THE LAND MOLLUSCA OF PUFFIN ISLAND. 89 
half way round and two bands on the remainder. Many 
of the living shells are weathered to a greater or less 
extent, which may be accounted for by the very exposed 
situation of the island. 
Helix hispida, UL. 
A few specimens found, also a good one on the Great 
Orme’s Head. 
Heliz caperata, Mont. 
Fairly common. This shell is also found on the Great 
Orme’s Head. 
Helix rotundata, Mull. 
Very common, some specimens being rather large. 
Helix pulchella, Mull. 
- Not very frequent. 
Heliz umbilicata, Mont. 
On the first visit only one specimen was found, but since 
a fairly good number have been taken. 
Bulimus acutus, Mull. 
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. 
Bulumus obscurus, Mull. 
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.
