Young. Differs from the adult in having the whole of the upper 

 surface nearly uniform brown, the mantle mottled with indistinct 

 blackish cross-markings and a few whity-brown streaks ; quills 

 more uniform, with less distinct cross bars ; tail-feathers blackish, 

 with less distinct cross bars, especially on the outer feathers ; under- 

 neath whiter than in the old bird. 



Ohs. Considerable variation is shown in different specimens of 

 this species, some being far more rufous above and more fulveseent 

 below than others : br;t a great deal of this difference is dependent 

 upon age and season, the breeding birds becoming evidently bleached 

 and rendered paler by the abrasion of the feathers. Messrs. Salvin 

 and Godmau have recently united the present species to the C.poJy- 

 glottus of Brazil and Bolivia ; and after examining the specimens in 

 their collection as well as in Dr. Sclater's, I am also inclined to 

 unite the whole Neotropical series as one species ; but at the same 

 time the Bolivian bii'd has a very regularly banded tail, almost as 

 in C. hrunneiceps. I subjoin the description of a Bolivian skin : — 



Adult (Khapaguaia, Bolivia ; C. Buckley). Head dusky brown, 

 distinctly streaked w ith fulvous brown ; the hind neck more uniform 

 brown ; mantle black, very broadly streaked dowia the centre with 

 bufiPy white ; lower back and rump reddish brown, as also the upper 

 tail-coverts ; scapulars and w^ng-coverts fulvous brown, slightly barred 

 with dusky blackish, more distinct on the greater series ; quills 

 dusky brown, chtquered externally with dusky and fulvous, the 

 inner secondaries barred across ; tail-feathers rufous-brown, a little 

 clearer on the edges, all the feathers regularlj' barred across with 

 black, about fourteen bands being plainly discernible ; lores, eyelid, 

 and a narrow eyebrow fulvous brown, as also the cheeks and ear- 

 coverts, which are streaked with dusky brown ; throat and centre 

 of body dull white, the sides of the breast, flanks, thighs, and under 

 tail-coverts fawn-buff ; under wing-coverts and axillaries silkj- white; 

 quiUs dusky brown below, ashy along the edge of the inner web. 

 Total length 3-8 inches, culmen 0-55, wing 1-8, tail 1-75, tarsus 0-7.
