Family FRINGILLIDyE. 



10. Geospiza strenua Gould. 



Abingdon Island, two specimens; Charles Island, one specimen. 



The specimen from Charles Islaud is a male (in variegated plumage), 

 and is quite undistinguishable from examples from Abingdon Island. 



I am not satisfied as to the propriety of considering the specimens 

 from Biudloe Islaud referred by Mr. Salvin to this species as really the 

 same form, but believe that they represent a local race, all of the three 

 examples in the U. S. National Museum collection having the bill 

 decidedly broader and relatively shorter, as well as lighter colored. I 

 have not seen specimens from James or Chatham Islands, the original 

 localities. 



*The plumage is in such bad condition, however, that a satisfactorj comparison is 

 impossible.
