the hand, he found it very difficult to detect it in its home amid 

 the forest-trees at high altitudes, where all the branches are 

 clothed with long grey-beard lichens, with which its fur very 

 closely harmonizes. Mr. H. H. Johnston, in describing Man- 

 dara's soldiers, says: "On their heads were crescents made of 

 ostrich feathers, or caps of the Colohus Monkey-skin. This 

 last-mentioned animal also supplied them with mantles of long 

 black and white fur, and contributed the heavily-plumed tails 

 which these ^aga soldiers fixed on to that portion of their body 

 where tails should rightly appear, if man had not dispensed 

 with such appendages." 



" The ' Polume,' as Dr. Livingstone calls this species, is in 

 Uniamuezi known as the ' Mbega,' and is admired on account 

 of its polished black skin and snowy-white mane. It is a cleanly 

 animal, ever occupied in polishing its beautiful garb, which, 

 according to the Arabs, it tears to pieces when wounded, lest 

 the hunter should profit by it. The ' Mbega ' lives in trees, 

 seldom descending to the ground, and feeds upon fruits and 

 young leaves." {Burton.)

 The members of this genus have thin and elongated bodies, 

 long Umbs, and a very long and slender tail. The head is 

 rounded, and shorter than in the Guenons ; the muzzle short, 

 depressed, and but little prominent. The thumb, although 

 shorter than that digit among the Guenons and Macaques, is 

 present in all the species, and forms a good prehensile finger 

 with a flat nail. The hands and feet are long and narrow, and
