History of Ireknd,’ vol. iv. pp. IG — 18). I have given a full 
description of these supposed hybrids in the Trans. Korfolk and 
^Norwich Nat. Soc. vol. iii. pp. 419 — 421.] 
36. Mus DECUMAXUS (Pall.). Brown Bat. 
37. Arvicola amphibia. Water Vole. 
The black variety is common in this county. Mr. Lubbock says 
that those of the normal type are considerably the larger, and that he 
has “ never observed a brown and black one together, but that the 
colours always correspond.” An albino Water Vole was killed at 
Castle Acre in September, 1872. 
38. Arvicola agrestis (DoSelys.). Common Field Vole. 
Mr. Lubbock speaks of this species as “ the Mouse of the 
marshes, the staff of life, as it were, of the Weasel and the Kestrel 
Hawk.”* 
39. * Arvicola glareolus (Schreb.). Bed Field Vole, Bank 
Vole. 
I have received several specimens of this animal from various 
localities in Norfolk. It is probably much more frequent than is 
generally supposed. 
Fam. Leporid.e. 
40. Lepus europ.eus (Pall.). Common Hare. 
In addition to the varieties mentioned in my former list, “ a 
beautiful specimen of a Black Hare, captured at Merton, the seat of 
Lord Walsingham,” is recorded in Morris’ ‘ Naturalist,’ vol. viii. 
(1858) p. 97. 
41. Lepus cuniculus (Liv.). Babbit. 
The black or “ silver-grey ” race of Babbits has long been 
established about Thetford and Brandon. In Gage’s ‘ History and 
Antiquities of Hengrave ’ (page 190) occurs the following extract 
from the ‘ Household Book ’ of Thomas Kytson, October, 1573 : — 
“ For baiting my Mr. his horse at Brandon, &c. . . . For vj 
Black Coney skins, to fur my Mres. night gown iiij'. iiij**.” 
* In the second edition of Lubbock’s ‘Fauna of Norfolk’ (p. 10) 1 have 
inadvertently quoted this remark as applied by 3Ir. Lubbock to M. stjlvaticus, 
and avail myself of this, the first opportunity of correcting the error.
