Hah. Gaboon and Congo {Mus. Lurid.) ; Cabonda {Monteiro). 



The Moustache Monkey is also readily distinguishable by its 

 naked blue nose and yellowish cheek-tufts. It is often brought 

 alive to Europe, and we have had many specimens of it living in 

 the Monkey-house. Schlegel gives Gaboon and Congoland for 

 its localities ; we have received living examples procured by 

 Monteiro in Cabonda, just north of the Congo. 



Sect. B. C'ercoj>itheci cliloronoti. 



The Green Monkeys known to me are six in number. They 

 are all more or less of an olivaceous green above and white 

 beneath. Their arms and legs are greyish, not black. They may 

 be shortly diagnosed as follows : — 



A. Facie carnea 10. cynosurus. 



B. Facie nigi-a. 



a. Frontis fascia alba. 

 a'. Ano concolore. 



f Mystacibus elongatis albis : scroto cseruleo ... 11. griseo-viridis. 



[ Mystacibus modicis ilavidis : scroto viridi ... 12. callitrichus. 

 b'. Ano rufescente. 



/ Dorso olivaceo 13. Mandii. 



\ Dorso flavicanti-olivaoeo 14. pygerythnis. 



b, Frontis fascia alba nulla 15. erythrarchus.

Hab, West Africa : Senegambia ? (Schlegel). 



The Malhrouck is one of the commonest of this genus of Monkeys 

 in captivity. Duriug the past ten years we have had at least 25 

 specimens of it. It is at once recognizable, when aUve, by its pale 

 flesh-coloured face, and the blue scrotum of the male. 



Schlegel beheves that Senegambia is its true patria, but this is 

 a point upon which further information is required. I find it 

 included in Eochebrune's hst (' Eaune de la Senegambie,' Mamm. 

 p. 33), but I fear his authority is hardly reliable.
