There .seems to be considerable variation in the color of Patagonn 
gigas that is not satisfactorily ascribable to sex or age. The lower 
surface in the present examples ranges from a dull mottled brown to 
an almost uniform chestnut-rufous. 
They feed on the flowers of the giant aloes. Local name, ''Quinde golondrina" — 
the swallow hnniniintr bird. They are occasionally seen in the gardens of Quito.

Agyrtria riridiceps HEiyiE, Journ. f. Orn., 1863, p. 185. 
Seven specimens from Santo Domingo,_west Ecuador, The females 
appear to have the crown and forehead noticeabl}' duller than the 
males, and possess, furthermore, a distinct blackish subterminal bar on 
the tail-feathers. This latter is, however, sometimes indicated in 
the males.

Agyrtria amabilis HARTEnT, Tierreich,,IX, 1900, p. 48. 
Five specimens from near Guayaquil, Ecuador. Careful compar- 
ison with a series from Central America and Colombia fails to reveal 
any essential difference. It seems impossible to find an}- structural 
characters to separate Polyerata from Agyrirui.

The one specimen of this species in the collection was taken by Mr. 
Goodfellow from an Indian necklace at Santo Domingo, Ecuador; but 
the make of the skin strongly suggests the probabilit}^ that it originally 
came from the neighborhood of Bogota, Colombia. The fact that the 
species has never been recorded from Ecuador serves to strengthen 
this opinion. 
Personally we never recognized any of these birds alive, and this single specimen 
I found a Colorado Indian woman wearing on her necklace at Santo Domingo. I 
was told it had been shot in that neighborhood.
