 Oregon. It had been previously given as a bird of that country by 

 Dr. Townsend, but is not in the collection of the Expedition.

A fine specimen of this handsome species is in the collection, but is 

 unfortunately without label, and we have not succeeded in finding it 

 mentioned in the notes or journals of the naturalists of the Expedi- 

 tion. 



This species is well figured in Catesby's Carolina, as above cited, 

 and stated to be an inhabitant of the Bahama Islands, but we have 

 never seen a specimen obtained on the Atlantic coast of America. 

 Mr. Vigors, in the paper above referred to, gives it as a bird of North- 

 western America, and it has subsequently been observed on the coast 

 of California.
