 Type. 



[b. $. Eoromo, Kikuyu Forest, 7S00 ft., 29 Nov., 1899. 

 Collected and presented by Eichard Crawshay. Esq.] 



Size and more essential characters very much as in P. valuta 

 True. Fur soft, close, and thick, the majority of the fine hairs 

 about 30 mm. in length, though the scattered black oues are longer. 

 General colour marbled greyish brown with a slight rufous or 

 isabelline hue. Dorsal hairs slaty grey basally, gradually darkening 

 to black at about three-fourths their length, then into a yellowish 

 or isabelline subterminal band and a fine blackish point ; the 

 scattered longer hairs black from base to tip. Head coarsely 

 grizzled grey, the grizzlings black and white, and therefore forming 

 a true grey, very different to the dorsal colour. Hairs below 

 base of ears dull whitish. Dorsal spot narrow, elongate, shining 

 yellowish white ; the hairs, which are 40-45 mm. in length, 

 yellowish white to their bases. Under surface along middle line, 

 from interramia backwards, fulvous or deep buffy, similar to but 

 rather paler than the colour in P. valida ; but the chin and sides 

 of neck are grey, not buffy, and the sides of the chest, the groins, 

 and the inner sides of the limbs are whitish. Outer sides of limbs 

 and upper surfaces of hands and feet like sides of body, not 

 becoming black terminally. 



Skull very similar to that of P. valida and the other allied species. 



Dimensions of the type, measured in skin: — Head and body 

 4C0 mm.; hind foot 59. 



Skull (stage v.) : basal length 79 ; greatest breadth 49 - 5. 



Skull of Mr. Crawshay's specimen (stage viii.) : basal length 85 ; 

 greatest breadth 50 ; nasals 25 X IS ; intertemporal breadth 26 ; 

 diastema 15 ; length of molar series 33 ; greatest breadth of

Type. Specimen a above. B.M. No. 0.2.1.41. 



This distinct species may be readily differentiated from the 

 Kilima-njaro P. valida by its paler and more mottled colour, 

 greyish head, white dorsal spot, the white inner sides of the 

 limbs, and different general colour. The two East African species 

 described by Dr. Matschie, P. stuhlmanni and P. scheelei, both have 

 wholly white bellies. 



Just as the present collection was being examined the second 

 specimen above mentioned (b) arrived from that generous contri- 

 butor to our National Museum, Mr. Eichard Crawshay, and I 

 have therefore dedicated the species to bim, Mr. Mackincler 

 having already a member of the genus named in his honour.
