These specimens are typical /'. g. grisea, agreeing perfectly with others from 

 Ca)'enne. The scapular feathers are uniform dark earthy brown ; the tertiaries 

 dusky and scarcely edged with paler brown along the outer webs : the superciliaries 

 narrow ; the bill rather strong. The males have a large amount of white on 

 the sides of the breast and abdomen, and greyish white axillaries. In the 

 female and 3'onng male the nnder-parts are deep ochraceons, the lower tail-coverts 

 and axillaries paler, more ochraceous-buff, the cheeks and ear-coverts buff, and 

 there is an obsolete, narrow eyebrow of the same colonr.

Of this very distinct species, Imt a few examples were as yet known to exist. 

 The Vienna Museum possesses a male and a female, the types, collected by Natterer 

 in the vicinity of Goyaz, and according to Sclater and Count Berlepsch (in litt.). 

 Prof. Behn obtained, at the same locality, an adnlt male which was formerly 

 preserved in the Kiel Museum, and is now probably in the Berlin collection. 

 Lately, Prof, von Ihering* has recorded a specimen from Avanhandava, in the 

 northern part of the state of S. Paulo. 



The male sent by Mons. Baer differs from Natterer's type by its stronger bill, 

 and by having a few silky white feathers in the otherwise sooty grey flanks. The 

 females and the young male, on the other hand, are absolutely identical with the 

 female in the Vienna Museum. 



Compared with a large number of males of F. grisea, those of F. melanogastra 

 differ at a glance by their much longer tail and slenderer bill. The whole lower 

 surface is deep black with the exception of a few greyish white feathers on the 

 flanks, while in F. grisea all the sides of the breast and of the abdomen are 

 pure white. The axillaries are deep black in F. melanogastra, greyish white in
