hairs on chin hardly of a length to be termed a beard, as my description 

 from the type, and Cuvier's plate testify, and Cuvier in his description 

 in Hist. Mamm., says of the chin hairs, "forment une sorte de barbe," 

 which is more beard like than an actual beard. Specimens in the Berlin 

 Museum from Victoria, near Mundame and also from Boscho, are not 

 separable from the true leucoph^us. Herr Hilzheimer's example 

 may not have been fully adult, the chin hairs not appearing long 

 enough to be even beard like, and as he had no skull of leucoph^us 

 to compare his specimen with, he could not show that it was different 

 in any way from that of Cuvier's species, and the Berlin specimen 

 exhibits no distinctive characters. The hair on the chin and throat of 

 P. LEUCOPH^us, while not particularly short, can hardly be considered 

 as forming a beard. 



Dr. J. A. Allen, (1. c.) has determined that Kerr's Simia {Papio) 

 cinerea is this species. Kerr gave the name to an animal described by 

 Pennant in his History of Quadrupeds, vol. I, p. 176, as follows: 

 "Cinereous B. with a dusky face ; pale brown beard ; body and limbs 

 of a cinereous brown ; crown mottled with yellow." 



Parts of this brief and unsatisfactory description may be applicable 

 to the Drill, and we cannot prove that Dr. Allen was in error in his 

 conclusion, neither can it be proved that he was undoubtedly correct, 

 and therefore in view of the fact that it must ever remain questionable 

 as to what species Kerr's description, (which is mainly a repetition of 

 Pennant's), refers, it seems unwise to displace Cuvier's name, which 

 has been universally employed for over a century, and was bestowed 

 upon a species known and accepted by all Mammalogists, in favor of 

 one whose type is exceedingly doubtful, and which can never be proved 

 to be entitled to a specific recognition. The name leucoph.eus F. 

 Cuv., has therefore been retained for the present species.
