Compared -with the series of C. lineata from Brazil, in the 
British Museum, the Paraguayan bird is less rufous above and 
more inclined to olive, the rufous of the throat and chest 
is much paler, and the white on the middle of the abdomen 
more extended. The under tail-coverts shew scarcely any 
trace of rufous, which is conspicuous in the Brazilian species. 
I agree, therefore, with Mr. Bertoni. that it is a distinct 
form. Total length 5*3 inches; culrnen 0'65; wing 2*8; 
tail 1*9; tarsus IT. 
[This species is not an uncommon bird in the locality, but 
I have never yet met with a female specimen. I must have 
skinned quite a dozen at one time or another, but not a 
single female among them. It is true that I have generally 
shot them during the winter months, but even then the 
female must have been in the locality. A ground-feeder, it 
can generally be found by the rustling of the dead leaves on 
the ground, in this way locating itself.— W. F.~\
