pinkish horn-coloured; iris brown. 
Six eggs, collected on October 8, 1903, are pinky white in 
colour, minutely dotted with a deeper tint, which become 
much more dense and darker in colour at the larger end, 
where it forms a zone. Axis 0’7 inch; diameter 0*55. 
A second clutch, obtained on November 16,1903, is similar 
as regards measurements, but darker in colour, and the 
markings more evenly distributed over the entire surface. 
[Resident and common through the central and southern 
parts of Paraguay. It nests in any suitable place, but 
usually in a hole. A favourite material for lining the nest 
appears to be the scales from the leg of a fowl or the skin of 
a snake. Two broods are hatched during the breeding- 
season, and I am of opinion that on some occasions there 
are three.— W. F.~\
