all proba- 

 bility occur in the district, viz., of the genera Fisidiuni, Aiicyliis, 

 Vertigo, etc. 



The physical aspect of the district is varied ; we have the 

 Chalk Hills to the north, the Ragstone range in the south, 

 divided by the Folkestone Sand, which runs east and west at the 

 foot of the Chalk; it is watered by the Medway, with its 

 tributaries and marshes, also several large ponds and streams. 



This part of Kent has been but little worked by conchologists, 

 and will no doubt eventually yield a good many not in this list.
