120 LAND AND FEESH-WATEE MOLLUSKS. 
Belfast, once found a spiculum of H. nemoralis 
stuck through a dandelion leaf. 
The garden snail is the most prolific of the 
Helices , depositing from 100 to 110 eggs. The 
spot selected for the purpose of depositing these 
is under a stone, or piece of decaying wood, 
lying in some damp and unfrequented part of 
the garden, or it may be buried in the moist 
soil. The young snails appear at the end of 
from fifteen to thirty days, and at the end of the 
autumn are about the size of a hazel-nut, and 
attain their adult condition in the latter part of 
the following year. 
Helix nemoealis — (the Wood Snail) (PL 
VII., fig. 45).—The shell of this snail is familiar 
to all, and is one of our prettiest. It is either of 
a yellow or chocolate-brown, encircled with from 
one to five brownish spiral bands; of a globular 
form with a roundish aperture; the reflected 
margin is brown; the diameter is not quite an 
inch, and the height is about three-quarters. 
The jaw of this snail is strongly arched, and 
marked with fire longitu¬ 
dinal ribs, which indent the 
edges of the plate. The 
lingual ribbon contains 135 
rows of 100 teeth each.
