If, notwithstanding the still imperfect knowledge especiallj 

 regarding the fauna of certain parts of Belgian Congo, an attenipt 

 shoiild be made to give a review of the geographical distribution 

 of the Diiikers in that country, it would give the following resuit 

 on the base of the notes above. 



In the Ubangi-Uele district in the nortli are found Cephaluphus 

 sylvicultrix, C. Weynsi, C. ftigrifrons Claudi, C. castaneus orien- 

 talis, C. rufilatus rubidior, C. leucogaster and C. melanorrheus 

 œquatorialis . 



The ^ouATORiAL FOREST DISTRICT appears to be inhabited by 

 the same Duikers except C. rufilatus rubidior, which hitherto has 

 not been found there. In the most eastern parts of the forest some 

 of the species show a tendency to become smaller and darker. One 

 of the thus ditferentiated subspecies is C. castaneus Arrhenii, and 

 another in the isolated forest Kabwe at Rutshuru, C. Weynsi 

 rutshuricus. 



Some more Duikers which hâve been described from the Eequa- 

 torial forest are not represented in the Muséum ; not having 

 seen them I hâve not been able to form any idea about their afïi- 

 nities. 



On the STEPPES of the northeastern parts of Haut Uele lives 

 Sylvicapra griiiimia Roosevelti, a member of the Sudan fauna. 



On the EASTERN PLAINS, cast of the big forest, Sylvicapra grim- 

 mia lutea is found, which also is at home in Uganda. 



The Kivu DISTRICT is very little known as yet, but one of the 

 more northern Forest Duikers has developed a separate race there 

 viz. C. nigrifrons kivuensis. 



From the western shores of Tanganyika I do not know but 

 one Duiker, which constitutes a well marked geographical race viz. 

 Sylvicapra grifnmia uvirensis.
