13. SCIURUS GRISEOGENA (Gray). 
GRAY-CHEEKED SQUIRREL. 
Local name: Ardifa.

including the tip, except two, or sometimes only one, ring about 
li mm. wide of dull orange-buff. A few hairs are black throughout.

darker than in the average specimen. Under parts of body and legs, 
orange-rufous; upper surface of forelegs, fore and hind feet, a dull 
hazel or cinnamon-rufous; base of tail above and below colored as the 
back; the tip black. The intermediate portion above varies in indi-

some black intermixed. Outer edge of under surface of tail about
