HELIX NEMORALIS. 297 
The sub-var. lueifuga is described as gigantic, fasciate, or unbanded, scrobieu- 
late, malleate, with transverse and spiral striation; aperture liver coloured, and rib 
pale flesh coloured, or rib purple and margin black, and figured as 85 mill. in diam. 
The sub-var. galliea is of maximum size, variously faseiate, aperture white, 
or rarely with lip white, and rib and margin purple. Diam, 32-33 mill. ; alt. 20-23 mill. 
The sub-var. etrusea is large, distinctly striate, and irregularly but minutely 
malleated. 
The H. nemoralis var. appenina Stabile, H. genuensis Porro, and H. etrusca 
Lessona are given as identical, Lessona quoting the dimensions as 30 mill in 
diam., and 20 mill. in alt. 
In the larger specimens, especially of the gigantic continental varieties, the 
sculpture of the shell becomes strongly serobiculate, and presents a very different 
aspect to the simple striation of the ordinary British form. 
Bouchard-Chantereaux has observed that shells obtained from the cliffs about 
Boulogne are unusually fine, being nearly twice the size of specimens found else- 
where in the district. 
In many places on the west coast of Ireland, as at Valentia and on the Aran 
Isles, there is, according to Dr. Scharff, a race of very large forms.
