446 THE ZOOLOGIST. 



Antelopes. The matter, however, was rightly settled in favour 

 of the Blaauwbok as a true species. The measurements of 

 several existing specimens were found to coincide ; Sundevall, 

 who examined a long series of Roan Antelope of all ages and 

 both sexes, pointed out that the feet of the Stockholm leucophcea 

 were smaller than those of even quite j'oung equina ; and a long 

 list of differences between the two species has been drawn up. I 

 have myself repeatedly examined the Leyden specimen, which 

 plainly shows that the Blaauwbok was distinguishable by the 

 following characters : — 



1. Horns relatively longer than in the Roan Antelope. 



2. Ears relatively shorter, and not pencilled at the tips. 



3. Mane directed forwards. 



4. Throat-hairs short. 



5. No anteocular switches of hair. ,. 



6. No black on face. 



Compare this with the short stout horns, immense ears, 

 hogged mane, ruffed throat, anteocular brushes, and magpie 

 face of the Roan. The fine bull Blaauwbok in my photograph 

 is surely distinct enough from any of the allied species; for, if 

 merely a small though adult Roan, why is there no black on the 

 face ; if immature, why does it carry such fine curved horns ? 



There is another point, not hitherto, I think, mentioned by 

 zoologists. The geographical distribution of the two species is 

 quite different. H. leucophcea was limited to the province of 

 Swellendam, and finally exterminated in 1800 ; H. equinus was 

 not discovered till Dec. 21st, 1801, near Leetakoo (Kuruman), 

 in Bechuanaland, many weary leagues from "the valley of Soete 

 Melk." Had the Blaauwbok occurred in the intervening district 

 at any time, surely its remains, even if semi-fossilized, would 

 have been unearthed before now. 



I have compiled the following census of all recorded speci- 

 mens, many of which unfortunately cannot now be found : — 



1. Pallas's type-specimen. Obtained previous to 1766. 



2. The Haai'lem specimen. Obtained previously to 1766 ; 

 mentioned by Allamand. 



3. Skin seen by Sparrman near Krakeel River about 1772. 



4. Skin bought at Amsterdam previous to 1781. Described 

 by Pennant.
