40 Beautiful Shells. 
But let us return to our Garden Snail, who 
has many near relatives in Britain, several of which 
have beautifully-marked and convoluted shells, as 
will be seen by a reference to our coloured illus- 
trations, Plate I. We will introduce them in due 
order. Fig. 1, the Banded Snail (Helix nemoralis), 
from the Latin nemus—a wood or grove; the 
prettily-striped shells of this species may be found 
in great plenty among the roots and in the crevices 
of the rugged boles of old forest trees, as well as 
in hedge-rows and in mossy banks, and other 
situations near woods. Fig. 2, the Heath Snail 
(H. ericetorum), from erica, the Latin for heath; 
a small species with brown bands, remarkable for 
its large umbilicus, perforating the centre of the 
shell nearly through. Fig. 3, the Silky Snail 
(Hf. sericea), from the Latin sericus—silk-like ; 
the shell of this species is covered with short 
slimy hairs, which give it a glistening appearance. 
Fig. 4, the Stone Snail (H. lapicida), from the 
Latin lupis—a stone: Linneus called the species 
the Stone Cutter, probably on account of its habit 
of frequenting stony places, and the peculiar 
construction of the shell, which has a sharp 
edge running round each whorl; it is commonly 
found lodged in the cavities of loose-lying stones,
