NEW FORMS OF FINCHES AND TANAGERS FROM 



TROPICAL AMERICA. 



BY W. E. CLYDE TODD. 



In the course of a critical study of the Finches and Tanagers 

 in the collection of the Carnegie Museum a number of appar- 

 ently unnamed forms have been discovered. One new species 

 and eleven new subspecies belonging to these groups are de- 

 scribed in the present paper, which is the ninth of the series to 

 appear in these Proceedings, and is governed by the same rules 

 as were observed in the earlier communications. Acknowledg- 

 ments are due to the authorities of the American Museum of 

 Natural History, the Academy of Natural Sciences of Phila- 

 delphia, the U. S. National Museum, the Bureau of Biological 

 Survey, and the Museum of Comparative Zoology for the loan 

 of material which has been invaluable for comparison.
