27-t On a new Species of Monkey. 



the low temperature of those elevated regions. The skull 

 is generally larger than that of a female of P. schistacea. 

 It is broader across the orbits, and the orbits themselves are 

 much larger and the orbital ridges greatly arched ; the 

 rostrum is broader at base, the palate is longer and its roof 

 flatter ; the orbital ridge more prominent, and the depress on 

 of the frontal beneath the ridge much greater, and the brain- 

 cnse is broader. Unfortunately the posterior portion of the 

 skull of P. schhtacea is lacking and a comparison posterior 

 to the pterygoids cannot be made ; the skull of P. lania 

 indicates a larger animal, but it is impossible to say, with the 

 imperfect material known at present, wdiether this is an 

 individual trait or a specific character.

During a late visit to the Antwerp Zoological Gardens I saw 

 this monkey, and recognized at once that it represented a 

 new species, quite utdike any of the genus Cercopithecus 

 known. I tiien stited my opinion to M. L'Hoest, tiie 

 Director, who, in the most generous spirit, requested me to 

 describe it, and I regret very much ihcit, on account of a 

 Cercopithecus Vhoesti existing to-day, I am unable to name 

 this fine species after him ; but I take this opportunity to 

 thank him for the facilities given me to examine the fine 

 series of Primates in the Gardens. 



C. tnsignisj as the description shows, is a beautiful animal.
