PEE FACE 



The second Volume of the Cataloii,ue of Un emulate Mammals 

 deals with the African Antelopes belonging to the Sub- 

 families Bubalinie, Cephalophinre, Oreotragime, Neotraginse, 

 Madoquinse and Eeduncinge, including the Hartebeests, 

 Gnus, Duikers, Klipspringers, Oribis, Dik-diks, Keedbucks, 

 Waterbucks and their allies. It is hoped that the third 

 Volume will contain an account of the remainder of the 

 Antelopes, of which the Gazelles constitute the most 

 numerous section, and that it will also include the Prong- 

 buck, the Giraffes and the Okapi. 



The present volume has been prepared by Mr. E. Lydek- 

 ker, F.E.S., with the assistance of Mr. Gilbert Blaine. It 

 need hardly be pointed out that the acknowledgments con- 

 tained in Volume I. of the help received from the donors of 

 specimens and from those who have contributed in other 

 ways to the growth of the Collection apply with equal 

 force to those who have assisted in obtaining? and determiniD^r 

 the specimens described in the present volume.
