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 Noi'th 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. "\V. 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 vulf/arix), 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 tine 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. Jefh'eys and Mr. Alder.* 



H. crystallina, Drap,, 

 Is generally distributed in Ireland," occurring in moss, under stones, 

 upon decaying wood, &c., in cky and wet situations, though in the latter 

 more frequently. Some adult specimens which I have collected have had 

 but 3^ volutions instead of 4^ 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 ehurnea subojutca." 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 (jalway, in July, 1840 ; and 

 subsequently in the island of Interlacken, near Roundstone, by Mr. Barlee. 

 Dunscombe's Wood, near Cork, Miss King.
