32 Mr. W.Thompson’s Catalogue of the Land and 
attention in 1832, this Helix has occurred to me in very numerous 
localities throughout the counties of Down and Antrim, in the 
county of Londonderry, and in the glen of the Downs in Wicklow. 
By Mr. Harvey it was sparingly found several years ago on the ma- 
rine sand-hills at Miltown Malbay (county Clare); more latterly by 
Mr. E. Waller of Dublin, at Annahoe (county Tyrone), and by the 
Rev. B. J. Clarke, near Portarlington (Queen’s county). At Twizel 
House, Northumberland, and Ballantrae, Ayrshire, I have collected 
this species. Draparnaud’s description and figure of H. pygmea 
are most characteristic.

Although not an abundant species anywhere, is generally distri- 
buted over Ireland and her islands. From under stones at the sea- 
side to a great elevation on the mountains,—as near the summit of 
Divis, the highest of the Belfast chain—of Altavanagh, one of the 
mountains of Mourne in Down, and of Ben Bulben in Sligo, I have 
met with it—all situations, from the exposed sea-shore and mountain 
side to the umbrageous wood, seem alike to it. A greenish white 
variety, and the shell strong, is much more common in Ireland than 
the yellow, which is ranked the ordinary state: from under the same 
stone I have procured specimens of both colours. The animal is 
blackish. M. Michaud remarked, on acknowledging Irish specimens 
from me, that they were H. nitida, Drap., junior.

Helix nitida, Drap. p.117. pl. 8. f. 23—25. 
Is common, and distributed over Ireland. It has a predilection for 
wet situations, and even from the bottom of drains, partially co- 
vered with water, some of my largest specimens were procured in 
the north; the very largest Irish specimens—7é lines in diameter— 
I have seen were found in drains within the city of Dublin, by Mr. 
T’. W. Warren, to whom I am indebted for them. From the sto- 
machs of the Blackbird and Starling I have taken perfect specimens 
of this shell. 
25. Helix pura, Alder. ‘Turt. Man. p. 59. 
Zonites purus, Gray, Man. p.171. pl. 4. f. 43. 
Is distributed over Ireland; it is usually found in moss, under 
stones, &c., in sheltered situations, but on sea-side pastures likewise 
I have met with it. The yellowish horn-coloured variety has in all 
parts of the country occurred to me more commonly than the hya- 
line shell: the closely set, regular, and fine striz render recent shells 
of this species very beautiful. M. Michaud, on acknowledging Irish 
specimens of H. pura, observed that they were HH. nitidula, Drap.
