2. MYIOTHERETES. 



Type. 

 Myiotheretes, Reichenb. Av. Syst. Nat. t. lxvi. (1850) . . M. rufiventris. 



The bird usually taken as the type of Myiotheretes is closely 

 allied to the Tcemopterae, but has longer wings and a rather shorter 

 bill. To this Argentine form may be added two somewhat similar 

 species from the Andes of Peru, Ecuador, and Colombia, although 

 they are not quite identical in structure.
