A. TRIDENS (with 3 teeth) Pulteney. PI. V., f. 7.

This species is widely distributed throughout England, 
but it is only recorded for Glamorganshire in Wales, and 
not at all for Ireland. In Scotland, in South Perthshire, 
the variety *wowletiana is found, but the type has not 
been met with in that kingdom. It is often found in 
considerable numbers in moist shady spots. I have taken 
it in the crevices of the limestone rocks in Derbyshire. 
Var. I. cx) stéllina (Dup.). Transparent white. 
Var. I].  nowletidna (Duf.). Rather larger and thinner, 
a single denticle only on the outer lip. 
Var. IIT. alsenénsrs (St. Simon). Outer lip bearing two 
deeply seated denticles in addition to those described in 
the type. 
M. sinistrorum (Taylor). Reversed. 
Genus.—CocHLicopa Férussac. 
Shell sub-cylindrical, smooth ; columella arcuated forwards at the 
base ; aperture elliptic-oblong, narrow. 
*There is a question whether ’. zoudetiana is not the true type; at any rate it 
is the common form in England.
