(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; difl'erenoe be- 

 tween 1st and 4th quills, .28 j 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 uropygialis (from 

 Brazil) appeared. It seems, however, to me to agree better with 

 the description of the latter species. According to Sclater the 

 difference of uropygialis 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 the above. Dr. Solater, P. Z. S. 1864, 167, states that B. 

 uropygialis was erroneously assigned to Brazil, and that its true patria is 

 Panama.
