CHERRIE: ORXITHOLOGY OF THE ORIXOCO REGION. 277 
While the characters separating H. c. canadensis and H. c. trinitatis 
are not great, nevertheless they seem to me sufficiently constant for one 
to be justified in recognizing trinitatis as a subspecific form. In a series 
of sixteen females from Trinidad, the Caura River, middle and lower 
Orinoco regions, not one has the crown as light as in two specimens 
from Cayenne. In the Cayenne birds the crown is almost clear russet, 
while in the others the average is nearer a chestnut. The under parts of 
specimens (females) from Trinidad, Caura River and Orinoco delta, 
average decidedly more buft'y, or better perhaps buft'y clay coior, the 
wash of the color extending over the entire under parts including the 
centre of the abdomen. 
Birds from the middle Orinoco, from Ciudad Bolivar, and beyond, 
are intermediate in general color between the Cayenne birds and those 
from Trinidad, the Orinoco delta, and Caura River points, being as a 
series, at once distinguishable by their paler coloring both above and 
below. This pale coloring is perhaps more marked in the females, but is 
ver\^ evident in. the males also when compared as a series. So character- 
istic does this paler form seem of the middle Orinoco region that I 
would designate it as 
HVpolophus can-^densis ixtermedius subsp. nov.i 
The nesting season on the middle Orinoco is evidently a long 
one, as I have found young birds in the nest in June, and fresh eggs in 
September. The nest is a thin walled, rather loosely, though neatly 
woven cup, suspended between the forks of a horizontal twig. Nesting 
sites are similar to those of our Red-eyed Vireo. Two eggs collected 
September 4, 1898, at Santa Barbara (near the mouth of the river 
Carcunaparo, or sometimes called the Sinaruco) were "short ovate in 
form, glossy white, covered with frequent red-brown spots, in color 
and measured 21 x 16 and 20.5 x 16 mm-." 
A male in juvenal plumage, that cannot have been long out of 
the nest, taken at Caicara. June 15, 1907, closely resembles the adult 
female above and below, but there are no mesial blackish streaks on the 
breast. 
Another example, a male in transitional plumage from the juvenal 
stage to that of the adult, is similar below to the adult female, and above 
differs from the adult only in having the crown parti-cnlored. a few
