results in a general colour something between " olive-brown " 

 and " Chcetura drab," tlierefore very different from the 

 " ferrugineus " and " rostbraun " o£ Peters's description of 

 Jlavivittis. Under surface white, with a faint tinge of buffy 

 on the belly ; the hairs white to their bases ; line of demar- 

 cation on sides not sharply defined. Colour of lateral light 

 stripes practically white or ivory-colour, not " flavidus " or 

 " hell-gelb " as in true Jlavivittis. Dark line below them like 

 the middle back above them. Top of muzzle grizzled ochra- 

 ceous. Crown and nape dark grey, without buffy or fulvous 

 intermixture. Facial lines well defined, alternately dark 

 brown and white. Shoulders ochraceous, the withers between 

 them also more tinged with this colour than the main dorsal 

 area. Ears whitish buffy. Front of fore limbs and top of 

 hands ochraceous ; inner side of limb whitish. Outer side of 

 hips greyish buffy, top of hind feet strong buffy. Tail-hairs 

 ringed with black and pale buffy, their tips broadly buffy, 

 those of the terminal hairs stronger buffy ; middle line of 

 under surface ochraceous. 



Skull apparently as in jlavivittis, though the nasals are 

 considerably broader behind than in Peters's figure. 



Dimensions of the t} r pe (measured in flesh) : — 



Head and body 175 mm. ; tail 175 ; hind foot 40 ; ear 18. 



Skull : greatest length 41 ; condylo-incisive length 37 ; 

 zygomatic breadth 24 ; nasals, length 12*3, posterior breadth 

 7*5 ; upper tooth-series 8. 



Hab. and type as above. 



In his description of P. jlavivittis Peters mentioned two 

 localities for the species — Mossimboa, on the coast, about 11° 

 S., and Cabaceiia, near Mozambique, — the second being 

 almost exactly the present locality. But the differences in 

 colour from his description and figure shown by Mr. Love- 

 ridge's specimen are so material that there are evidently two 

 subspecies of the animal, and it is obvious that the first- 

 named place — Mossimboa — should be taken as the type- 

 locality. 



Judging by a specimen from still further north which has 

 been hitherto taken as P. jlavivittis, the back of that animal 

 is probably a strong fulvous ochraceous, very different from 

 the dark brownish of P.f. mossambicus. 



This specimen is a peculiarly welcome accession to the 

 Museum collections, as P. jlavivittis was one of the only two 

 species which I was not able to allocate to their restricted 

 genera when dividing the African squirrels in 1909 *.
