92 HELICIDA. 
5. C. PARVULA (small). 
This shell differs from C. rugosa “in being smaller and 
quite smooth, with the exception of some very faint trans- 
verse lines, which are only observable with a lens, or of a 
few strie near the mouth.” 
Specimens of this species, which is fairly common 
on the Continent, have been found near Stourbridge. 
C. sétmpa (solid). 
As only a single specimen of this Continental species 
has been found near some nursery gardens at Staple- 
ton, near Bristol, whither it was doubtless brought 
with foreign plants, I think its claim to rank as British 
may be disregarded. Had it, like 7. Maugei, “ bred 
and multiplied,” it might be viewed in a different 
light. 
Genus X.—COCHLICOPA. 
1. C. TRipENS (with three teeth). 
Chrysalis-shaped, semi-transparent, solid, glossy, yellow- 
ish horn-colour, sometimes tinged with red or green; 
whorls seven; spire pointed; mouth narrow, with three 
denticles. 
This shell is only found in England, where it is 
widely distributed, but local. It is gregarious, and 
frequents damp moss in shady spots.
