274 RHINOSTIGMA 



heavy whiskers fringing it in on each side. The animal has changed in 

 appearance since it was first received, and it cannot be said that it has 

 yet fully acquired its permanent dress, and it seems, that at all events, 

 there is one species of Guenon-like Monkey whose young does not 

 altogether resemble the adult. It is a handsome species, and its 

 peculiar face markings will always cause it to be conspicuous. I saw 

 a second example in the Gardens of the Royal Zoological Society at 

 Antwerp. It was smaller than the one in London, but resembled it 

 closely in color and markings. The exact habitat of the species is not 

 known. Since the above description was taken, the type has died 

 in the Zoological Gardens, in Regent's Park, London. The skull shows 

 it was a young animal, with the molar series not fully developed. The 

 last lower molar on each side was not fully through the gum, but both 

 have a posterior fifth cusp. , This excludes the species from the genus 

 Lasiopyga, while its coloring and peculiar face marking prohibit its 

 reception in Cercocebus, but it seems to occupy an intermediate posi- 

 tion as a link between the species of these genera. A new genus, 

 Rhinostigma, has therefore been created for it.
