and L. marginatus|=L. arborum (B.-Ch.)| during heavy 
rain, a habit which I have not noticed in the north of 
England, though I have often done so in the south of 
England and also on the continent. It is not recorded yet 
for Radnorshire, and a few of the Scotch and Irish counties, 
but further investigation will probably supply the gaps. 
Thrushes devour it with great relish, first breaking the 
shell on a stone. These ‘Thrush Stones’ are well 
known to country people. The bank vole (JZ glareolus), 
and probably other field mice, are very partial to Helzx 
nemoralis and H. aspersa, and the empty shells may be 
found in their ‘runs’ in quantities. These mouse-eaten 
shells are always eaten through the side, the apex of the 
spire and the tip being left entire, and so need not be 
mistaken for those eaten by thrushes, which are always 
broken at the top of the spire. Mr. C. E. Wright, or 
Kettering, counted a6 mouse-eaten shells in one foot of a 
‘run’ ten feet in length which was full of them. Along 
the sandhills on the north coast of Ireland I used to find 
fresh shells empty and apparently broken by rabbits’ teeth, 
in numbers at the entrances to their burrows, but whether 
‘brer rabbit’ or rats were to blame for this I could never 
discover. At any rate some of the lower animals know 
what is good, and I can from experience recommend 
this species and the next as delicacies. ‘They should be 
left in an empty box to ‘scour’ for a couple of days, and 
then boiled and eaten cold with vinegar and pepper
