latter being most distinct on those feathers which overhang 
the upper portion of the tarsus ; on the outer sides of the 
thighs the rufous is mingled with transverse bars, not only 
of white, but also of dark and pale grey; the under tail-coverts 
are crossed by alternate bars of rufous and white. 
No. 3, from the same district of New Granada as No. 1, 
resembles No. 2, but exhibits a considerable amount of deep 
rufous on the upper portion of the wing-lining, the rufous 
feathers in that part having blackish shaft-marks of varying 
breadth, and the broadest of these beiug situate below the 
carpal joint. In this specimen the rufous on the thighs does 
not assume the arrangement of transverse bars. 
No. 4, from Venezuela, and marked as a female by the late 
M. Jules Verreaux, resembles No. 2; but the rufous portions 
of the plumage are not so strongly tinged with that colour, 
except on the thighs; the wing-lining also exhibits some 
rufous, but much less than is the case in No. 3. It also dif¬ 
fers from No. 2 in the absence of rufous from the under tail- 
coverts, some of which are barred alternately with white and 
grey, also in having white interspaces between the transverse 
bars on the inner webs of the tertiaries, and in the grey tint 
of the tail being diffused over the central as well as the lateral 
rectrices. 
No. 5, from the river Amazons, hut without any more defi¬ 
nitely known locality, differs from No. 1 in having all the parts 
which in that specimen are of different shades of slaty grey, 
black with only a very slight tinge of slate-colour (though 
the transverse bars on the wings are discernible in two dif¬ 
ferent shades of slaty black), also in having no white trans¬ 
verse bars on the abdomen and thighs (the latter of which 
show in places a very slight tinge of rufous), in the transverse 
bars on the tail, as well as those on the upper and under tail- 
coverts, being broader, darker, and more distinct, and, lastly, 
in the interspaces between the transverse bars on the inner 
webs of the tertiaries being more or less entirely white. 
No. 6, from Brazil, but from what part of that country I 
am unable to say, resembles No. 5, except that the slaty black 
plumage of the breast is slightly tinged with rufous brown,
