F. grisea. The white eyebrow is very much broader, especially above the ear- 

 coverts, and prodnced to the sides of the nape ; the shonlder feathers are black, 

 edged with white along the outer web (uniform smolcy-brown in 7'"'. grisea) ; the 

 inner secondaries have likewise distinct white edges (in F. grisea they are scarcely 

 margined with pale brownish). Moreover, the two outermost pairs of rectrices are 

 white for the entire apical half of their outer web, while in F. grisea the penultimate 

 rectrix shows but a limited apical spot of that colour. 



The females of the two species are altogether diiferent. In F. mclanogastra 

 the under surface is light cream-buff (Ridgw. 2\omencl. v. 11), the throat rather 

 paler, sometimes even whitish; the flanks shaded with brownish; the under tail- 

 coverts black with white apical margins (not uniform ochraceous as in F. grisea). 

 Ear-coverts and sides of the neck dull black (cream-buff like the cheeks in 

 F. grisea) ; a very broad superciliary stripe from the nostrils to the sides of the 

 nape pure white ; shoulder feathers and inner secondaries distinctly edged with 

 white along the outer web, etc., etc 



The males of F. melanogastra are smoky-brown on the upper parts, the females 

 more reddish, rather rufescent earthy-brown, both being decidedly darker than the 

 corresponding sexes of F. grisea.

These specimens agree with others from Bahia in size and coloration. As 

 stated elsewhere (cf. JSfov. Zool. xiv. 1907, p. 372), skins from Mattogrosso, 

 Forthern S. Paulo, and Humaytha (on the Rio Madeira) have rather brighter, 

 more ochraceous flanks than those from Bahia and Goyaz.
