Typical locality Fernando Po. 



Differs from maxwelli by its inferior size (shonlder-lieight 

 about 13 inches), and by the brown of the back shading into 

 black on and at each side of the base of the tail, below 

 which there is a sudden change to white on the hips. 

 Foot-glands consisting of a simple tube, not extending so far 

 as the lateral hoofs, and not expanded into a dilatation 

 between the bones in the manner of maxivelli. Horns of 

 males but little larger than those of females. 



The range includes the country south and east of the 

 Niger, extending on the west coast from the Cameruns to 

 Angola, and eastwards to the coast, opposite Zanzibar, 

 Uganda, and B. E. Africa. The following features serve 

 to distinguish four of the local races of the species : — 



A. Black of back extending on to croup. 



a. Under-parts pale slaty brown C. m . melanorheus. 



h. Under-parts darker (dark isabella-brown) C. m. cequatoi'ialis. 



c. Under-parts drab C. m. musculoides. 



B. Black of dorsal area restricted to region imme- 



diately round root of tail Cm. anchietce. 



The fifth race is too imperfectly known to be included 

 in this key.
