brownish-colored, vesjctable fibers interspersed with bits of grey 
Hchens. The whole is neat and trim in appearance. The measure- 
ments are : outside diameter at base 9.3 cm. ; height 3.5 cm. ; inside 
diameter 5.7 cm. ; depth 2 cm. The eggs are short ovate, white 
with a faint bufTy tinge marked with a few spots and blotches of 
chestnut brown about the larger end. They measure 21 x 16 mm. 
and 21.25 X 16 mm. The female parent was collected, and dissection 
showed that no more eggs would have been deposited. Two therefore 
constitute a full set.

The nesting season in the middle of the Orinoco region lasts from 
early April until the end of Jtme. The nests built by this species 
are modelled on the same plan as nests of Myiozclctcs as described, 
but are very much larger and the materials employed are much 
coarser. A nest, together with three eggs and the parent birds, 
taken at Caicara, May 3rd, was about 4.57 m. from the ground. It is 
a great, rough, ragged-looking ball of grass and weed stemsi, the 
body of which measures about 30 cm. in di;;meter. There is an elip- 
tical entrance hole on one side, the minor axis of which measures 
about 5 cm. and the major about 9 cm. The dead grass immedi- 
ately about the nest cavity and entrance hole is soft and fine. The 
nest was well out toward the end of a large horizontal limb, pressed 
in between forks that supported it from below and on the sides. The 
three eggs taken with this nest were slightly incubated. There is a 
noticeable variation in size and shape. One egg is ovate, one a short 
ovate and the other intermediate between them. They are a rich 
cream color with seal lirown specks and spots, and a lesser number of 
underlying drab spots, grouped in an irregular zone about the larger 
end. Measurements 26.5x19; 27.5x20.5 and 29.5x20.5 mm.
