Young e (No. 84129, Fort Whipple, Arizona, August 22, 1864; E. 

 Cones): Si ilar to the adult female, but more golden green above, the 

 top of the iioad nearly as bright as the back; middle tail feathers 

 chiefly rufoius, but with larger dusky terminal space than in adult male; 

 : eneath as in adult iemale, but chin and throat conspicuously s])otted,

 feathers, of the. adult plumage ; outer primary broader. 



Young female (No. 3G912, Fort Whipple, Arizona, August 22, 1864;

 feathers is confined to the margins of the feathers ; middle tail-feathers 

 almost wholly greeu, only the lateral portions of the extreme base being 

 pale brownish with a rusty tinge; outer primary broader and more 

 curved. 



Adult males vary in regard to the color of the back, which is

 of tb ; tail-feathers, so dilierent from those of S. alleni, is just the same 

 a~ 1 those examples which have the back and rump wholly rufous. In 

 the color of the rutf or gorget there is very little variation, except that 

 when the plumage becomes old the color becomes "tarnished" to a
