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

 the true C. 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.
