THE BLAAUWBOK

 few examples in museums were but dwarf or 

 immature roan antelopes. 



It was left for two Continental naturalists 

 Sundevall, of Stockholm, and Kohl, of Vienna 

 to demonstrate conclusively the right of the 

 blaauwbok to rank as a true species. Sundevall, 

 after an examination of a long series of roan ante- 

 lopes, pointed out that the feet of the adult leuco- 

 phceus preserved at Stockholm were smaller than 

 those of quite immature examples of the roan ; and 

 Herr Kohl, in his valuable paper, " Ueber neue 

 und Seltene Antilopen," has drawn up a list of 

 differences between the two. A careful examina- 

 tion of the Leyden blaauwbok the very individual 

 on which Pallas founded the species will amply 

 demonstrate that the leucophceus was clearly recog- 

 nisable by the following characters : 



1. Horns relatively long and slender. 



2. Ears elongated, but without a terminal pencil

3. Mane directed forwards. 



4. Throat hairs not elongated.

 throat, anteorbital brushes, and pied face abund-
