48815, 9, Santiago, Chile): — Above chiefly browuish-black, but this 

 broken by a reddish-fulvous streaking on the head, neck, and back, and 

 by a coarse irregular spotting of the same on the greater wiug-coverts ; 

 all other feathers more or less tipped or margined with the same, liem- 

 iges dusky grayish-brown, with indistinct narrow bars of dusky. Upper 

 tail-coverts immaculate white. Tail dusky grayish-brown, the extreme 

 base pure white, and the tij) fulvous- white, crossed by very numerous 

 (about nineteen) narrow indistinct bars of dusky; their inner webs 

 more whitish, with the bars better defined. Lower parts ochraceous, 

 the throat, jugulnm, breast, sides, and abdomen with longitudinally 

 ovate or tear-shaped spots of brownish-black, largest on the breast. 

 TibiiTi marked with faint, small, and irregular bars of brown. Crissum 

 immaculate white. 



An adult from Guayaquil (No, 54035) has the blackish more continu- 

 ous, but still conspicuously streaked with white on the throat ; the tibise 

 are pale ochraceous, thickly barred with rusty ; the terminal baud of 

 the tail is less than an inch wide, and is tinged with gray. Nos. 13907, 

 female, and 13908, male, from Chile, differ in having the black much, 

 broken, both above and below, but chiefly on the lower surface, with, 

 white spottiugs and streaks ; the throat and cheeks white, streaked 

 with dusky. These two specimens correspond quite closely with Tem- 

 minck's plate of the adult.
