The Irish Naturalist. 



February, 



is clothed by peat bog. The southern and western flanks 

 of the mountains, especially west of Dingle, are remarkably 

 free from such deposits, the vegetation being mainly com- 

 posed of grasses and Erica cinerea, Calluna vulgaris, and 

 Ulex Gallii. The last mentioned plant gradually disappears 

 at about 1,200 feet alt., above which elevation Juncus 

 squarrosus is a very conspicuous member of the flora. 

 None of these plants is considered a delicacy by land snails, 

 and it is not surprising, therefore, that over large portions 

 of the district Arion ater appears to be their sole represen- 

 tative. 



For the preparation of this list I have visited the district 

 upon three occasions — i8th tih 26th September in 1910, 

 12th till 24th June in 1912, and from 12th till 28th Sep- 

 tember, 1914. Upon the first of these I had the assistance 

 of Mr. Robert J. Welch, M.R.LA., and the following places 

 were searched : — Lough Anscaul, Lough Tooreenmartin, 

 Coumenare, Dingle, Burnham demesne ; the cliffs from 

 Brandon Creek to Brandon Head ; Gallerus and Smerwick 

 Bay ; Kilmalkedar, Inch, Ventry Bay, Slea Head, Connor 

 Hill, Cloghane and Brandon Mountain ; the woods at 

 Fermoyle House ; Stradbally and Castlegregory. On my 

 second trip I visited the Great Blasket and Beginish ; 

 Dingle, Dunquin, Ventry, Kilmalkedar, Brandon Head, 

 Connor Hill, Cloghane and Brandon Mountain, Stradbally 

 and Castlegregory ; and upon my third and last visit I 

 worked Burnham and Dingle ; Ventry, Smerwick, Sybil 

 Head, and Ferriters Cove ; Lough Anscaul, Connor Hill, 

 Brandon Mountain, Cloghane ; Fermoyle and Kilcummin 

 Woods ; and finally the gorge of the Finglass River above 

 Camp, close to Castlegregory Junction. 



Six main types of habitat occur in the district for the 

 land species, and three for the freshwater ones. These 

 may be tabulated as follows : — 



For Land Species — 



Type A. — Cultivated ground ; roadside hedges 

 and banks. 



Type B. — Open ground ; grazed by cattle and 

 sheep, but not cultivated.
