The grizzled medial line of the belly is not constant, 

 not even in individuals from the same locality: thus I 

 find no reason to separate Sciurus gordoni. Our No 2 is 

 colored almost like Sciurus sladani: it evidently is a not 

 fully dressed individual. There are two upper premolars. 

 Skeleton with 12 or 13 costales , 7 or 6 lumbares ahd 

 24 to 28 caudales (Anderson. 1. c. p. 235).
