HELICIDJE. 
In woods, among decayed leaves, and under 
stones. {Fleming^ 1809.) 
Animal light-coloured above, with black head and 
horns ; under part light-coloured, bordered with 
black; air-valve, when closed, with a black spot, 
when open, surrounded by a black ring. {^Sturm^ 
Fauna, t. 9. ; Pfeiffer, 1. c.) 
Shell half an inch in diameter, not so much in 
height, extremely thin and transparent, of a pale 
watery green, and quite smooth; volutions three, 
the first very large and a little oblique, the others 
but little raised and ending obtusely ; aperture very 
large, oval-elliptic, rather oblique, interrupted at 
top by the prominency of the second volution, with 
the margin thin and membranaceous, often coloured 
with a pale brown border, without internal rib ; the 
suture well marked, and when magnified exhibiting 
a striated spiral line ; pillar lip a little reflected, and 
forming a slight concavity, but not an umbilicus,

some this is whitish and more wrinkled than in 
others, in some it is brown, whilst in others the

2. The green colour of the shell also varies in 
hue.

it as British in 1819, and it was noticed as English 
by M. Ferussac and myself in 1820 and 1821.
