mm. They are a pale vinaceous buff, with two sets of markings, 
one superimposed above the other. The inner markings are a pale 
lavender greyish, the outer set ferruginous. In one of the eggs the 
markings are scattered over the entire surface and consist of irregular 
lines and dashes. In the other egg the markings are grouped chiefly 
about the larger end and consist of irregular dots, spots and blotches.

These birds frequent the more thinly wooded districts or the edges 
of thick forest region during the daytime, resting on the ground among 
the fallen leaves, where their colors blend with that of the dead leaves. 
I have never observed this species perched anywhere except on the 
ground. At night they come out in the open savannas, and are fre- 
quently seen about the doorways of the houses as well as out in the 
country districts. 
About Caicara fresh eggs are found from early in March until the 
end of May. There is no nest built and the two eggs are often deposited 
in the most open, and what would seem dangerous, situations, on the 
bare ground. Two eggs found on the 9th of ^larch were near the edge 
of thick forest bordering the river and almost directly in a path much 
used by cattle, pigs, and other animals. The eggs lay on a spot of 
bare ground about 8 cm. in diameter surrounded on all sides by dead 
leaves. Incubation was far advanced and only one egg was preserved. 
It is a pale vinaceous buff in color marked all over with irregular spots 
and blotches of vinaceous brown; ovate in form and measures 28.5x21 
mm. 
The male parent bird and a set of two fresh eggs were collected 
May 5th. The bird, when flushed, feigned a broken wing to draw my 
attention from the eggs. One of these eggs is elliptical-ovate and the 
other between an elliptical-ovate and an ovate in shape. The mark- 
ings are in two shades of color, those of a dark vinaceous overlying 
others of pale vinaceous brown. They measure 28.5x21.3 and 
28.4 X 20.5 mm.
