209 species and 8 well marked varieties in the present list, but 

 several of those entered in the former list as good species, or at 

 least as good species with a query, are here treated as varieties 

 or synonyms of other species. 



If this little work should in any degree draw the attention of 

 some at least of those who are fortunate enough to live in the 

 country districts, to the extraordinary richness and the marvellous 

 forms of mammalian life, of which the land of their birth or their 

 adoption is the home, the author's aspirations will have been 

 amply fulfilled. 



With two of the Orders of the Eutherian Mammals, the CETACEA 

 and the RODENTIA, the want of material and of works of reference, 

 and, more especially among the Muridce, the multiplication of 

 species and the number of species insufficiently described, have 

 made the task exceptionally difficult, and the author, therefore, 

 trusts that any shortcomings in these Orders will be leniently 

 dealt with. 



The work has been compiled from various sources, the chief 

 of which are the British Museum Catalogues of Messrs. Thomas, 

 Dobson, and Gray, the different articles relating to Mammals in 

 the Encyclopedia Britannica, especially that under the heading 

 " MAMMALIA" by Professor Flower; but numerous other works 

 and papers by the same authors, as well as by Owen, Huxley, 

 Mivart, Allen, Scott, Stirling, and others have been consulted 

 and freely drawn from. 



In conclusion, I have to tender my best thanks to many 

 friends, in Zoology chiefly to Dr. Ramsay, and in Paleontology 

 to Mr. R. Etheridge, Junr., for valuable hints received and 

 acted on.
