lu order to be quite sure that we were uot dealing with Helix horiensis, 

 which has been recorded from some of the Scotch western islands, 

 probably in at least a few cases erroneously, we examined the darts of 

 those specimens which most nearly resembled that species. In all cases 

 these darts were quite typical of Helix nemoralis. 

 Cochllcopa lubrica, Mull.— Cliffs at east end only. Normal. 

 Pupa cyllndracea, Da Costa. — Very abundant on the cliffs, and a few 

 in Legreh}'. The predominating form is that which is common to 

 all the western Irish islands from which we have seen specimens, 

 and appears to be the Pupa anconostoma of Lowe,^ first described by that 

 authority from the Atlantic Islands, and now considered as a mere 

 \a.Y\ety oi Pupa iylinch-acea. None of the Tory specimens were quite 

 edentate, but in all cases the denticle was very small. Of specimens 

 of this species^ taken on St. Kilda, Messrs. Waterstou and Taylor 

 give the following note : — " Singly, and in small colonies every- 

 where, all the edentulous form and probably the same as the Pupa 

 senipronii of Switzerland." 

 Pupa angelica, Fer. — Of the large dark "marsh" form, about six 



specimens were taken in I^egrehy at the roots of the vegetation. 

 Clausilia bidentata, Strom.— One half-grown dead shell on the 



south cliffs at the east end. 

 Limnaea peregra, Miill. — A small form common in Lough Ayes and 

 the neighbouring pools. The largest of the specimens measured 

 about 10 X 7 mm., and all might be referred to a form of the var. 

 Boissyi. 

 L. truncatula, Miill.— Abundant around the margin of Lough Ayes. 



A short and stumpy form. 

 Planorbis crista, L. — Small specimens in a pool between L. Ayes 

 and the Light-house. 

 A few notes on the distribution may be of interest. Of the 

 species recorded by us only one, Pupa anglica^ has not a wide 

 range in Europe ; all are usually to be found on the Irish and 

 on some of the Scotch islands, and 13 of the 17 land-shells are 

 common to Tory and St. Kilda ; 6 are recorded for the Shet- 

 lands, 4 for the Faroes, 4 for Iceland, 2 for Greenland, and 4 

 for North America ; while 9 are also known to inhabit the 

 Atlantic Islands. 



Returning to our work on the mainland after an " all night 

 sitting," neither of us were in the best hunting form when we 



1 P.cylindracea var. anconostoma is recorded by Dr. Scharff (/. A^., vol. vii. 

 p. 10), from the Great Skellig in South Kerry.
