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) :— 
4. 
Cathartes aura aura (Linn.). 
For distribution read ‘‘ E. Mexico, Guatemala, Cozumel I., Cuba, Jamaica, 
Bahamas ’’; in description for wing measurement read “‘ 470-505’; and 
before ‘‘ metallic reflections ’’ add “‘ blue and purple.”
