74 DENDROCOLAniDJE. 



Subfamily III. PHILYDORIN^. 



In tliis subfamily I place the second division of the non-terrestrial 

 bush-haunting DcndrocoJaptida', distinguished from the Si/naUaxince 

 generally by their longer, stronger bill, and shorter tail, but em- 

 bracing forms of otherwise very varied structure and difficult to 

 limit by common characters. 



The l']iU>jdorina'. are found throughout the Neotropical Hegion 

 from Mexico to Argentina, but do not extend to the Antilles.
