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 being 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, but without any more defi- 

 nitely known locality, differs from No. 1 in having all the parts 

 which in that specimen arc of diflerent 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 lufous brown,
