Dublin to Galway ; and while it seems 

 to be absent from tte coast of North 

 Kerry and Clare — sand-dunes included 

 — it is found inland at Ennis, in the 

 latter division. Though absent from 

 Clare Island in "West Mayo, it is as a 

 general rule found on the western 

 islands, and is also recorded from 

 Lambay in Dublin, and Rathlin in 

 Antrim. Its variation is considerable, 

 both in size and markings; but nowhere 

 is such great variation observed as on 

 the east coast from Dublin to Down, 

 where specimens can be found from 

 almost white to black. In the central 

 districts and on the west coast the pre- 

 vailing forms are the type and var. 

 strigata. while examples from many of 

 the western islands are of a much more 

 tumid shape than is usual on the 

 mainland.

Fairly common throughout the native- 

 wooded areas and in similar uncultivated 

 parts of the country, but especially 

 abundant in the damp northern and 



western glens ; and its almost constant 

 association with the Wood Rush {Luzula 

 maxima) is remarkable. It is absent 

 from many districts in the central 

 counties, and is always rare outside 

 the coastal or mountainous parts of 

 the country, but shows no preference 

 for any geological formation. Its pre- 

 sence on the sea-cliffs of Achill and 

 Clare Islands in West Mayo is parti- 

 cularly interesting ; but since this shell 

 is known to be a very ancient species, 

 the fact is not so surprising. In the 

 Dingle peninsrila, in South Kerry, it 

 occurs on Luzula to at least 1400 feet 

 altitude near Connor Hill, closely asso- 

 ciated with such local plants as Saxifraga 

 umbrosa, S. Geitm, S. stellaris, Oxyria 

 digyna, and Pin(juicula grandiflora.

Has mainly a south-western range, 

 and, tliough local, is generally plentiful 

 where found. Mr. Phillips sends me 

 the following notes on its habits : —
