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.~\
