454 A SPORTING TRIP THROUGH ABYSSINIA 



development are concerned. Many zoologists will find fault with the 

 nomenclature I employ, but not only do I consider it the only 

 right one, but I also wish, by drawing attention, by the use of 

 trinomials, to the existence or possible existence of well - defined 

 local races in large mammals as well as in small ones, to the fact 

 that there is much work still left to be done among the well-known 

 larger mammals for those who cannot hope to get many such startling 

 novelties to describe as the Okapia johnstoni. I have, therefore, in 

 every case where I thought it might be of use, introduced key-lists 

 of the various races of the given species, described from other parts 

 of Africa. In other cases I have given lists of all the described 

 species of the genus found in Africa, so as to induce sportsmen and 

 others to hunt for them all over that continent, and so enable us to 

 form a correct and final opinion as to the relationship of each of 

 such species. 



Guereza guereza (Riipp.). 



(Native name, " Goraza.") 



Riippell was the first to describe this exceedingly handsome monkey in 

 1S35, and it has since been divided into three races as follows : — 



1. Guereza guereza typica. — Abyssinia. 



2. Guereza guereza occidenialis. — Congo and Unyoro. 



3. Guereza guereza caudata. — East Africa. 



I. Managasha forest. 

 INIr. Powell -Cotton says: "Extremely local; I shot these in the 

 forest of Managasha, from which the wood- supply for Adis Ababa is 

 drawn. I found them in high cotton-trees, whose branches, clothed in 

 white lichen, cast deep shadows ; the colour of the animal corresponding 

 so well with its surroundings, that unless it moved it w-as very hard to make 

 out, even with glasses. It has a peculiar, bird-like call which guides one 

 to the place, but when once it has sighted danger it is silent, and hides 

 itself in some deep shadow, where it will remain motionless for some time. 

 Only in one other place, one march south of Dungoler, did I see or hear 

 of any other colony of them, and here they appeared to be very few."
