1909- Sthlfox. — Mollusca of N.IV. Donegal. 87 



Donegal, but it nowhere appears to predominate as atTramore. 

 Mr. Collier and I, not being '• pot hunters,' left the party at 

 the kitchen middens and worked on to PoUanguil Bay, where 

 on my previous visit I had taken a large and very lieav}' and 

 thick form of /A7/.V }ici)ioraIis living on the flat sandy area 

 close to the sea. There is absolutely no cover for anything 

 where these shells are living, and we observed many specimens 

 in the act of appearing from the sand into which they had 

 burrowed to escape some climatic condition which did not 

 suit them. Here also we found Helix iiitersecla in fair 

 abundance, and apparently more at home than in the other 

 locality mentioned above. Xew records for Horn Head were 

 Avion inteiinediiis and Pupa nmsconini, while a ver}- small form 

 of Clansilia bidentata was worth noting. 



In the afternoon some collecting was done in the neigh- 

 bourhood of Dunfanaghy by Messrs. Chaster, Wright and 

 Milne, who noted the following species new to the locality : — 

 From Kill I^ough. Linnuca lucj iiiila?ia var. aeiiia., and 

 L. paluslris \ from moss shakings collected above Kill I^ough. 

 Hyalinia piira, //. crystallina. Helix aculeata, H. lamcllata : 

 from Sessiagh I.ough, a shell identified by all of us as 

 Hydrobia ulva' was taken by Mr. Milne. The operculum was 

 in position, but the specimen was unfortunately lost before 

 we had the opportunity of proving if the animal was alive or 

 not. Sessiagh Lough is a considerable distance from the sea 

 and at an altitude of 96 feet above it, it is therefore strange to 

 find this brackish water species in such a position. 



7th September. — Leaving Messrs. Chaster, Collier and 

 Wright at Dunfanaghy, the remainder of the jiarty left early 

 in the morning to proceed to Bunbeg, but after driving for six 

 miles in torrential rain we were held up by the floods descend- 

 ing from the adjoining hills into the valley at Ballymore, which 

 was deeply flooded, both roads being under five to seven feet 

 of water at this point. There was no choice but to retreat, 

 which we did in good order, bringing with us large quantities 

 of the rejectamenta floating along the margin of the flood, 

 containing many .species of beetles and other in.sects, as well 

 as some land shells, among which were a good man}- Helix 

 fusea^ //. nemoralis, H. erieetoncm and H. hispida, all alive, and 

 one dead specimen of H hortensis of the type.
