can all have sprang from these Surrey specimens ; and he cites the 
distance to which they have spread, in support of this view ; an 
opinion which Mr. Crowfoot seems to share. 
I cannot ascertain for certain that the Dormouse is found in any 
other part of Norfolk, although, as I have before said, there are 
suitable localities in plenty; and it certainly seems strongly in favour 
of those found in the neighbourhood of Geldestone having sprung 
from Mr. Kenick’s introduced specimens, that the species should be 
restricted to a small area of the south-east corner of the county. I 
should, however, attach great weight to Mr. Crowfoot’s opinion.

Large numbers of this pretty little animal are sometimes killed 
on the removal of corn stacks in winter, oat stacks being their 
favourite hibernating quarters. Mr. Gurney has known forty 
killed from one oat stack. On the 8th January, at Blaxhall 
(Suffolk), Mr. G. T. Pope was present at the removal of a barley 
stack, in which were “ a great number of Harvest Mice, many more 
of this species being found than of M. musculus.'” This is the only 
instance in which Mr. Eope had met with Harvest Mice in a barley 
stack.

Probably extinct in this county. I think it likely that Mas 
alexandrinus is sometimes mistaken for this species. An individual 
of the latter species, which was killed at a wharf in Norwich, was 
shown to me in the flesh in August, 1881. Between March and 
May, 1882, I received from the same locality three Eats, which I 
believe to be hybrids between M. alexandrinus and M. decumanus. 
The first received closely resembled M. alexandrinus in colour and 
texture of fur, and length of upper jaw, but in size aird length of 
tail approached M. decumanus. No. 2 also bore the foreign strain 
strongly marked, but was more like the English Eat in general out- 
line ; the third was even more robust. The two latter appeared in 
all respects identical with Thompson’s Mus Hihernicus {cf. ‘Natural
