191 5- STEI.FOX. — MoUusca of Dingle Promontory. 23 j 



that any large species could exist in Kerry and yet have been \ 



overlooked by the various naturalists who have collected j 



there. Yet the occurrence of Fiona quimperiana, a land- j 



shell whose continental range is so similar to that of several ! 



species of plants and animals which occur in the south-west | 



of Ireland, is not beyond the bounds of possibility. It ; 

 is strange, too, that this Pyrenean shell should have a 



somewhat superficial resemblance to Planorhis corneus. ■ 



Monsieur Bourguignat, in his work on the Mollusca of ] 



Brittany, 1 states that Elona is most common on damp . 

 days in June, and that it lives in humid and shady places 



under decaying timber near streams or in woods. The most ; 



likely habitat for this species would be, I imagine, in the ] 

 woods round the southern shore of Caragh Lake. This is 

 close to the spot where Andrews first discovered Geomalacus 



maculosus in the year following that mentioned in Robert ■ 



Callwell's note quoted above, namely, 1842. ] 



It will be noticed in the list given below that several of 1 



the more local shells are recorded from Glenfahan, near Slea | 



Head. This is in reality not a glen in the ordinary sense ■ 



of the word, but merely a small gully or stream -bed cut by ; 



a tiny rivulet. In one spot for a few yards along the southern i 



side of the stream, shaded from the sun, there is a luxuriant | 



growth of ferns and mosses. In this habitat a true \ 



" woodland" fauna was found, the following species being i 



noted :—Agriolimax agresiis, Hyalinia cellar ia, H. pur a, \ 

 H. radiatula, H. crystallina, Arion suhfuscus, A. intermedius, 

 Punctuni pygmaemn, Pyramidula rotundata, Acanthinula 



aculeata, A. lamellata, Helix nemoralis, Cochlicopa luhrica. j 



Pupa anglica, P. cylindracea, Carychium minimum, and | 



Acicula lineata. I have but little doubt that the fauna j 



represented at Glenfahan had an almost universal distribu- \ 



tion during the post-Glacial " Forest Period " — the climatic i 



optimum — which is now so generally recognised to have ; 



existed. j
