it may be only a " garden escape." All the examples in the last locality 

 were of the very black form, with bright orange foot-sole.] 



A. circumscriptus Johnston. — N. Frequently met with, but always rare. 



Punctum pygmaeum Drap. — N.S. Local, and does not appear to lie 

 plentiful. 



Sphyradium edentulum Drap. — N.S. Probably generally distributed. 



Pyramidula rotundata Mull. — N.S.W. Generally distributed up to 1400 feet 

 altitude, except on the peaty areas. 



Helicella itala L. — N. Abundant on all sandy areas. 



H. barbara L.— N. Common at Keel Strand, at Dugort, and on the warren 

 at Valley, though recorded by J. G. Milne only from the last station 

 and regarded by him as a new-comer. 



Hygromia hispida L. — S. Not mentioned by J. G. Milne, and appears absent 

 from the greater part of the island. It is, however, common along the 

 shore at Kildawnet. 



[H. rufescens Pennant. — N. Still in Milne's station in the gardens at 

 Dugort, and, as he suggests, is undoubtedly an artificial introduction. 

 Also occurs on the refuse-heaps in the village of Valley.] 

 *H. fusca Mont. —Abundant on the cliffs- — on clumps of Lunula maxima— 

 at 800 feet altitude, above the eastern Lough Nakeeroge. Also occurs 

 almost at sea-level on the cliffs a quarter of a mile east of the village 

 of Dugort. 



Vallonia pulchella Mull. — N. Frequent and common on the sand-dunes. 



Helix aspersa Mull. — N.S. J. G. Milne regarded this species as probably a 

 recent introduction; but from its almost universal occurrence on the 

 western islands, I think it has an undoubted claim as a native. There 

 is always the chance, however, that this shell may have been 

 introduced by primitive man as an article of food. It is more widely 

 distributed on Achill than Milne appears to have been aware of, and 

 occurs not only at Keel, but also at Dooagh ; while it is abundant in the 

 southern portion of the island at Kildawnet. 1 



H. nemoralis Mull. — N.W. Considered by J. G. Milne as dying out on 

 Achill— an opinion which is probably correct. Besides the only station 

 mentioned by Milne — Ship Point — it still survives on the sand-dunes 

 near Lough Nambrack ; on the cliffs, close to the sand-hill deposits, at 

 Dugort ; and on the cliffs to the east of the eastern Lough Nakeeroge, 



1 In a former paper (Proceedings R.I. A., vol. xxix, Section B, No. 3, p. 93) I quoted Mr. J. G. 

 Milne as saying " that this shell is apparently losing ground in certain localities, and that it was 

 seemingly extinct in Achill." I regret that this note appeared under H. aspersa, as it really referred
