it should be distinguished from that animal ; but as the 

 Museum contains a specimen (unfortunately quite young) 

 from Nigeria which seems to be intermediate between the 

 two, we prefer for the present to consider it merely as a 

 subspecies. 



Cephalophus Claudi, sp. n. 



A Cephalophus allied to and about the size of nigrifrons^ 

 Gray, from the Gaboon, but much darker and richer in 

 colour. 



Fur as in nigrifrons. General colour above near "burnt- 

 sienna " ; only slightly paler on the haunches and belly. 



Colour-pattern of the head and face as in nigrifrons, but 

 the actual colours darker; a strong suffusion of black on the 

 shoulders : tail for basal third of its length same colour as 

 back ; second third very sparsely covered with long whitish 

 hairs ; terminal third forming a well-furnished black tuft, the 

 extreme tip with tendency to show white. Throat, belly, 

 and inner side of limbs only slightly paler than back ; the 

 belly with a median dark stripe from the chest to the navel. 

 The fore legs " blue " (as in nigrifrons and many others), 

 but the body-colour extending down to the metatarsus, much 

 lower than in nigrifrons. 



Skull: as compared with that of nigrifrons markedly 

 longer in front of the orbit, narrower between the orbits, 

 flatter on the forehead ; teeth markedly broader ; bullae 

 larger. 



Dimensions of the type (taken in the skin) : — 



Head and body 920 mm.; tail 150; hind foot 210; ear 85. 



Skull: greatest length 185; basilar length 170; greatest 

 breadth 77 ; length of rostrum in front of orbit 102 ; length 

 of nasals 75 ; length of frontals 70 ; interorbital breadth 38 ; 

 bullse 27. 



Uah. Bambili, Welle Basin. 



Type. Adult female. Original number 118. Collected 

 by Capt. G. B. Gosling on 15th April, 1906. 



Ceijh'ilophus ruhidus, Thos., from Ruwenzori is, equally 

 with nigrifrons, closely related to the present form. The 

 presence of a white chin-patch .ind the complete absence of 

 the dark mantle, belly-stripe, and colouring above the hock 

 suffice to distinguish it from Claudi. The skull-characters 

 indicated above as separating the present form from nigrifrons 

 differentiate it still more markedly from ruhidus, as is shown 

 bv the following comparative measurements : —
