A male and female taken at Ciudad Bolivar, April 14th and April 
8th, respectively, are referable to typical doliatus. Specimens from 
Las Barrancas are also referable to the typical form which ordinarily 
is distinguished at a glance from the common Orinoco form by the 
general darker color, narrower white and broader black bars in the 
male and deeper rufous in the female. However, there are occasional 
specimens from the lower Orinoco and delta regions that are somewhat 
intermediate in character and can be referred to one or the other only 
arbitrarily.

Eye straw yellow ; bill black aliove, plumbeous below; feet plumbeous. 
The white bars on the under parts are very noticeably wider than 
in examples of T. doliatus doliatus. making the under parts generally 
much lighter. A nest containing two young was found June 30. It was 
located in a clump of open timber, very near a much frequented path. 
The nest was placed like that of Vireosylva olivacca between the forks 
near the end of a small branch about one metre from the ground. 
The bowl of the nest was as large as that of an American Robin. 
Grass stems and rootlets were the only materials used. 
A nest without eggs taken at Caicara July 4, 1898, by Mrs. Cherrie, 
was situated in a small sapling that stood in an open glade of the 
forest. This nest was about one metre from the ground suspended 
between the horizontal forks of a slender twig and measured 10 cm. 
outside diameter by 7 cm. inside; 5.5 cm. in depth outside, by 4 cm. 
inside. Fine dry grass and long narrow strips of some soft inner bark 
is employed for the outside while there is an inner lining of horse-hair- 
like vegetable fibres. The whole is so loosely woven that eggs could 
be easily seen through the nest walls. 
A second nest containing two young, taken at Caicara by the writer 
Tune 21, 1907, was in a region covered with dense thickets, having only 
a few large trees scattered here and there. The nest was suspended
