HELIX. $a 
yellowish horn-colour; striated finely and regularly in the 
line of growth ; whorls four, cylindrical; spire more or less 
raised ; wmbilicus large. 
This is the smallest of the Helices. It frequents 
moist situations in woods and under hedges among dead 
leaves. A good plan that saves much time is to take 
a quantity of dead leaves home, and after drying them, 
to examine the siftings. 
H. pygmea is a very pleasing object under a powerful 
lens—the close-set, well-marked striz appearing as a 
surprise to the observer. 
22. H. PULCHELLA (minutely beautiful). 
Nearly circular, rather solid, semi-transparent, white ; 
whorls three and a half; mouth nearly circular, with rim 
thickened, giving it a trumpet-shaped appearance; wm- 
bilicus wide and shallow. 
This beautiful little shell is found under stones, 
among moss, and on sand-hills in many parts of Great 
Britain and Ireland. Its peculiarly shaped mouth is 
a sufficiently distinctive mark of its identity. 
The variety is not uncommon. 
At Beaumaris, where it is abundant, I have noticed 
that the type is comparatively rare. 
Var. costata. Marked in line of growth with mem- 
branaceous ribs.
