A medium-sized pale-coloured species, with short, white, 

 incrassated tail. 



Fur rather short, hairs of back about 4 mm. in length. 



Colour above grey, washed with pale yellowish cinnamon, 

 geueral eflect as in '"^ drab " mixed with " wood-browu," 

 paler than in any other species excepting deserti, fischeri, 

 and smiflii. Flanks greyish washed with yellow. Lateral 

 gland white. Underparts not sharply coutrasted with upper, 

 the cinnamon tint gradually fading on the flanks and passing 

 imperceptibly into the creamy-grey of the ventral surface; 

 hairs of belly grey with creamy-white tips. The yellowish 

 tinge on the under[)arts is possibly due to some secretion 

 from the lateral glands, the areas around which are stained 

 pale lemon-yellow. Backs of hands and feet white. Tail 

 short, very thick and blunt, white above and below ; bristle- 

 hairs long and fairly numerous, but rather inconspicuous. 



Skull smaller than in hindei, with narrower, more parallel- 

 sided, interorbital region ; brain-case rather flatter. Teeth 

 similar in shape but slightly smaller, small upper unicuspids 

 about equal in size, cusp of second rather longer than that 

 of third.

Head and body 78 mm. ; tail 34-; hind foot 13 ; ear 10. 



Skull : condylo-incisive length 23*9 ; greatest breadth 10 ;
