Above dark cinereous, more or less olivaceous : wings and tail 

 blackish, wing-coverts and outer secondaries with more or less 

 defined edgings of dirty white : beneath, throat and breast cinereous ; 

 abdomen and under wing-coverts sulphur-yellow : bill dark brown ; 

 feet blackish : whole length 7'0 inches, wing 3'6, tail 34. Female 

 similar. 



Hob. From Veragua throughout South America to Argentine 

 Republic. 



As has been pointed out by Graf von Berlepsch (Ibis, 1883, p. 139), 

 Gmelin's Muscicapa ferox was based primarily on Brisson's Tyrannus 

 cayanensis, which is certainly this species, and not on PI. Enl. 571, 

 fig. 2, as has been generally assumed. I think, therefore, that we 

 cannot well avoid using the specific name "ferox " for this bird.
