88 ME. OLDFIELD THOMAS ON [May 21, 



Peocavia ceawshayi Thos. 



Three specimens from the Kuwenzori region. 



This Dassie does not appear to be distinguishable from the 

 species which I described from Kenya and Koromo, from specimens 

 obtained respectively by Messrs. Mackinder and Crawshay. 



It is evidently a variable species, as Sir H. Johnston's three 

 specimens differ considerably among themselves. 



Peocavia (Dexijeohtk.vx) mabmota, sp. n. 



Nearly allied and very similar externally to the West- African 

 P. dorsalis, but smaller and with some cranial differences. 



Fur long and shaggy, hairs of back 40-50 mm. in length, a few 

 much longer hairs being intermixed. General colour dark fuscous 

 brown, very like that of specimens of P. dorsalis in faded fur. 

 Dorsal area rather darker, sides rather paler, the hairs being here 

 subterminally ringed with dull isabelline. Bases of hairs deep 

 brown on back, whitish brown on sides. Under surface dull brown, 

 but little paler than sides, the hairs tipped with dull buffy ; in the 

 inguinal region they are buffy throughout. Hands and feet 

 uniformly brown. 



Naked part of dorsal gland about 35 mm. long by 12 mm. wide. 

 Hairs surrounding the gland black for their basal and dull white 

 for their terminal halves ; the resulting white line on the back 

 about 3 inches in length. 



Skull, as compared with that of P. dorsalis, more slender in the 

 muzzle, the nasals narrower, and the zygomata more expanded 

 anteriorly, so that their broadest point is opposite the back of the 

 orbit. Postorbital bar complete. Malar bones feebler, their least 

 height (opposite the temporal fossa) about 5 instead of at least 

 7 mm. Temporal crests less developed than in P. dorsalis, and the 

 fossse not running so far back on the skull, terminating 14 mm. 

 from the lambdoid edge. 



Molar teeth smaller and lighter, the breadth of m 1 6*0 as against 

 6-fi-Q'8 in P. dorsalis. 



Dimensions of the type, immature, measured in skin : — Head 

 and body 430 mm. ; hind foot 70. Skull : basal length 85 ; greatest 

 breadth 50'5 ; nasals 24-3xl7'7; interorbital breadth 19-5; 

 distance between temporal fossa; across parietals 22 ; diastema 1G ; 

 length of palate 46 ; length of tooth-row (mp 1 to m-) 31"5.

Tyi>e. Immature female. B.M. No. 1.8.9.42. Collected 

 December 8, 1900. 



" Iris dark hazel." 



This Dassie is no doubt most closely allied to the West-African 

 P. dorsalis, which it appears to represent in Uganda. 



The type is in Stage V. of my table of age-stages \ but the skull 

 is neither so large, so stoutly built, nor so heavily ridged as that of 

 a P. dorsalis in Stage III.
