14 Mr. P. L. Sclater on the Genus Spermophila. 



Bolivia, Chiquitos et Guarayos (D'Orb.); Mattogrosso {Natt.); 

 S. E. Brazil, Bahia [Wucherer); Paraguay {Mus. Smiths.). 



In my ^ Catalogue ' I followed Bonaparte in keeping S. bou- 

 vronides distinct from the present species, on account of the ab- 

 sence of the vertical stripe. This, however, seems to be an ac- 

 cidental variation^. In one skin from Trinidad before me it is 

 not present; in a second it is only just apparent. In a third from 

 Venezuela it is well developed. A skin in the Smithsonian col- 

 lection, from the Parana (Rio Vermejo), agrees very well with 

 ordinary Cayenne specimens, showing that this species has a 

 wide distribution.
