luctantly omit it from this list, calling attention to the subject as 
worthy of investigation. 
21. Mus MESsoRius (Shaw). Harvest Mouse. 
Somewhat local, hut not uncommon. Mr. Norgate finds it 
frequent at Sparham, and has taken four or five nests in one day. 
At Gillingham, Mr. Crowfoot has taken its nests in the taU sedges 
by the side of the river Waveney, also in the marram grass on the 
beach at Kissingland, almost within reach of the sea spray. 
Two females brought forth young ones in captivity in the Lynn 
Museum. 
22. Mus SYLVATicus (Linn). Long-tailed Field Mouse. 
23. Mus MU3CULUS (Linn). Common Mouse. 
Both common. 
24. Mus RATTus (Linn). Black Eat. 
Messrs. Paget iu 1834, state “ it still remains here though its 
numbers are gradually decreasing.” Mr. Lubbock, in 1845, says 
it is “still occasionally found in the City of Norwich.” Twenty 
years ago I saw one which was killed in the coal-house at the 
Lynn Subscription Library. It is now extremely rare, if not quite 
extinct, in this County. 
25. Mus DECUMANUS (Pall). Brown Eat. 
Common. Cream-coloured and pied varieties sometimes occur. 
26. Arvicola amphibius (Desmar). Water Vole. 
Common in marshes and low ground. Mr. T. E. Gunn records 
the occurrence of the black variety of the Water Vole at Earlham 
in the summer of 1865 : Zoologist S. S., p. 152. 
27. Arvicola agrestis (Flem). Field Vole. 
Common. Mr. F. Norgate found the nest of this species con- 
taining six young, which were blind and naked, at Sparham, on 
the 27th of March j it consisted of a ball of grass placed in 
a slight depression of the ground. Mr. Gurney saw a vole which 
was taken from a kestrel’s nest at Earlham, and which, upon a 
cursory examination, appeared to him to be Mr. Yarrell’s Bank 
Vole, (A pratensis.) As this species has not been observed in 
Norfolk, he thinks the subject worthy of attention. The Bank 
Vole recorded in the Zoologist for 1865, p. 152, is an albino 
variety of A. amphibius with malformed incisors.
