80 THE ZOOLOGIST. 
We also hesitate to believe that the Marten, the Seal, and 
the Black Rat have any right to be included in the list of 
existing mammals, to swell which Mr. Miller liberally adds four 
species of Arvicola, one of which is A. arvalis, altogether un- 
known to Britain, while he counts A. rubidus and A. riparia 
as distinct. 
So far as the Birds are concerned the less said the better. 
It is true that Mr. Miller has been assisted by some notes by 
Mr. Cordeaux, which, as would be expected of him, are much to 
the point; but that gentleman, so far as we are aware, has never 
made an especial study of the Fen district (in which he does not 
reside), and naturally would not be supposed to have much to say 
of its avian peculiarities. Anything more meagre than the rest 
of the information which Mr. Miller furnishes cannot well be 
imagined. A three-legged Rook shot in the district and preserved 
in the Wisbech Museum is honoured by one of his notes. In 
another the Turtle Dove is pronounced to be only a very occa- 
sional visitant—but it is needless to dwell upon remarks of this 
kind. To the ornithologist they are of no use, to the general 
reader they are misleading. We had looked in such a work 
as this for a full and detailed account of the remarkable 
history of Savi’s Warbler,—a bird which was only discovered 
to be a British denizen just as its last retreat was being 
destroyed,—but all we find given is its name and a note 
(furnished by Mr. Cordeaux) containing a quotation that we 
certainly cannot complain of, but one that never professed 
to give a history of the species. Of the Fishes the list seems 
better by far, but here Mr. Miller has had the assistance of 
Dr. John Lowe, who has before shown himself to be a competent 
ichthyologist. 
It remains for us to say that the present work weighs four 
pounds six ounces, that it contains, besides the preface, con- 
tents, and so forth, 649 pages of excellent paper, and is sump- 
tuously bound. It has a very fair map, several very respectable 
illustrations—the frontispiece excepted—but a wretched index 
and more misprints than it has been our bad luck to encounter 
for a long time.
