Dr. Edward Ruppell, in the work above cited, gives a copious de- 

 scription of the form and covering of the Guereza, accompanied by an 

 excellent figure. As to its habits, he briefly states that it lives in 

 small families, on lofty trees, chiefly in the vicinity of running waters. 

 It is active, lively without being noisy, and is inoffensive in its nature, 

 not committing depredations in plantations, as is the case with most 

 other monkeys. Its food consists of fruits, grains, and insects. In 

 former times the Guereza was hunted for the sake of its fur, which was 

 used as a mark of distinction in the army.

 Ms mission to Abyssinia. 



Dr. E. Riippell states that this Monkey is common in the lower 

 regions of Abyssinia, in Sennar, and Kordofan, from the seashore to 

 an elevation of 4,000 feet. Its name is Tota in Abyssinia, Abellen in 

 Sennar, and also in Egypt, where it is extremely common in a tamed 

 or domestic state. (Ruppell, Neue Wirbelthiere, &c. p. 8.) 



The third sub-family of Simiada, according to Mr. Martin's division 

 (Quadrumana, 361), consists of the genera Cercopithecus, Macacus, and 

 Cynocephalus, as generally admitted by modern systematic zoologists. 

 Mr. Ogilby, in the Natural History of Monkeys, &c. (the Menageries, 

 chapter IX. p. 292), has proposed a modification of this subdivision, 

 and has arranged the Monkeys of this family under the genera Cercopi- 

 thecus, Papio, and Cynocephalus, suppressing the genus Macacus, and 

 uniting the long-tailed Macacs from Africa and from the Indian Archi- 

 pelago, in the same genus, Cercopithecus. Although there are some 

 advantages in tttis modification, it has not been adopted by Mr. Martin 

 or by Mr. Blyth. I refer, on this subject, to the remarks with which
