to that species. All have a slight stain of orange in the end of the 
yellow feathers of the crown, not quite so decided as in 26,377.

Hab. Isthmus of Panama. 
(No. 124, Cab. G. N. L.) Upper parts brownish-olive, the head above slightly 
tinged with cinereous ; rump, upper tail coverts, and rather more than basal 
half of tail, with the under parts, yellowish-fulvous, the latter, however, paler, 
and quite light on middle of belly, but darker on the crissum. The sides of 
head, neck and body, inside of wings and breast, washed with olive brown. 
A line from bill to eye, and eyelids fulvous ; lores, and spot behind eye dusky. 
Terminal half of tail brownish-olive, becoming darker to tip. Bill black. 
Legs flesh color. First quill equal to the 8th ; the wings longer than the tail, 
which is rounded. 
Total length, 4.70; wing, 2.30; tail, 2.10; graduation, .30; difference be- 
tween Ist and 4th quills, .28; length of bill from forehead, .62, from nostril, 
36; along gape, .55; tarsus, .87; middle toe and claw, .66. 
This species was identified by Mr. Lawrence as semicervinus 
(from Ecuador) before Sclater’s description of wropygialis (from 
Brazil) appeared. It seems, however, to me to agree better with 
the description of the latter species. According to Sclater, the 
difference of wropygialis from semicervinus consists in having the 
uropygium and under parts lighter, the back olive, and the head 
cinereous, almost as in B. stragulatus, with which also it agrees in 
coloration of lower surface.? 
The species is related to B. stragulatus, although the bill is broader 
' Since writing fie above, Dr. Sclater, P. Z. 8. 1864, 167, states that B. 
uropygialis was erroneously assigned to Brazil, and that its true patria is 
Panama.
