PULMONATA. 
Family: LimMacipa. 
Limax agrestis, Mull. 
Very common, especially after rain. No other slugs 
have been observed. 
Family: HELIcIDz. 
Vitrina pellucida, Mill. 
Only a few specimens found. 
Zonites cellarius, Mull. 
Fairly common, some good ones. No other Zonites 
found on the island, but another species, Z. alliarius, 
Mill., was obtained on the Great Orme’s Head, when one 
Specimen only was found. 
Heliz aspersa, Mull. 
It is a strange fact that this common shell should only 
be represented by dead specimens, not even a single living 
one having been found on the island. The quantity of 
dead ones is very large, showing that the species must 
have been very common formerly. Most were found at 
the mouths of the rabbit holes. Both on Anglesey and 
the Great Orme’s Head living specimens are found. 
Helix nemoralis, Li. 
By far the most common land shell on the island, and 
some are very good examples. The Conchological Society 
of Great Brita and Ireland are now making each 
differently banded shell a distinct variety, which is to my 
mind a great mistake. The number of bands and colouring 
of this shell is certainly too slender ground to go upon in 
forming named varieties. Some shells have only one band
