Subfamily I. TITYRINvE. 



The Tityrince have mostly a strong Shrike-like bill, with the tip 

 well incurved over tho lower mandible, typical pycnaspidean tarsi, 

 and the toes but slightly connected. Their plumage is not generally 

 bright, but of blacks and whites and greys and olives, of different 

 hues, the males as a general rule being differently clad from the 

 females. 



The special peculiarity of the Tityrince is the remarkable abnor- 

 mality of the second external primary, which is shown in all the 

 genera of the subfamily, and is quite peculiar to this group. 



a. First primary of adult male of Tityra cayaiia. 

 h. Second primary of ditto. 



(P. Z. S. 1857, p. 69.) 



The area of distribution of the Tityrince is nearly coextensive 

 with that of the family Cotinc/idce. 



As regards the nesting of the Tityrincr, Gosse (Birds Jam. p. 187) 

 seems to be our only authority.
