bands that I have seen described, from the hyaline and opaque white to 
the darkest brown. H. ericetorum has in similar variety been procured 
by this excellent and indefatigable collector at the same place, and H. 
Pisana , likewise differing, he possesses from its not far distant station : — 
one of the most beautiful of these three species is opaque white with 
hyaline bands. At La Bergerie, near Portarlington, Mrs. Patterson of 
Belfast obtained a specimen of H. virgata , which both in form and colour 
bears a rude resemblance to the Helix elegans of Brown. 
H. caperata, Mont. 
In Brown’s Irish Testacea this species was noticed to be “ not un- 
common at Naas on mud walls,” p. 526 ; and “ Bullock in Ireland ” was 
given by Dr. Turton as a habitat. (Conch. Diet. p. 51.) The H. 
caperata is in Ireland a very local species, is found in the southern half 
of the island, and appears to be plentiful where it does occur. From 
Dr. W. H. Harvey I had specimens in 1833, which were collected by 
him at Glanmire, near Cork ; on “ dry banks at Kilkee Castle, near Balli- 
tore, County Kildare,” he had likewise procured the species. At Kings- 
town, near Dublin, contiguous to Dr. Turton’s station, it has been col- 
lected by Mr. Warren. At La Bergerie (Queen’s County) it was a few 
years ago obtained in abundance by Mrs. Patterson of Belfast. Among 
the specimens brought from this locality (and presenting gradations in 
colour from the ordinary state to that of being almost wholly of a deep 
reddish-brown) was one shell entirely of a pale amber colour, and trans- 
parent, the fine and regular striae rendering it very beautiful. Here, in 
addition to this species, H. ericetorum and H. virgata were found by Mrs. 
Patterson, and were abundant on the same plant, the H. caperata being 
the most plentiful. 
The distribution of H. caperata seems rather anomalous ; it is unknown 
to me in the North of Ireland, but on the walls of the houses in Portpa- 
trick, one of the nearest parts of Scotland to this country, I have remark- 
ed it; about Ballantrae, in Ayrshire, it has not occurred to me; at the 
base of the cliffs at Salisbury Craigs, near Edinburgh, in 1834, 1 procured 
it in abundance. 
II. ericetorum , Mull. 
This Helix differs from its nearest British allies, H. virgata , H. Pisana, and 
H. caperata, in being pretty generally diffused over Ireland and the adjacent 
islands ; most of the marine sand-banks around the coast claim it, but H. 
virgata in some places appears to its exclusion ; it likewise affects the 
most inland localities, from one of which, near Portarlington, I have spe- 
cimens so large as 9 lines in diameter. An exception to the more ordi- 
nary places of its occurrence may be mentioned ; the ruins of Dunluce 
Castle, situated on the summit of an insulated mass of rock, considerably 
elevated above the sea. In localities in the North, but a few miles dis- 
tant, and in every respect presenting a similar appearance, I have remark- 
ed the specimens in the one to be without exception either uniform in 
colour or very faintly banded, and in the other not one to be of an uni- 
form colour, but all banded, and almost every individual darkly so. Dra- 
parnaud’s H. cespitum, (3. pL 6, f. 15, 17, and Pfeiffer’s H. cespitum, taf. 
2, f. 24, and (3. f. 25, are all very characteristic figures of our H. ericeto- 
rum, as is Rossmassler’s var. f. 516. This author’s H. ericetorum, f. 517, 
a. and b., likewise represent it. My friend Prof. Forbes informs me that 
in the Museum at the Jardin des Plantes, Paris, he in 1838 saw a young
