 «ometimns rather graduated, the fea'hers rather narrow. Wing about equal 

 to the tail, rounded ; 4th quill longest, 1st about equal to the 8th. Toea 

 rather shorter than in Myiodioctes, the middle without its claw nearly two- 

 thirds the tarsus. 



There is a good deal of variation in the size of bill and other 



features, with different species ; but the broad decurved bill, nearly 



even narrow tail with the lateral feather more or less graduated, 



wings equal to the tail and much rounded, the 1st quill equal to the 8th
