Mr. R. B. Sharpe's Catalogue of Accipitres. 121 



youngest example whicli I have examined, the bases of the 

 wing- and tail-feathers being still enveloped in the nesting- 

 sheaths ; it was obtained by Mr. Buckley at Sarayacu, in 

 Ecuador. The upper surface, as well as the sides of the head 

 and neck, are a very dark lustrous brown, the feathers of the 

 nape showing white bases ; the entire mantle is of a similar 

 hue, but a little less intense ; the lesser and median wing- 

 coverts are narrowly and inconspicuously edged with rufous ; 

 the lower scapulars are crossed by two concealed white bars ; 

 and the inner webs of the quill-feathers of the wing are also 

 barred with white ; the tail, which is dark brown, has a nar- 

 row white tip and two imperfect light and partially white 

 cross bars ; the throat is white, with a central and two lateral 

 stripes of dark brown ; the remainder of the undersurface is 

 tinged with buff, which is darkest and most rufescent on the 

 lower breast, abdomen, flanks, and thighs, less so on the 

 upper breast and under wing-coverts, and least so on the 

 under tail -coverts ; the feathers of the upper breast have 

 narrow and very dark-brown shaft-marks, those of the abdo- 

 men and flanks have rufous-brown shaft-marks, and the latter 

 have two rufous cross bars, of which the lowest is terminal ; 

 the thighs on their outer sides are transversely barred with 

 alternate bands of dark and pale rufous ; the axillaries in this 

 specimen are still undeveloped. 



No. 2. (Collection Salvin and Godman.) A young female 

 obtained in British Guiana by Mr. Whitely on 14th October. 

 Though an older bird than No. 1, and beginning to assume 

 adult plumage on the sides of the upper breast and in the 

 tail, it is evidently an individual of a type of coloration similar 

 to that of No. 1, from which it only differs in the following 

 particulars : — The narrow rufous-brown tips to the feathers of 

 the wing-coverts are more extensively diffused, the tertials 

 and upper tail-coverts are slightly tipped with white, and the 

 tail is crossed with three imperfect white bars besides the 

 white tip ; the black marking on the throat is confined to 

 the mesial stripe, the shaft-marks on the upper breast are 

 rather larger, and the feathers of tlie flanks and sides of the 

 breast, in addition to the rufous shaft- marks, are crossed with
