THE LAND MOLLUSCA OF PUFFIN ISLAND. 3 



half way round and two bands on the remainder. Many 

 of the hving shells are w-eathered to a greater or less 

 extent, which may be accomited for by the very exposed 

 situation of the island. 



Helix liispida, L. 



A few specimens found, also a good one on the Great 

 Orme's Head. 



Helix caperata, Mont. 



Fairly common. This shell is also found on the Great 

 Orme's Head. 



Helix rotundata, Miill. 



Very common, some specimens being rather large. 



Helix pulchella, Miill. 

 Not very frequent. 



Helix icmhilicata, Mont. 



On the first visit only one specimen w^as found, but since 

 a fairly good number have been taken. 



Buliinus aciitus, Miill. 



Very common. Some of the specimens are very strongly 

 marked and are good examples of the species. They 

 abound in the cliffs all round the island. This shell is 

 very local in its distribution and variable in its markings. 



Bulimus ohscuriis, Miill. 



Only one dead specimen found on the island, but several 

 on the Great Orme's Head. 



Pupa umbilicata, Drap. 



Also very freely distributed all round the island ; there 

 are, however, a good many dead specimens. No other 

 Pupa noticed on Puffin Island or on the Great Orme's 

 Head.
