Family Cercopithecid^. 



1. CoLOBUS occiDENTALis Rochebr. 



d . 145. Mokia, S.E. Ruwenzori. 



2 . 169, 170. ]Mpanga Forest, Fort Portal, 



The second species of Colobits mentioned by Mr. Woosnam was most probably 

 C. ruwenzorii. 



[Colobus Monkeys were very rarely seen on Ruwenzori, but they occasionally 

 ascended as high as 8500 ft., the limit of the forest-zone. Another species of Colohus 

 was numerous in the Mpanga Forest east of Ruwenzori. The Red Colobus was not 

 met with, and must be very rare in the district. — R. B. W.] 



[Colobus ruwenzorii Thos. 



Type obtained by Sir H. H. Johnston. No additional specimens were brought 

 home by the Expedition.] 



[Colobus rufomitratus tephrosceles Elliot. 



Discovered by Sir H. H. Johnston in 1900. From the Rnahara River, 4000 ft.] 



2. Cercocebus albigena johnstoni Lyd. 



6 . 172. ? . 173. Mpanga Forest, Fort Portal. 



In the existing doubt as to the proper allocation of C. aterrimus Oudemans, we follow 

 Mr. Pocock, and use the name G. johnstoni for these specimens. 



[A few of these Monkeys were seen in the Mpanga Forest, but they were not at all 

 common. They were not found on Ruwenzori. — R. B. W.] 



3. Cercopithecus ascanias schmidti Matsch. 

 6 . 171. Mpanga Forest, Fort Portal. 



[Not found on Euwenzori, but plentiful in the Congo and Mpanga Forests. In the 

 Congo Forest it is a common sight to see the small native bows adorned with the red 

 tails of this Monkey, slipped on to the unstrung bow while the skin is green. — R. B. W.] 



4. Cercopithecus dkjs^ti Thos. 

 184. Avakubi, E. Congo Forest. 



A member of the C. camphelli-mona group, but not darkened on the posterior back 

 and hind limbs, and with a very sharply contrasted white belly. 



Upper surface of head and neck olive-grey, the usual light frontal band present but 

 not conspicuous. Back dark grizzled chestnut-brown (nearest to " umber-brown " of
