3^ 2 The Irish Nahualist. December, 



Anodonta cygnea, L.— Dead shells from the shore of Lough Ross 



were the only indication we had that this shell was to be found in 



the district. 

 Pisidlum nitldum, Jcnyns.— Rare, and seen only in Ballindooley 



Lough. 

 P. forttinale, C. Pfr.— Common at Kilbeg, Ballindooley, Cregduff, and 



Maumeen Loughs. 

 P. milium, Held.— Kilbeg, Ballindooley, and Roundstone. 

 P a obtusale C. Pfr. —Apparently rare and local: — Ballindooley and 



Maumeen Loughs. 

 [P. pulchellum, Jenyns. — Found by Mr. Standen at Annaghdown, 



Lough Corrib, in 1895J. 

 P. pusillum, Gmel.- Common at Kilbeg, Ballindooley, Roundstone, 



and Maumeen. 



Iii the above list of 85 species 80 were collected on the lime- 

 stone and 64 on the granite area. In a paper on the mollusca 

 of this district, published in the Journal of Conchology, vol. viii., 

 p. 177, Messrs. Collier and Standen state that the collecting 

 '•proved to be of a somewhat unpromising character con- 

 chologically, whenever we got off the limestone." The above 

 figures will, I think, show that this is not strictly correct. 

 With regard to the mollusca at present living at Dog's Bay, 

 Messrs Collier and Standen stated in 1895 they could find 

 only four species — H. aspcrsa, H. huetorum, H. acuta, and P. 

 muscotum — on the sand-dunes and promontories composing 

 this locality, although the search was carried on in very 

 favourable weather. This seems very strange, as on this 

 occasion we obtained 33 species living in this very restricted 

 habitat : several species, such as Helix vhgata, H. nem oralis, 

 and various Vertigoes being in great abundance. 



I have to thank Mr. Charles Oldham for identifying the 

 Pisidia, Mr. J. W. Taylor, F.L,.S-, Mr. R. Welch, M.R.I. A., 

 Mr. A. S. Kenuard, F.G.S , and also the other members 

 of the party for their assistance in preparing these notes. 

 Below are lists of localities, showing the county divisions in 

 which they come, and list of species found in each division. 

 In these I have followed Mr. Praeger's division of Ireland. 

 Species for which I can find no previous record are marked *, 

 while those in brackets have been recorded but were not found 

 by our party on this excursion.
