hoe (Co. Tyrone) and at Finnoe (Co. Tipperary), by Edward Waller, 
Esq. ; at La Bergerie (Queen’s County), by Mrs. Patterson and the Rev. 
B. J. Clarke ; and in the neighbourhood of Cork, by Miss Hincks. In 
the North of Ireland the transparent greenish- white var., H. vitrina, Fer., 
as often occurs as the deep yellowish horn-coloured shell. That this He- 
lix is more widely distributed in this country than would appear from the 
above notes, I have no doubt. At Dovedale, in Derbyshire, and Ballan- 
trae, in Ayrshire, I have met with it, and by Dr. W. H. Harvey have 
been favoured with specimens which he collected at the Falls of Clyde 
in 1832. In moist spots, in the wildest and bleakest localities, as well as 
in “ woods,” I have procured it. In the stomachs of four out of seven 
starlings ( Sturnus vulgaris), brought to a bird-preserver in Belfast at dif- 
ferent periods during one winter, I found specimens of this shell, of which 
some were very fine and perfect. M. Michaud, when acknowledging 
specimens which I sent him, remarked that they were a var. of H. niti- 
dula, Drap. 
H. lucida, Drap. 
The H. lucida described and figured by Draparnaud, and characterized 
by Mr. Alder in the Transactions of the Natural History Society of New- 
castle (vol. i. part 1, p. 38), appears to be in Ireland, as in England, 
according to the latter author, “ rare,” and rather a local species. In the 
rejectamenta of the rivers Lagan and Blackstaff, near Belfast, I, in 1833, 
obtained a few individuals, and in Kilmegan bog (County Down) have 
since procured a series containing the living animal. I have seen spe- 
cimens which were collected near Portarlington by the Rev. B. J. Clarke, 
and at Finnoe, in the North of Tipperary, by E. Waller, Esq. Our speci- 
mens differ in no respect from English supplied me by Mr. Alder, and are 
identical with others from Dauphiny, marked “ H. lucida, Drap.,” by 
Michaud, to whom I am indebted for them. 
H. excavata, Bean. 
Of this handsome shell I have yet seen but a single Irish specimen, 
which was obtained at Dunscombe Wood, near Cork, by Miss King, of 
that city. On being shown to the Rev. T. Hincks, he at once identified 
it with H. excavata, and, with the kind permission of the owner, sent it to 
Belfast for my inspection ; it in all respects agrees with English specimens 
of this Helix favoured me by Mr. Jeffreys and Mr. Alder.* 
H. crystallina, Drap., 
Is generally distributed in Ireland,* occurring in moss, under stones, 
upon decaying wood, &c., in dry and wet situations, though in the latter 
more frequently. Some adult specimens which I have collected have had 
but 3£ volutions instead of or 5, the ordinary number. Extensively 
as I have collected this Helix in Ireland, none but dead specimens would 
come under Draparnaud’s var., “ (3 eburnea subopaca .” The animal is of a 
white colour. 
Mr. Alder’s views in reference to the last eight species (Hyalines, Fer.) 
are here adopted ; but even the British species and their varieties belong- 
ing to this division seem not yet to be satisfactorily cleared up. The 
* Helix excavata. Bean, previously noticed as Irish from a specimen found 
at Cork, was obtained by me near Clifden, County Galway, in July, 1840 ; and 
subsequently in the island of Interlacken, near Roundstone, by Mr. Barlee.
