From the Katanga district not less than four Duikers are 

 reported. The large C. sylvicidtrix extends even so far, and another 

 Forest Duiker C. nigrifrons has developed a subspecies lusunibi 

 there. A niember of the small « blue » Duikers in Katanga is 

 probabl^y identical with C. nyasœ Defriesi, and the Bush Duiker in 

 the same countr_)' bears great resemblance to Sylvicapra grimniia 

 flavescens. 



The CoNGO-BASiN south of the great curvature of the mighty 

 Congo river, west of Lualaba and north of Kasai rivers, is inhabited 

 by the largest among the Duikers, C. sylvïcii/trix, and also b\ one 

 of the smallest, C. Simpsoni. In the district of Lake Leopold II 

 C. Weynsi has been found and in Aruwimi C. castaneiis dorsalis. 

 Otherwise this wide countrj is little known with regard to this 

 group. 



In LowER Congo Cephaloplius castaneus orientalis and C. nyasœ 

 congicus inhabit the forests, and a Bush Duiker Sylvicapra grim- 

 mia splendidula the open countrj, extending there from Angola.
