llelix aspersa. Very abundant. I found one specimen considerably longer in pro- 

 portion and marked with five distinct bands. 

 „ nemoralis. Very abundant, and varying considerably in size, and in eleva- 

 tion of the spire. The lip of different colours, from pure white, through 

 various shades of rose and brown, to nearly black. I have collected spe- 

 cimens corresponding very well with the figures in Turton, of H. nemo- 

 ralis and IT. hortensis, and with most of the figures in Brown, of H. 

 nemoralis, hybrida, and hortensis. None were as small as the figure of 

 hybrida in Gray's Turton. I have collected, at Manheim, on the 

 Rhine, Helices, with black and white mouths, plain and variously banded, 

 but all smaller than our hortensis, and some precisely like the figure of 

 H. hybrida, in Turton, p. 11, fig. 130. I obtained, from the late Mr. 

 Thompson, a specimen of Mr. Leyland's H. hybrida, from Halifax ; it is 

 smaller than the figure in Turton, and, at least in size, cannot be con- 

 sidered intermediate between nemoralis and hortensis, being very much 

 smaller than either From having collected these shells in various parts 

 of Ireland and in England, I think the mere shell will scarcely afford 

 sufficient means of indicating different species ; a specific difference in 

 the animal would, of course, be decisive. For such purpose, the variation 

 in the Vesicula multifida should be proved to be constant, by an extended 

 examination of specimens from various localities. Even then, unless it 

 could be shown to produce sufficiently distinct characters in the shell, 

 it would not avail the collector or conchologist. 

 ,, pulchella. Rare and local. I have obtained both the plain and ribbed 



varieties in high, dry grounds, and also in marshy situations. 

 „ fusca. Rare ; in Borris Wood. 

 „ fulva. Rare ; normal in shape. 



„ hispida. Common ; varying much in colour, height of spire, and close- 

 ness of hairs. Some of these shells may be H. sericea, but I could not 

 satisfactorily draw a line separating some of the varieties of H. hispida 

 from shells better answering the description of H. sericea. 

 ,, concinna. I found this species, as determined by Mr. Thompson, on exami- 

 nation of the shells. 

 „ rufescens. Not uncommon ; pale ash colour, and dark brown. 

 „ virgata. Pale ash colour, and white, with a single dark band ; very 

 abundant in one locality only, where I have reason to believe that it 

 must have been recently, and I should say accidentally, introduced; and 

 that I observed it very soon afterwards, when specimens could not be 

 found beyond the range of a few yards, although, a few years after, they 

 were so numerous, over whole fields, as to be crushed at every step. Helix 

 ericetorum was plentiful in the same fields. 

 „ ericetorum. Extremely abundant over the whole district generally, with 

 one or more brown bands ; sometimes mottled with brown ; rarely white, 

 with transparent bands. 

 Zonites rotundatus. Plentiful, varying but little in form. 



„ umbilicatus. Extremely numerous on dry walls and limestone rocks. 



» pygmaeus. Very rare and local ; at Kyle Park. 



„ alliarius. Not numerous ; obtained both of the horn colour and pale green. 

 I have procured a few specimens of a larger Helix, nearly crystalline ; 

 they were shown to Mr. Thompson, and noted by him in his catalogue 

 as intermediate in form between H. nitidula and H. alliaria; could they 

 be H. glabra, of Studer — var. 2 of Gray's Turton ? 



„ cellarius. Common ; generally distributed ; not exceeding one-half inch 

 in diameter. 



,, purus. Not common, but found both hyaline and horn colour. 



„ nitidulus. Common. I have found a few shells, smaller, whiter, and 

 more transparent ; not having seen any description of Mr. Gilbertson's 

 H. helmii, I cannot say whether they resemble it. 



,, radiatulus. Rather rare ; occurring hyaline and horn-colour. 



„ lucidus. Rare and local ; at Finnoe.
