FARRER: MOLLUSCA OF THE ENGLISH LAKE DISTRICT. 157 
in form and colour. A small and very transparent form 
occurs at Bassenthwaite, and many unusual band varieties 
are met with—the formula 10305 being quite common. 
H. arbustorum L.—Common in hedge-rows with its vars. 
alpestrts, conotdea, flavescens, fusca and minima. An un- 
usually large specimen and another with a white band were 
taken near Ouse Bridge, Bassenthwaite. 
H. cantiana Mont.—This species is not found in the district, 
but some introduced by the writer in August of last year 
have increased to at least double the number, so that as it 
is more than likely they may soon spread into the adjacent 
parts I think it better to mention the fact of their intro- 
duction. 
H. rufescens Penn.—Very common and of the usual high- 
spired northern form. Vars. a/ba and rubens frequent and 
var. albocincta not frequent. 
H. hispida L.—Abundant on nettles and in hedge-rows with 
its vars. /zspidosa, subrufa and subglobosa. A curiously 
scalariform specimen was taken near Ireby. 
H. granulata Alder.—On nettles at Piel Wyke, Bassenthwaite, 
Ambleside and Keswick. Not at all common. 
H. fusca Mont. — This handsome snail is very abundant 
throughout wherever sedgy banks border the swiftly running 
“becks.” During the summer dead shells only can be 
found ; about the beginning of September the young snails 
put in an appearance, and in about six weeks more and up 
to April the adult shell may be found in plenty. The 
favourite food seems to be the wild carrot. 
H.fusca Mont. var. vitrea nov.—Shell pale glassy green, animal 
milky white with the exception of the bands leading from 
the tentacles. This, which may be called the albino form 
of AH. fusca; occurs not uncommonly in the Park Woods, 
Bassenthwaite, with the type. When containing the living 
animal, the shell has a curious chalky appearance.
