Three clutches of eggs, obtained in October and November, 

 are pure white in colour, and measure : axis 0-7-0-8 inch ; 

 diameter 0*55. 



[Male bird very common, female rare and hard to 

 secure. Both incubate, and I fancy the male does most of 

 the work, as it is more often shot on the nest than the female. 

 They must bring out two broods or more, as they are 

 amongst the earliest and latest breeders. The nest is usually 

 built on some low-growing shrub, not more than four feet 

 from the ground ; no particular locality is chosen, any place 

 seems to suit. — TV. F.~\

This individual, which I imagine to be a young bird, is 

 uniform olive-brown above, the primary-coverts and qudls 

 being dark brown with paler edges, the greater coverts also 

 shewing paler margins ; under parts similar in colour, but 

 everywhere streaked with whitish ; under wing-coverts pale 

 grey ; under tail-coverts isabelline grey. Total length 

 5*0 inches, culmen 0*45, wing 2*45, tail 1*85, tarsus 0'75. 



The species is new to the avifauna of Paraguay.
