FARRER: MOLLUSCA OF THE ENGLISH LAKE DISTRICT. 155 
during the summer, although dead shells are abundant 
enough. 
Hyalinia draparnaldi (Beck).—A few specimens from the 
base of a garden wall at Keswick, in company with the next 
two species. 
. alliaria (Miller).—Everywhere abundant. 
cellaria (Miull.).—As common as the above, but keeps 
more to gardens and the open country. 
nitidula (Drap.).—Common in woods and on moss-covered 
rocks. Small and rather light coloured. _ 
radiatula (Alder).—Not common, but is found throughout 
amongst dead leaves and moss, also at the roots of the 
bracken fern. 
pura (Alder).—The brown form is common enough through- 
out the district. What is known as var. margaritacea 
occurs only sparingly, so far as I have noticed. I have 
found it only at Bassenthwaite. 
crystallina (Miill.).—Very common and at times very fine. 
. fulva (Miull.).—Abounds in woods and on the borders of 
the lakes amongst dead reeds and under drift wood. The 
var. A/deri (Gray) occurs in moss at Little Tarn, near 
Bassenthwaite. 
nitida (Miill.)—Common on dead reeds and other rejecta- 
menta of the numerous lakes and mountain tarns. 
excavata (Bean).—The var. v¢77na is common throughout, 
but I have not met with the type in any single instance. 
Helix rotundata Miill.—Very abundant. It is a noticeable 
fact that those specimens found in the woods are more 
highly coloured than those taken amongst stones in the open. 
The pretty var. a/ba could be taken in quantity amongst 
some stones on aroad side at Bassenthwaite during the 
whole of last season. ‘This season I have, so far, searched 
for it in vain—the type shell having taken its place. The 
vars. Zurtont and rufula ave also found, the former being 
not uncommon.
