THE BLAAUWBOK 47 



authorities, and it was finally declared that the 

 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- 

 phceiis preserved at Stockholm were smalle?- 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 leucophcFiis was clearly recog- 

 nisable by the following characters :— 



1. Horns relatively long and slender. 



2. Ears elongated, but without a terminal pencil 

 of hair. 



3. Mane directed forwards. 



4. Throat hairs not elongated. 



5. No switch of elongated hair on the face. 



6. No black on the face. 



The above list of external characters may be

 shorter horns, great ears, upright mane, bearded 

 throat, anteorbital brushes, and pied face abund-
