the animals for shelter under stones and into rock crevices, 

 and it required much labour to get at them in their 

 retreats. 



H. hortensis Miill. — Scarce. A few weathered specimens near 

 DunoUie Castle, and on road to Loch Etive were all we 

 noticed. 



H. arbustorum L. — Very fine in woods behind Oban, and 

 near the Manor House. Mostly a very dark coloured and 

 high spired form. Mature specimens were very scarce, 

 but young shells occurred in profusion. On Lismore we 

 took one solitary specimen — variety inarmorata Taylor — 

 amongst nettles at foot of an old wall. 



H. rufescens Penn. — A dark compact form was fairly common 

 about Dunollie Castle. One specimen of variety alba 

 Moq. was taken at Ardbhan Craigs, but the type was not 

 seen in this locality. On Lismore it is rather scarce, 

 typical in form, and very large. 



H. hispida L. — Very rare, only a few of the type were found, 

 close to Oban. 



H. sericea Jeff. — The commonest Helix found thronghout the 

 Oban district ; also on Lismore, where it is remarkably 

 fine. Both type and var. cornea Jeff. 



H. ericetorum Miill. — Plentiful on the island of Lismore, 

 but we did not see any on the mainland. Extremely 

 variable in size and markings. The small dark-banded 

 form which corresponds to Westerlund's H. lampra was 

 not uncommon, and as far as our experience goes it appears 

 to be exclusively a maritime variety. 



H. caperata Mont. Not uncommon on grassy slopes on Lis- 

 more. Type and variety ornata Picard. 



Pupa anglica Fer. — This was found very plentifully under 

 stones at Ardbhan Craigs, chiefly along the edge of the 

 pine woods, and close to the roadside, wherever the ground 

 was wet from the trickling of water down the cliffs. Mostly
