TYRANNID.E. 



Subfamily II. PLATYRHYNCHIN.E. 



The Platyrhynchince are a forest-haunting group of the Tyrannidce, 

 distinguished generally by their broadened bill and thin tarsi, 

 modified to suit their arboreal habits. But in the aberrant members 

 of the subfamily these characters become much weakened, until they 

 pass generally into those of the Elaineince. The species are almost 

 without exception of small size and dull olive and grey colours. 



The PlatyrhynchincB extend over the whole Neotropical Region 

 from Southern Mexico to Patagonia.
