3. Helix nemoraliSj or the Helix of the groves, is a 
shell considerably smaller than the foregoing, also 
globular with an infinite variety of coloured bands 
running parallel with the whorls. It is perhaps the 
commonest of all the Helices, frequenting woods, 
gardens, hedges, and walls everywhere, and there is 
no difficulty in distinguishing it after a shower of rain, 
when the animal is met with in dozens cropping the 
freshened vegetation. The ordinary shell has a black 
lip, but in the variety hortensis it is white, which 
distinction has led to the latter being considered a 
species. This variety has been detected about Barn¬ 
hill, and wiU no doubt be found in other parts of the 
county. 
4. Helix arhustorum, or the Helix inhabiting 
copses, has a shell rather larger than the former, 
globular, solid, of a yellow-mottled with-brown 
colour, and a single brown spiral band round the 
middle of each whorl. I consider this shell the 
prettiest of the genus. The animal inhabits moist 
and shady woods, hedges, and ivy banks. It is 
found at Barnhill, in the Den of Pitroddie, Glenfarg, 
and very generally in the Perth district. I have a 
specimen from the Hill of Tulloch at Blair Athole, in 
which the shell is much smaller than usual, and the 
spire more raised. I take it to be the variety 
alpestris of Jeffreys. Dr Buchanan White tells me 
he has spec’mens of this variety from Barnhill. 
5. Helix concinna, or the neat Helix.—This shell 
is much smaller than the nemoralis, and about the 
size of a pea, roundish and rather flat, light grey with 
reddish brown streaks. The epidermis is covered 
slightly with short white hairs, which are easily shed. 
This shell seems to be very common in this district ; 
and, indeed, according to our President’s statement 
(who has gathered it often) it would appear to be 
more abundant than the hispida, to which it has a 
very great resemblance. The stations recorded are 
KinnouU Hill and Barnhill, although it will no 
doubt be met with in many other localities. 
6. Helix hispida^ or bristly Helix.—Shell same 
size as last, but not so much flattened, the umbilicus 
larger, and the bristles less scattered and more per^
