 vol. ii, p. 391, 1907; LydeTiher, Game Animals of Africa, p. 151,

Typical locality "Welle Valley, Congo State. 



Distingiiished from nigrifrons by the much darker and 

 richer colouring, the general colour being burnt-sienna above, 

 with a strong suffusion of black on the shoulders, and only a 

 little paler below than above, but with a dark median ventral 

 line, body-colour extending below hocks in hind-legs. Skull 

 relatively longer in advance of orbits, narrower between 

 them, and flatter on forehead than in nigrifrons ; cheek-teeth 

 broader ; auditory bullte larger. The following dimensions, 

 in millimetres, show the differences in skull -proportion of 

 this species as compared with both nigrifrons and riibidus : — 



claudi. nigrifronfi. rubidics. 



Length of preorbital portion 102 92 85 



Length of nasals 75 70 60

VIII. CEPHALOPHUS EUBIDUS. 



Cephalophus rubidus, Thomas, Proc. Zool. Sac. 1901, vol. ii, p. 89; 

 Thomas and Wroughton, Ann. Mag. Nat. Hist. ser. 7, vol. xix, 

 p. 386, 1907; LydehJcer, Game Animals of Africa, p. 151, 1908. 



Typical locality Euwenzori, E. Africa. 



Closely allied to nigrifrons and claudi, from both of 

 which it differs by the presence of a white chin-patch, while 

 from the latter it is also distinguished by the absence of a 

 dark area on the shoulders and of a dark ventral stripe, as 

 well as by the dark portion of the hind-legs including the 

 hocks. The skull-characters mentioned under the heading 

 of claudi, together with the table of measurements, serve to 

 distingidsh this species still more markedly from nigrifrons.
