12. H. HORTENSIS (¢zhabiting gardens), Miller. PI. IL., f. 19. 
Differmg from A. zemoralis by its smaller size, more globular 
form, and relatively greater solidity ; typical banding the same as in 
fH. nemoralis ; outer lip and columella usually white ; ter ip exces- 
sively thin and coloured or banded like the rest ot the shell; azzmal 
usually lighter in colour than wzemoralts ; dart curved, length 4mm. 
A. 16mm. B. 18mm. 
Hf, hortensts, long a disputed species, has now been 
definitely separated from 7. xemoralis. Its name horten- 
sts (the garden snail) is as inappropriate as that of the 
last-named, since it rarely frequents gardens. 
Though its range is not quite so extensive as 7. memo- 
valts in England, Ireland, and Wales, it is of wider distri- 
bution in Scotland and will probably be found in every 
comital area in that country. 
The two species are by no means invariably associated 
even when occurring in the same district, though occa- 
sionally, asin the limestone region of Derbyshire, they 
both swarm over the “tors.” On sandhills near the sea, 
where zemoralts is usually abundant, Zorfensis is rarely, 
if ever, found. It varies in colour almost as much as 
nemoralis, but not concomitantly, the albino form, for 
instance, being much more common in “ortensis. 
With a little experience it may usually be distinguished 
from xemoralis by its general appearance; and it is a 
general, though not a universal rule, that, whereas white- 
lipped examples of zesoralis are yellow (resembling the
