THE BLAAUWBOK 49 



in that region, and has never been recorded south 

 of the Orange River; so that even accepting Sir 

 Andrew's statement, many weary leagues would still 

 intervene between the southernmost limitof the roan 

 and the northernmost limit of the blaauwbok. If the 

 two species were identical, surely fossilized or other 

 remains would have been unearthed by this time 

 in the intervening districts. 



We may conclude this account of the blaauwbok 

 by adding a census which enumerates all recorded 

 specimens ; many of these unfortunately are not 

 known to exist. 



I. Pallas 's type specimen, an adult bull, is still 

 in the Leyden Museum, where I have repeatedly 

 examined and photographed it. It is a fine 

 specimen in excellent preservation, and probably 

 carries the record horns. Measurements were 

 taken by me in 1901 ; it is instructive to compare 

 them with those of the female example at Vienna, 

 by means of the following table : — 



Blaauwbok Bull Blaauwbok Cow 

 (Leyden). (Vienna). 



Length of horns along anterior curve - 24'iin. 2o|in. 



Circumference of horn' at base - - 6|in. 5in. 



Height at withers . . - - 49;|in. 4oiin. 



Tip of muzzle to root of tail - - 73iin. 75 sin. 



Number of rings on each horn - - 35 26 



It will be noticed that the len«-th of the male is 

 less than that of the female ; Herr Kohl, however, 

 does not state whether this measurement in the 

 Vienna specimen was taken from the mtizzle to
