Addendum to pp. 3-4. 



Dr. Wetmore has pointed out to me that Molina apparently named the continen- 

 tal and not the coastal Turkey Vulture in Chile, so it becomes necessary to use his 

 name iota for the form I have renamed meridionalis and to drop the latter name. 

 Therefore iota used for the coastal bird, as suggested by Chubb, must be replaced 

 by falklandica of Sharpe. I also find it desirable to restore septentrionalis for the 

 larger U.S. race which I included with C. aura aura, to unite with the latter my 

 C. aura insularis, and also to distinguish the small Eastern South American red- 

 headed bird, united by Chubb with the yellow-headed bird under the name of 

 ruficollis, which properly belongs to the former. The races therefore stand as 

 below (the corrections being also indicated) : —
