MAGUS 171 



width of canines, alveolar border, 37.9; length of upper molar series, 

 36.3 ; length of mandible, 97 ; length of lower molar series, 47.3 ; length 

 of upper canines, 29.8. Ex type Dresden Museum. 



The type of this species is the one also figured by Meyer as Maca- 

 cus maurus in the Abhandl. Berich. Konigl. Zool. Anthol.-Ethnol. Mas. 

 Dresden, 1897, p. 1, pi. I, adult. It is a full grown animal but whether 

 it has assumed the pelage of the adult cannot be determined. Meyer 

 decided afterwards it was not maurus, but a new species and renamed 

 it TONKEANus. It is without doubt the same as Papio (Inuus) tonsus 

 Matschie, which is a much younger animal, and has not yet begun to 

 show any white on the hinder parts. 



The skull is that of a fully adult, but not an old animal, rather 

 of one in its prime. It is the only adult specimen from this part of 

 Celebes I have seen. Until we know more about the changes in color 

 the pelage undergoes from youth to maturity, there is no alternative 

 but to leave it under the name given by Dr. Meyer. It may only be 

 a phase of pelage of M. ochreatus, and eventually these two may 

 prove to be the same species.
