3l6 JEFFERY: the MOLLUSCA of western SUSSEX. 



and near Lewes (Zoologist, 1878). 



Helix pygmsea. Have not found this snail myself, but my friend 

 Mr. H. Haines has given me specimens which he 

 collected last season at Weodend near here. 



H. pulchella. Equally common from the Downs to lowland 

 meadows at the roots of herbage and under stones. I . 

 find great numbers on the lawn in my garden. 



H. lapicida. Common in beech woods on the chalk; after a 



shower the stems of these trees are often covered with 



them; also about loose stone walls and ivy-covered 



palings. On the flat country, south of the Downs, it 



is rare if not altogether absent. It occurs in Hayling 



Island. 

 H. obvoluta. Distribution very restricted: occurring generally 



only on the northern ranges of the South Downs. Has 

 been taken plentifully at Up Park in the extreme north- 

 west of the county, adjoining Hampshire, and is also 

 reported from Duneton, Graffham and Storington, 

 further east. I have occasionally found dead shells for 

 the last ten years, on a bank at Woodend, at the base 

 of the Downs, but no living specimens, even after many 

 careful searches during that period, so I conclude it has 

 died out — it may have been introduced there. 



Bulimus obscurus. The only representative of this genus 

 found in Sussex, though B. montanus is common at 

 Selbourne in Hants, only a few miles over the boundary. 

 Beech woods on the chalk : common. 



Pupa umbilicata. Common and generally distributed. 



P. marginata. Not so numerous as the last, but occurring 

 from the Downs to the sea. 



Vertigo pygmaea. Under stones, &c., from the Downs to the 

 lowland meadows.
