8. Le Vaillant also saw a blaauwbok bull at 

 Amsterdam, where it had been preserved in 

 excellent condition for fifteen years. He tells us 

 that there was little if any variation between the 

 different specimens he saw, thus unconsciously 

 strengthening the claim of H. leiicophceus to rank 

 as a distinct species. 



9. A blaauwbok is still preserved at Stockholm, 

 and is the identical specimen which helped Sunde- 

 vall to prove the essential distinctness of H. 

 leucophaeiis. It would be interesting to know if 

 this example was brought home by either of the 

 famous Swedish travellers — Thunberg and Sparr- 

 man^ but information on this point will probably 

 now be unobtainable. 



10. The blaauwbok cow, on which Herr Kohl 

 based his valuable paper, is still preserved at 

 Vienna : this and the foregoing specimen are 

 specially interesting, on account of the important 

 deductions which have been drawn from them. 

 Some of the measurements of the Vienna example 

 have already been given. 



11. A blaauwbok is still preserved at Upsala. 



12. The blaauwbok bull still in the Museum of 

 the Jardin des Plantes, at Paris, has given rise to 

 a great deal of discussion. Supposed to have 

 originally come from the collection of the Stadt- 

 holder of Holland, it was acquired by the Paris 



1 P>om the Krakeel River district ?
