CHERKIE: OKXITHOLOGY OF THE ORINOCO REGION. I75 
Four sets of eggs were taken in 1907, all showing a very consider- 
able amount of variation in the shade of color and the amount and 
size of the markings. 
One set taken at Caicara on the 7th of jMay. contained two fresh 
eggs. In the nest was also one egg of the Venezuelan Cow-bird, 
Molothrus bonariensis vene::uelcnsis. The two eggs of T. episcopus 
nesophilus are ovate in form and measure 21.75 x 16.5 mm. and 22 x 15.75 
mm. respectively. In one the ground color is dirty white with just a 
shade of bluish green rather thickly marked with dots, spots and blotches 
of pale ecru drab, underlying spots and blotches of blackish clove 
brown ; the general ground color of the other tgg is darker, the 
underlying markings are larger, brownish drab in color, forming a 
nearly solid mass of color about the larger end, and the superimposed 
blotches are a dark vandyke brown. The nest taken with this set 
of eggs is similar to that described above, a compactly woven, thick- 
walled cup composed largely of leaf stems and a few dead leaves 
held in place by a small quantit}' of spider webs. The nest lining 
was composed of small pieces and short strips of some soft thin bark 
beneath a few pieces of fine dead grasses. The nest measures : out- 
side, 10 cm. in diameter by 6.5 cm. in depth; inside, 6 cm. in diameter 
by 4 cm. in depth. It is loosely, and it would seem, most insecurely set 
at the intersection of a small twig, with a larger horizontal branch, the 
union forming a V-shaped support for the nest. 
A nest containing one fresh egg was found near the same point 
May 8th. It was placed between the forks of three large limbs which 
sprang from the same point, two branching almost horizontally and 
one rising at an angle of about 45° from the horizontal. The nest 
rested at the base of the angle between the two horizontal limbs 
which concealed it from below, while the third limb extending out 
over the nest concealed it from above. In the same tree with this 
nest, and none more than 3 m. from it were nests of Myiosetetes 
texeiisis columbianiis. Pitangns sulphuratus ruHpennis and Icterus 
xanthornus, all occupied. The single tgg found in this nest is ovate 
and measures 24.5 x 18.5 mm. The ground color is similar to that of 
those last described ; the markings vary from a mars brown to a dark 
Vandyke, and consist of dots and spots thickly spread over the entire 
surface, and especially about the larger end. 
A nest found May loth, also at Caicara, contained two badly incu- 
bated eggs. This nest was about 4.57 m. from the ground in a guamal
