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 particnlar locality is chosen, any place 
seems to suit.-— TV. N.]

This individual, which I imagine to be a young bird, is 
uniform olive-brown above, the primary-coverts and quills 
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.
