252 THE SCOTTISH NATURALIST 



Yorkshire, was here quite scarce, except perhaps in one locality, 

 the slopes between the two bridges of Don, Aberdeen South. In 

 every other locality it was found but sparingly, and in many cases 

 it was much eroded. It was noted on both coasts. 



My experience with the genus Helicella was disappointing, and 

 it was only once noted, when I collected H caperata on the golf- 

 links at Belhelvie, Aberdeen South. Mr J. Simpson of Aberdeen 

 told me that it occurs also on the sandhills at St Fergus, but I did 

 not see it there. 



The genus Hygromia was also very sparingly distributed. H 

 fusca is the most generally distributed species in the genus, and 

 was generally found on the leaves of Iris both in woods on the 

 cliffs and on the coast. In odd instances it occurred amongst other 

 vegetation. It also occurred in some of the ravines. H. granulata 

 was only noted on Skye, in both cases amongst old ruins, the ruins 

 of the old churches at Beila Point, Portree, and on the Torran road 

 near Broadford. H hispida I did not see, though in one instance 

 immature dead shells were collected, which appeared very like this 

 species. H rufescens was not observed at all, a strange experience 

 to one accustomed to seeing this species so common in England. 



Acanthinula aculeata I only got in two localities ; on the ruins 

 of an old wall in Kerrydale, Gairloch, and amongst Hairy Wood- 

 rush at Persley by the river Don, Aberdeen South. A. lamellata 

 was the commoner species of the two, and occurred in several 

 localities at Gairloch, Glenelg, and Skye. 



Vallonia pulchella was the only one of the genus noted, collected 

 on the sandhills north of Aberdeen. 



Helicigona arbustorum was found in every place visited, but 

 varied very much in numbers, and was by no means so common on 

 the west as on the east coast. Amongst the taller vegetation on the 

 rocky part of the Aberdeenshire coast it occurred in abundance, 

 but the greater number of shells were immature. 



Helix aspersa was only once noted, and that was amongst 

 nettles alongside the river Don, where it was associated with 

 Helix hortensis. The bed of nettles was at the foot of some 

 allotment gardens on the north side of the river near the Bridge of 

 Balgownie. 



Helix nemoralis was not seen, though Mr J. Simpson has 

 collected it at St Cyrus (Kincardineshire), and he has not seen it 

 anywhere north of that station. Helix hortensis was most sparingly 

 distributed on the west coast, but on the east it was exceedingly
