5'J. PITYLUS. 



Type. 



Pitylus, Cm. Regn. An. i. p. 41.3 (1829) P. grossus. 



Cissurus, Reich. Av. Syst. Nat. t. 77 (IBoO) p. fuliginosus. 



Periporpliyriis, Reich. Av. Si/st. t. 77 (1850) P. erytliromelas. 



Caiyothraustes, Reich. Av. Syst. t. 78 (18o0) P. viridis. 



In Pitylus the Tanagrine bill reaches its greatest development, and 

 it is bj no means easy, it must be confessed, to draw the line between 

 these birds and some of the Coccothraustine Finches. But most of 

 the Piii/li show traces of the commissural tooth, and all possess the 

 terminal notch and more or less hooked termination of the mandible, 

 which is characteristic of the Tanar/ridce. 



The Pit)/U, as here treated of, extend over the whole Neotropical 

 area from South Mexico to Paraguay and Bolivia.
