These specimens are identical with others from South¬ 
east Brazil in the National Collection. I do not, therefore, 
see any reason for upholding Myiarchus stauffenbacherianus 
Bertoni, and have placed it as a synonym of the present 
species, as suggested by Dr. Ihering. 
[This species is resident but rare. It can only be found 
in the large forests of the district : I have never met with 
it elsewhere. Like most of the larger Tyrant-birds of the 
montes, the open tracts are its favourite places, where 
flight is possible after insects without too much care being 
necessary to avoid obstacles.— W. F.~\
