Hah. Fernando Po or adjacent coast. 



This Monkey is easily di.stingiii.shable from C. pietaurista by its 

 greenish cheeks, ^^"ithout 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

Ilab. West Africa : Delta of Niger (Baihie) ; Cameroons 

 (Cj'ossley). 



I have examined the specimens of this species in the British 

 Museum, including the type which is badly figured (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 Mhich there ia a coloured sketch by Smit in the Library. 

 AVe have since recei^'ed other individuals, but have not always 

 distinguished them from the allied species.
