The southern representative of S. minuta is a very closely 

 allied species, to be distinguished mainly, if not entirely, by the 

 clear plumbeous colour of the upper plumage, and the cinna- 

 momeous tinge of the red below. In the latter character a 

 Bogota skin of S. minuta is somewhat intermediate between the 

 two forms. My pair of S. hypoxantha are Nattererian specimens 

 collected at Curytiba in 1820. The Smithsonian collection 

 contains a female obtained in Paraguay during Capt. Page's ex- 

 pedition.
