268 I he Irish Naturalist. 



H. acuta, Miill.— Abundant, along with var. stiigala, Menke., and var. 

 articulata. Lam., on Aranmore, between Kilronan and Killeany. 02curs 

 sparingly on the sandhills at Dog's Biy, and on the fortifications at 

 Athlone. 



H. nemoralis, Miill. — The extreme beauty in colour and variability 

 of banding exhibited by this common species deservedly make it a prime 

 favourite with collectors, and nowhere in the United Kingdom can such 

 lovely examples be obtained as in the West of Ireland. At Gentian 

 Hill, numerous pretty forms were secured, including vars. albolabiata, V. 

 Mart., rubella, Moq., castanea, Moq., and lihdlula, Risso. At Ballyvauglian 

 it attains to great perfection, and many fine examples were taken from 

 the walls surrounding the small fields, but when the weather is dry they 

 retreat far amongst the stones, and require careful search. The shells 

 are of exceptional size and beauty in this locality, some being remark- 

 ably thin and fragile, which at first seems rather strange, considering 

 that the district is on the limestone, and therefore a suitable habitat for 

 snails ; but nearly all the little meadows are formed by covering up the 

 limestone pavement with boggy earth brought from a distance, and it is 

 a well-known fact that snails do not love bogs. This may account for 

 the thinness of the shells, but will not for their large size. The varieties 

 obtained were roseolabiaia, Taylor, albolabiata, V. Mart., rubella, Moq., 

 libellida, Risso., castanea, Moq., hyalozonata, Taylor, and innumerable other 

 intermediate forms of colour and banding. A full account of all the 

 forms obtained here during a four days' visit last year is given in a paper 

 by Mr. Ed. Collier, in The Journal of Conchology, for April, 1895. The 

 greater part of the day on Aranmore was quite unproductive, concho- 

 logically, but the heavy rain which fell towards evening caused the snails 

 to leave their snug retreats in the fern-filled crevices of the limestone 

 terraces, and a number of fine specimens were secured before the steamer 

 started. In their general characteristics the Aranmore specimens do not 

 differ greatly from those [at Ball}- vaughan, except in the remarkable 

 preponderance of white and rosy-lipped forms. Some large semi-fossil 

 specimens from a drift near the priest's house at Kilronan closely re- 

 semble those from Dog's Bay. In the ancient grave3'ard at Clonmacnois 

 some pretty forms occur, notably one in which the bands are all coalescent, 

 and, but for a minute white sutural line, the shell would be perfectly 

 black. It occurs on Inchangoil. 



H. aspersa, Miill. — Common throughout, and remarkable mainly 

 for its extreme uniformity of marking. A few specimens of var. 

 undulata, Moq., were noticed, and five good examples of the pale yellow 

 variety exalbida, Menke, were taken on the terraces and walls between 

 Kilronan and Killeany, Aranmore. 



Bullmlnus ofascurus, Miill. — Very fine under stones on roadside 

 between Athlone and Clonmacnois (Standen). 



Cochllcopa lubrlca, Miill. — Abundant, with its vars. lubricoides,V^r., 

 ovata, Jeff., and hyalina, Jeff. 



Pupa cyllndracea, Da Costa (=P. wnbilkata, Drap.) — Common. 

 On Inis McDara, var. curta, Westl., occurs (Welch). 



Pupa muscorum, Miill. — A few at Ballyvaughan ; Aranmore; Inis 

 McDara ; and Roundstone. 



Vertigo pygriTidsa, Drap. — Common under stones at Aunaghdown, 

 on shore of Lough Corrib. 



V. antivertlgo, Drap. — Several in rejectamenta of River Black- 

 adder, at Ballynahinch. 



Balea perversa, L. — Inis McDara (Welch). 



Clausilfa bldentata, Strom. (=C/. rugosa, Drap.).~Commou in 

 most localities.
