* Itis with no small degree of hesitation that I venture to retain the Smew 
among the birds of North America. But one specimen has ever been actually 
Known to have been obtained here. This was by Mr. Audubon, in Louisiana, 
and, undoubtedly, was but a chance visitor. Wilson was deceived in supposing 
it “common in New England.” It is utterly unknown here, nor has it ever yet 
been discovered in the Arctic Regions. The conclusion, therefore, seems unavoid- 
able that an individual of this species may very rarely wander from the eastern 
continaat to America, but that it cannot be rightly regarded as one of our birds.
