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.~]
