This large genus, which comprehends all the Hang-nests except 

 Gymnomystax, varies much in the minor points of structure, and is 

 exceedingly difficult to classify satisfactorily. I agree with the 

 authors of the ' History of North-American Birds ' that it is almost 

 impossible to arrange these birds in clearly defined sections, although 

 the three subgenera which they have indicated may be used as a 

 make-shift. 



Range. The same as that of the subfamily.
