PREFACE 



In its general treatment of the subject this volume follows the lines of The 

 Deer of All hands ; generic and sub-generic groups, as well as species and 

 sub-species, being, so far as possible, made to have the same relative rank as 

 in the latter. A similar prominent position is also given to the English 

 names of the various animals described. 



Much that appears in the introductory portion of the companion 

 volume has a bearing on the present work. And it has accordingly been 

 deemed unnecessary to repeat either the distinctive characteristics ot the 

 group Pecora, the subdivisions of the Tertiary period, or the names and 

 limits of the geographical regions into which the surface of the globe may 

 be divided ; all these being detailed in Tlie Deer of All Lands. 



One feature of the latter — the numerous photographs of living animals 

 — will be missed in the present volume. But this is unavoidable, as there 

 is no collection in this country of the animals described in the sequel 

 comparable with the one which afforded the illustrations in question. 



While the majority of the plates have been drawn by Mr. J. Smit, a few 

 are from original and, with one exception, hitherto unpublished sketches 

 by Mr. Joseph Wolf For permission to reproduce these the author is
