Sp. Ch. — Male. General color a rich dark purplish chestnut ; the top of the head, the chin, and middle of belly, tinged with 

 brown. Crissum dark brown. Fore part of the back lighter, with two or three more or less interrupted ccncentric bars of dark 

 brown. The feathers of rump and tail greenish brown ; the former edged with paler. Wing coverts and outer wcba of 

 some scapulars blue ; others dark velvet green, streaked centrally with yellowish buff. Edges of greater wing coverts white, 

 as are the axillars and middle of wing beneath. Fealhers of flanks uniform chestnut, without bands. Speculum metallic green. 



Female with the top of the head dusky and the wing coverts blue, as in the male ; the speculum duller. The upper parts 

 dark brown, with lighter edges to the feathers. The under parts are brownish yellow, with a strong tinge of purplisii chestnut 

 in the jugulum, the feathers with concealed spots of brown. The only feathers unspotted with brown on the head and neck are 

 in small patches on each side of the base ol the bill, and in the chin between the rami. There is an obscure dusky patch 

 beneath the head. 



Length, 17.80 ; wing, 7.50 ; tarsus, 1.15 ; commissure, 2. 



Ilab. — Rocky mountains to Pacific. Accidental in Louisiana. Spread over most of western South America. 



The female of this species is very similar to that of the common hlue-winged teal. It is, 

 however, rather larger, and the hill decidedly longer. The unspotted whitish of the head is 

 more restricted ; the under surface of the head not pure whitish, but each feather with a 

 brownish spot, producing a dusky patch. There is almost always a decided purplish chestnut 

 tinge in the jugulum. The tertials are more elongated.
