1894.] MAMMALS OF NYASALAND. 143 



c. Yg. sk. INIilanji Plain, 4000 ft. 27/10/91. (P. cat:>ensis 

 ofP.Z. S. 1892, p. 553.) 



" Found among the rocks at base of clifPs." — A. W. 



Allied to P. capensk, and therefore belonging to Procavia in the 

 narrowest sense ; no relationsbip to " Heterohyrax " or '■'■Bendro- 

 Jiyrax.^ " 



• Size large. Fur comparatively harsh, at least in the type, killed 

 in early summer. General colour of body brown grizzled with 

 white, the grizzling far coarser than in P. capemis. Underfur 

 smoky brown. Crown of head deep reddish brown, without white 

 grizzling, much as in some of the red-headed examples of P. ahijs- 

 sinica. Cheeks grizzled grey, blacker just beneath the eye. Ears 

 of medium length, thinly clothed internally with whitish, externally 

 with black hairs. A prominent blotch behind and below the ears 

 deep black, this colour running in the type vertically dovni the 

 sides of the neck. Chin bla<k ; throat and chest grizzled grey ; 

 belly deep dirty yellow. In the younger specimens the throat aiid 

 chest are, like the belly, yellow. Arms and legs like back, but the 

 upper surfaces of the hands and feet are deep black. 



Dorsal spot small, roughly oval, uniform black. 



Skull equalling or even exceeding in size that of P. shoana, of 

 which only three skulls, all in Stage VIII., of those measured in 

 1892, have a greater basal length than the present typical specimen, 

 which is only in Stage VII. Diastema rather short," but longer than 

 in P. ccipensis both above and below. Interparietal sutures per- 

 sistent. Interparietal bone, as seen in specimen c. Stage 11., before 

 its form has been altered by the gronth of the masseter, pentagonal, 

 its longest side the posterior one, which is directly transverse, 

 and nearly double the postero-lateral ones. 



Teeth. Molars and premolars very large and heavy, exceeding 

 those of any other species ; no doubt, however, as in P. caijeiisis, 

 they will prove to be variable in this respect. P^ sub-quadrangular, 

 similar in shape to P^, far larger and stouter than in P. ccqjensis. 

 M^ of type no less than 8-5 ram. in breadth, thus exceeding by 

 0"4 mm. the largest molar (of P. shoana) measured in 1892 ; its 

 height too much reduced by wear to be worth measuring. Lower 

 p^ better developed and apparently more persistent than in P. 

 capensis, its horizontal length in the type 3'3 mm. 



Measurements of the type, in skin, 5 : — 



Head and body 560 mm. ; [hind foot of specimen b, 53 ]. 



Skull (Stage YII.) : basal length 90-5, greatest breadth 53 ; 

 nasals, length (median) 23, breadth posteriorly 22-5 ; interorbital 

 breadth 23, intertemporal breadth 26 [interparietal of specimen c, 

 length 8-5, breadth 9-5] ; palate, length 50 ; diastema, above 11, 

 below 4 ; length of upper molar series 44, of lower molar series 45 ; 

 height of lower jaw 50.

 to Procavia capensis, may be conveniently used for any member of the genus.
