The mandrill is strictly contined to the tropical parts of West Africa; the 

 Gabun district being perhaps its headqnartera 



The Drill {Papio leucophobxis). 



Although described by Frederic Cuvier as far back as the year 1807 as a 

 distinct species, the West African baboon represented in the accompanying figure, 



THE DlilLL (jlj Uat. size). 



and knoAvn as the drill, had for many years previously, in s])ite of a figure given 

 by our countrjnnan, Peiniant, been considered to be merely the young of the 

 mandrill, which had not acquired the characteristic coloration of the face. The 

 acquisition of adult specimens of the drill by our museums and menageries proved, 

 however, the correctness of the English and French naturalists' determination. 

 It is exclusively West African, but its range in latitude appears to be somewhat 

 more extensive than that of the maudiill.
