Mollusks. 4333 



H. neraoralis ; although the opinion of Forbes and Hanley is against 

 the existence of specific difference between the two. 



Helix nemoralis. Frequent, especially on the chalk ; varying, as 

 elsewhere, in colour and number of bands. 



„ Pomatia. On the chalk, frequent. 



„ arbustorum. Local, and not common. 



„ lapicida. Rather frequent, more so on the chalk-hills, at the 

 roots of hedges, &c. 



„ pulchella. Well diffused and plentiful in some localities ; 

 the var. costata is also to be found here. 



„ Cantiana. Very common. 



„ fulva. Not uncommon, though rather local; under decaying 

 wood among damp moss. 



„ aculeata. Rather well diffused, but not common. 



„ sericea. Scarce. 



„ hispida. Abundant ; varying in colour and the elevation of 

 the spire, but the thick yellowish white foot of the animal seems 

 to afford a good point of distinction between it and the following. 



„ concinna. Less frequent. I have collected this shell in 

 many localities, from the neighbourhood of London, in Sussex, 

 in Kent, also in Ireland, and have found the characteristics of the 

 animal, its dark colour, the foot narrower and far less fleshy than the 

 last, well preserved in all. 



„ rufescens. Common ; the white variety is also not un- 

 frequent. 



„ virgata. Unequally distributed through the district; com- 

 mon on the chalk. 



„ caperata. Local, and less frequent than the last. 



„ depilata. Rare and local. Marant's-court Hill. 



„ ericetorum. Very abundant on the chalk. 

 Zonites rotundatus. Very common here, as in almost every other 

 district I have searched. I have found the somewhat rare, transparent, 

 and colourless variety. 



„ pygmaeus. Rare ; Knole Park. 



„ alliarius. Very frequent ; occasionally colourless, or of a 

 transparent greenish hue. 



„ cellarius. Frequent, but not large ; sometimes colourless. 



„ nitidulus. Abundant. 



„ „ var. Helmii. Rare. 



„ lucidus. One locality ; the bank of a slow stream, near 

 Bradbourne.
