Helix rupestris, Drap. Hist. des Moll. 82. 
Animal fusco-nigricans. Tentacula inferiora tuberculiformia. 
Habitat in rupibus, preesertim in subalpinis, vulgaris. 
Shell brown, the whorls transyersely striated finely, the aper- 
ture nearly circular. Longitudinal diameter one-eighth of an 
inch. 
The suture between the whorls is deeply marked, and the 
apex moderately produced. 
Inhabits rocky places, especially such as are of a considerable 
degree of elevation. I have observed it near the summit of 
Ceim-na-cailich, on the Ranza side of the Garbh-Chorie, in 
Arran; and at a similar elevation on Bhein Gaodh, in the same 
island. 
It occurs in great abundance on the rocks and stone walls 
that skirt the low mountain-plains, in the vicinity of Chelten- 
ham; on the borders of Dartmoor ; “on the summit of the hill, 
in Portland Island ;’? on houses and old walls near Lackham, 
in Wiltshire; and on the Reeks, near Killarney. 
The Rev. Revett Sheppard has communicated to me a minute 
variety of this species, under the name of Helix elegans, that 
scarcely exceeds the 20th of an inch in diameter, and which 
has never been found of larger dimensions, although it is very 
abundant at Wrabness, in Essex. I can find no difference be- 
tween it and the young of Zonites rupestris. 
Animal blackish, inclining to fuscous. Lower tentacula tu- 
berculiform.
