The slate-coloured legs and dorsal stripe, together with 

 the thicker horns, serve to distinguish this species from the 

 much larger C. harveyi and C. nigrifrons. 



This range extends along the west coast of Africa, from 

 Gambia to the Niger. 



The two local races are distinguished as follows :— 



a. General colour yellowish rufous or ochery buff ; 



nape, dorsal patch, and feet smoky grey C r. rufilatus. 



h. General colour burnt-sienna; nape, dorsal patch, 



and feet slaty grey C. r. rubidior.
