Myiozetetes, Scl. P. Z. 8. 1859, p. 46 M. cayennensis. 



This is a widely prevalent form of Ty ran nine life all through the 

 Neotropical Region, except in Chili and Patagonia. The species are 

 very difficult to discriminate satisfactorily, but I am disposed to 

 allow seven as really separable. 



In structure Myiozetetes is a robust version of Elainea, with a 

 stronger beak and feet, and slightly bristled rictus.
