 very dissimilar. Dr Sclater describes it as " pale olive-brown ; 

 wings and tail darker ; beneath lighter, tinged with ochraceous ; 

 middle of the belly almost white " (Birds of the Argentine Republic, 

 vol. i. p. 46). 



White-throated Finch (Spermophila albigularis). 



Unlike the male, the female is greyish-brown ; the flight and tail- 

 feathers with darker centres ; the first long primaries white at the 

 base, forming a spot in the closed wing as in the male ; under parts

 white edged with yellow.
