ties, ranges from Southern Brazil northward to Costa Rica, and from the 

 Atlantic coast westward to the eastern base of the great Andean chain. Var. 

 cestuans ranges throughout Brazil, extending westward to Eastern Bolivia and

 extends over the northern states of South America, including Venezuela, New 

 Granada, and probably portions of Ecuador, and thence southward to Eastern 

 Peru. In Costa Rica, it seems to be one of the most abundant of the Sciuri.
