is closely allied to C. petaurista, but has no black band round the 

 back of the head. There are two skins, received from Leyden, in 

 the British Museum.

Ilab. Fernando Po or adjacent coast. 



This Monkey is easily distinguishable from O. petaurista by its 

 greenish cheeks, without any white stripe beneath the ears, the 

 bluish skin on the face, the greenish colour of the tail abo\o, and the 

 black hands and feet. We have a fine living specimen (received 

 Feb. 19, 1884) now in the Society's Menagerie.

Rah. "West Africa : Delta of Niger (Baikie) ; Cameroons

I have examined the specimens of this species in the British 

 Museum, including the type which is badly figui'ed (I. s. c). I 

 believe it to be a good species, characterized by its black limbs and 

 rufous rump. 



We had a specimen of this Monkey living in the Gardens in 

 1871, of M'hich there is a coloured sketch by Smit in the Library. 

 We have since received other individuals, but have not always 

 distinguished them from the allied species.

The type of this species (badly figured I. s. c.) is in the British 

 Museum. It has the lower cheeks black, a spot between the eye 

 and ear whitish, and the tail-eud rufous.
