REPORT on the LAND MOLLUSCA of PUFFIN 
ISLAND. 
By ALFrep LEICESTER. 
[ Read 13th December, 1889.] 
In presenting this report on the land Mollusca of Puffin 
Island, I may remark that on account of the small size of 
the island the numbers to record cannot possibly be large, 
or the species very varied, still what species have been 
found are well represented. The collections were made in 
the autumn of 1887 and summer of 1889. Further time 
devoted to the search in the future may result in the 
discovery of a few additional forms, but it is not to be 
expected that many such will be found. So far two 
families only are represented, viz. Limacide by one species, 
and Helicide by fifteen species. 
I have not yet made a very careful search on the main- 
land of Anglesey, around Penmon Point, or on the Great 
Orme’s Head, but most of the species found on the island 
have also representatives on the mainland; whilst one 
noticeable form found commonly on the Great Orme’s 
Head does not occur on the island, viz. Cyclostoma elegans, 
the only operculated land shell. It seems strange that 
not even a dead specimen should have been found on 
Puffin Island considering its proximity to the land, and 
this being so, it would appear that no communication can 
have existed for a long period, or else such a striking form 
would surely have left some trace. 
The nomenclature I have used is that of Forbes and 
Hanley’s “ British Mollusca,”’
