plumage, and the feathers of the head are rather damaged. I prefer 

 to wait for more perfect specimens before deciding on the distinct- 

 ness of the Bolivian bird. 



Young males are brown like the old females, but are rather more 

 ashy, and have the breast aud abdomen whiter, being in this respect 

 like the adult male. The chiu has a blackish spot, strongly obscured 

 by ashy margins to the feathers, followed by a large white throat- 

 spot, arid below this there are indications of a band on the fore neck, 

 obscured by ashy grey. There is no trace of black on the forehead 

 or lores, and the white streak on the cheeks is obscured by ashy 

 tips to the feathers. 



Adult female. Different from the male. General colour above 

 olive-brown: wing-coverts, quills, and tail-feathers dusky-brown, 

 edged with olive-brown like the back ; crown of head, lores, and 

 sides of face like the baek ; eyelid and feathers below the eye dull 

 whitish ; cheeks and under surface of body ochreous brown, washed 

 with olive-yellow, the throat whiter in the centre ; sides of body and 

 flanks somewhat browner, the abdomen yellowish white : thighs 

 brown ; under tail-coverts ochreous white ; under wing-coverts aud 

 axillaries olive-yellowish, the former white at the base ; quills below 

 dusky, ashy along the inner edge. Total length 4'5 inches, culmen 

 04, wing 2-05, tail 1-6, tarsus 055.
