Funamhulus tristriatus numarnts, subsp. nov. 



A local race of F. tristriatus, slightly smaller in all dimensions. 



Fur as in true tristriatus. General ground colour above a grizzle 

 of black and huff, giving a general effect of yellowish " drab " 

 approaching " Isabella colour," the " saddle " (extending from the 

 shoulders to the rump) darker, a mixture of black and orange, with 

 three longitudinal pale buff" lines, broader and better > marked than 

 in true tristriatus. Face coloured like the back, with a yellow 

 sufiusion, cheeks bufl'. In the summer coat the ground colour of the 

 saddle becomes jet black, and the dorsal stripes tend to become 

 white, while the yellowish suffusion on the face becomes " tawny " 

 and the cheeks more ochraceous. Below dull white except the anal 

 region, which, like the under-side of the tail, is a bright " cinnamon 

 rufous "; above the tail-hairs are black with white tips, arranged so 

 as to indicate a black and white barring of the tail. Feet coloured 

 like the ground colour of the body, but the grizzling much finer. 



Skull rather smaller, but otherwise quite as in true tristriatus.
