ON THE BANK VOLE. 365 



With regard to NoEFOiiK, when Mr. Southwell, in 1871, 

 prepared a List of the Mammalia of that county (Trans. Norf. 

 Nat. Soc. i. p. 78, and Zool. 1871, p. 2756) he was unable to 

 include the Bank Vole amongst the species found there ; but 

 some years later, when a revised edition of his Catalogue 

 appeared (Trans. Norf. Nat. Soc. iii. 1884), he supplied the 

 omission, for in the meantime (1878) Mr. F. Norgate had obtained 

 several specimens of this Vole at Sparham, and one in the 

 adjoining parish of Bawdeswell (Zool. 1874, p. 4236, and Trans. 

 Norf. Nat. Soc. ii. p. 469), and in a footnote to the second 

 edition of Lubbock's 'Fauna of Norfolk ' (1879, p. 10) Mr. South- 

 well mentions Keswick, Aylsham, and Northrepps as localities in 

 which it had been met with or procured.* 



Li Suffolk, Mr. G. R. Rope has found the Bank Vole to be 

 " far from uncommon " in the neighbourhood of Blaxhall, where 

 he resides; and in ' Science Gossip ' for July, 1886, he has given 

 an interesting account of it from his own observation, both in a 

 state of nature as well as in captivity. From this account we 

 shall have occasion to quote presently when dealing with the 

 observed habits of this little rodent. 



It was in Essex that the Bank Vole was first detected as a 

 British species, and was described by Yarrell under the name 

 riparia from specimens procured at Birchanger, in that county, 

 in the 'Proceedings' of the Zoological Society for 1832, p. 109, 

 as well as in the ' Magazine of Natural History ' (vol. v. p. 599). 

 Much more recently (1882) Dr. Laver, of Colchester, has seen 

 specimens from West Bergholt and Layer de la Haye in the same 

 county (Trans. Essex Field Club, vol. ii. p. 175) ; and in August, 

 1885, as recorded by Mr. E. Rosling (Zool. 1885, p. 433) an 

 albino Bank Vole was taken by him uninjured from a cat at 

 Chelmsford, and forwarded alive to the Zoological Gardens, 

 where it was identified by Mr. Bartlett. 



In Hektfordshike as well as in Berkshire we have the 

 authority of Yarrell for stating that it occurs. 



In Middlesex, also, Yarrell procured specimens which, if we 

 mistake not, were taken by Mr. F. Bond in the neighbourhood of 



* The so-called " curious variety of the Bank Vole," killed near Norwich 

 in the autumn of 1865 (Zool. 1866, p. 152) proved to be an albino Water 

 Vole.
