Compared with the series of C. lincata 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; culmen 0*65 ; wing 2'8; 

 tail 1*9; tarsus 1*1. 



[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 itseli'. — //'. F. \
