which is very difficult to distinguish, is of insignificant depth, very 
squat, and covered exteriorly with lichens. 
The breeding-season lasts from September to January. The eggs, 
of which there are three in a clutch, are of a light buff ground 
blotched over with dull blue, on which occur brown and blackish 
spots, the whole markings forming a thickened band extending round 
the egg and just above the centre towards the blunt end.

This species seems to take the place here of the Pitangus bellicosus 
in other parts of the Republic.

This is a familiar bird throughout the Republic ; but the specimens 
obtained in the extreme north had much longer tails than those 
of the metropolitan district. 
The nest is built high up in lofty trees, having four eggs in a 
clutch. The shell is elongated and rather sharply pointed, with a 
white ground, spotted with rich brown, more thickly towards the 
blunt end; in fact pointwards it is almost free.

Tris dark. 
Of this bird I only saw two or three males and one female, 
during my residence in Misiones, and shot them in the forest near 
the Uruguay; but the female was very difficult to distinguish in 
colour from the leaves. A very striking difference in coloration, 
however, obtains between the sexes.
