never found in company with H. ericetorum. This 
observation is not of general application. 
The shell of the ‘“‘zoned snail” is conical; white, 
or cream-colour ; with a single dark-brown band 
in the middle of the iast whorl, and with many 
smaller ones beneath. It varies much in colour 
and external markings. A pretty variety has 
two narrow brown bands on the under surface, 
between which is a row of brown spots, eaeh

aperture of the shell, and at a distance of two 
lines from its reflected margin, is a narrow but 
well-marked ridge, usually corresponding to that 
of the mouth, which is a purplish-brown. 
The whorls are six in number, and the shell 
has an average diameter of a fourth of an inch. 
A few specimens collected by me in corn-fields 
on the chalk downs, near Eastbourne, have a 
breadth of seven-tenths of aninch. Mr. J. G. 
Jeffreys has seen specimens from Weymouth a 
tenth of an inch broader. 
Hewix caperata—(the Wrinkled Snail) (PI. 
VIIL., fig. 78).—So called from the numerous con-

further to be distinguished from H. virgata by 
its depressed spire and larger umbilicus, and is 
usually of a much smaller size. The colour of 
the shell is usually of a dull yellowish-white, 
with narrow brown bands. The spire is tipped
