Xerus dabagala rufifrons, subsp. n. 



S . 94, 102 ; ? . 85. Eusso Nyiro. 



Similar to X. dabayala, but with rufous marking on 

 muzzle extending back on to the head, and general colour 

 of dorsal surface richer. 



Size and general proportions as in X. dabagala. General 

 colour of back bright yellowish red, speckled with black, 

 the yellow tint gradually passing into the pinkish brown of 

 the flanks. Back of head slightly darker than rest of dorsal 

 surface and speckled with bright yellow and orange-red, 

 very different from the greyish- brown head of X dabagala. 

 Muzzle and forehead bright orange-red (tan colour no. 2, 

 ' Repertoire de Couleurs '), the reddish colour spreading on 

 to the top of the head and mixing with the dark area on 

 the back of the head. The orange-rufous tint is much 

 brighter and more vivid than in X. dabagala, where the 

 muzzle is more the colour of the flanks. Sides of muzzle, 

 face, and neck bright orange-yellow (maize-yellow no. 4, 

 ' Repertoire de Couleurs ') , strikingly diff'erent from the 

 white face and neck of X. dabagala. Ocular rings pure 

 white. Flanks pinkish brown, speckled with white and 

 black, the white speckling being due to the light tips and 

 the black to dark roots of the hairs. Ventral surface 

 and tail as in X. dabagala. 



Skull similar to that of .Y. dabagala ; rather broader 

 across the interorbital region.
