35$ The Irish Naturalist. December, 



Helix rupestris, Drap.— Abundant and generally distributed, but was 

 not taken further west than Ballynaliinch. The var. viridescenti-alba 

 was taken on a wall under trees near Kilrouan, on Inishmore. 



H. rotundata, Miill. — Common on Inishmore and Inishmacdara, as 

 well as all localities on the mainland. 



H. pulchella, Miill. — Generally common, most of the specimens being 

 referable to H. excoitrica, Sterki. The var. cosiata was taken sparingly 

 at Gorteeu Point, together with an abundance of the type. The 

 type was observed on both Inishmore and Inishmacdara. 



H. aculeata, Miill — Occurred in moss shakings from Kilbeg, Ross, 

 and Gorteeu Point. The var. albida was seen at Kilbeg and Cregduff. 

 On the shore of Cregduff Lough I took several specimens without 

 spines. This form does not seem to have been described by any of 

 our authorities as a variety, though it is probably common, as 1 

 have taken it in several other localities, though, strange to say, 

 always in exactly similar situations, i e., on lake shores under stones 

 just above Ihe level of the w T ater, and usually in company with 

 Vertigo antivertigo, Succinea e/egans, and Litnnaa truncatula. 



H. Iamellata, Jeff. — Under dead leaves and on the trunks of trees in 

 the old woods at Kilbeg, Ross, and Ballynaliinch. 



H. hispida, L. — Kilbeg, Clare-Galway, Ross. Roundstone, Inishmore, 

 and Inishmacdara. Fairly common, but not nearly so plentiful as 

 the next species. 



H. rufescenSi Penn. — Common everywhere, including Inishmore. 



H. f usca, Mont. — Plentiful in the old natural woods at Kilbeg, Ross, 

 and Ballynaliinch, 



H, virgata, Da Costa. — Found everywhere, except at Ross and on 

 Inishmacdara, the commonest forms being the type and vars. 

 lutescens and albicans. This shell was extremely common on Inish- 

 more. Two specimens showing extended lips were taken at Dog's 

 Bay, where a colony of very high-spired shells were living. 



H. intersecta, Poir. — Apparently the rarest xerophile in the district, 

 but occurred sparingly at Kilbeg, Ballindooley, Ross, Galway, 

 Coolagh, and on Inishmore. 



H. ericetorum, Miill.— Very common everywhere, including Inish- 

 more and Inishmacdara. As usual, this species showed marked local 

 variation, the more inland specimens being flatter and larger than 

 those taken in the coast sand-dunes. Mr. A. S. Kennard was greatly 

 surprised on seeing some of these latter from Inishmore, as they are 

 Strikingly different from the large flat form found in the south-east 

 of England. 



H, acuta, Miill. — Common on the sand-dunes at Dog's Ba} T , on Inish- 

 more, and Inishmacdara. This species also occurred at Coolagh, 

 which is well inland. 



H. nemoralis, h. — Common in most of the localities visited, includ- 

 ing Inishmore and Inishmacdara, and like H. ericetorum showed great 

 local variation ; for example, all the specimens taken on Gorteeu
