GENUS WILSONIA. Bonaparte. 



Bill moderate, much broader than high. Upper mandible with its dorsal outline nearly straight, 

 and very indistinctly notched. Bristles long, at the base of the bill. Tarsus with three 

 scutellae beneath, blended above. Second or third quills longest. Tail rounded. 



Obs. This genus, which was first indicated by Bonaparte, and dedicated to the memory of 

 the great pioneer in American ornithology, has since been very improperly given to the world 

 under the new and less appropriate name of Myiodioctes. It comprises a few species 

 detached from the great genus Sylvicola.
