S6^ Mr. Swainson on several new groups in Ornithology, 



This group is nearly allied to the last, both in structure and 

 economy. The fifst quill feather is unusually broad and entire ; 

 and there is a narrow row of small feathers down the sides of the 

 tatsi. All the species I have seen are from America.
