1. List of Birds from the Falkland Islands, with De- 

 scriptions of the Eggs of some of the Species, from 

 specimens collected principally by Captain C. C. 

 Abbott, of the Falkland Islands Detachment. By 

 John Gould, Esq., F.R.S., etc. 



Cathartes aura. Turkey Buzzard. 



Captain Abbott mentions the Turkey Buzzard as inhabiting the 

 Falkland Islands ; and on reference to Mr. Darwin's ' Zoology of the 

 Voyage of the Beagle,' I find that the bird which he states is the Ca- 

 thartes aura had also been noticed there by him ; but as much inter- 

 est attaches to this group of birds, particularly as regards the range 

 of the species, it is desirable that Mr. Darwin's opinion of its being 

 the true O. aura should be confirmed or refuted by the receipt of 

 more examples. 



The egg of the Falkland Islands bird procured by Captain Abbott 

 is of a light stone-colour, sparingly blotched and streaked with red- 

 dish-brown, some of the blotches being larger and more distinct than 

 others. Length nearly 2 inches, by an inch and a half in breadth.
