new African Mammals. 199 



Although I provisionally include this distinct mountain 

 form as a subspecies of C. gambianus, it is possible that it is 

 rather a representative of the Angolan C. ansorgei, and that 

 the dark-bellied forms may be related inter si, and distinct 

 from those with white bellies. 



Procavia daemon, sp. n. 



A Dassie of the large-toothed group, allied to P. jacksoni, 

 Thos., but with heavier teeth and more buffy colour. 



Size about as in P. jacksoni. Fur long, rather softer than 

 in typical jacksoni ; hairs of back about 30 mm. in length. 

 General colour <f raw umber," darker and richer than in 

 jacksoni, the subterminal rings on the hairs deep buffy. 

 Underf ur of anterior back brown proximally, dull pale buffy 

 towards the end ; of. posterior back blackish brown, darker 

 terminally than at base. Under surface usually richly 

 coloured, between tawny ochraceous and clay-colour, the hairs 

 paler, more buffy, at their bases. Crown grizzled blackish. 

 Cheeks mixed buffy and blackish, a blackish patch below and 

 behind each eye. Sides of neck dull cinnamon, succeeded on 

 the shoulders by a more blackish tone. Hairs of dorsal spot 

 strong buffy, becoming more ochraceous terminally. 



Skull, as compared with that of P. jacksoni, broader and 

 heavier, the nasals conspicuously broader posteriorly, the 

 brain-case lighter (height from basilar suture to crown, in 

 dcemon 35, in jacksoni 30-32 mm.); basilar region ridged, 

 the ridge on the anterior part of the unusually narrow basi- 

 occipital sharp-edged. 



Teeth markedly larger throughout. 



Dimensions of the type (measured in flesh) : — 



Head and body 445 mm. ; hind foot 71 ; ear 33. 



Skull: basal length 81 ; condylo-basal length 91 ; greatest 

 breadth 49 ; nasals 24*5 X 22; palatal length 46; diastema 

 12 ; front of p l to back of m 2 35, breadth of m* 8*2.

 Original number 359. Collected 11th October, 1909, by

Procavia brucei princeps, subsp. n. 



Size large, largest of the brucei group. Fur comparatively 

 coarse and harsh ; hairs of back about 22 mm. in length.
