repeated. Where additional information is given, it is as much 
condensed as possible, reference being given to sources whence 
fuller information may be obtained. Species new to the list are 
marked with an asterisk (*). The species to be removed from 
the previous list are three in number, the Oared Shrew, the 
Greenland Kight-whale, and the Black Eat. Seven new species 
are added; viz., the Parti-coloured Bat, Lesser Shrew, Grey Seal, 
the Dormouse, Bed Field Vole, Atlantic Eight- whale, and Pilot 
Whale, increasing the total from thirty-seven to fortj’’-one species, 
I have some hesitation in admitting the Dormouse, for reasons 
which will be given ; but as it was, doubtless, at one time 
indigenous to this county, I have decided to give it the benefit 
of the doubt; it is quite possible it may never have wholly 
ceased to exist in some parts of the county. In the list of 
Eeptilia and Amphibia no change has been made. 
Since the publication of my contribution in 1871, tbe list of 
“The Mammalia of Essex,” by Mr. Henry Laver, F.L.S., and that 
of Yorkshire,^' by Mr. W. Denison Eoebuck, F.L.S., — both published 
in 1881, but by the kindness of their respective authors corrected 
for me to the present date, — together with the Catalogue of the 
Mammalia of Northumberland and Durham, by Messrs. Mennell 
and Perkins, published in 1863 — enable me to make a comparison 
between the Mammalian Fauna of Norfolk and those of the 
counties named, thus, notwithstanding the absence of published 
lists for Suffolk and Lincolnshire, fairly representing the distribution 
of the members of this group on the eastern coast of England from 
the Thames to the Tweed. 
In order to facilitate this comparison, I have constructed a table, 
showing the species occurring in each county, side by side with a 
complete list of those found in England. The latter is compiled 
from Bed’s ‘ British Quadrupeds ’ (second edition), and includes 
only the species found in the southern division of the kingdom, 
of these Bell enumerates seventy-three. From these I have 
deducted the Pine Martin, which is now proved not to be a British 
species; the Fallow Deer and Eoe Deer, neither of which exist in a 
truly wild state in England ; the Greenland Eight-whale, which it is 
extremely improbable has ever been met with in our seas ; and the 
* Messrs. Clarke and Roebuck’s ‘ Vertebrate Fauna of Yorkshire.’
