* The bird described and figured by Wilson as Hamatopus ostralegus was 
probably H. palliatus. It has never yet been ascertained ae certainty that the 
former was ever seen in this country ; we have therefore followed the example of 
Audubon in omitting it. In his description of the female and young, as well as in 
his whole history of their habits, Wilson undoubtedly had the latter bird in view, 
and we have very little doubt that he was wholly mistaken in supposing H. o3- 
tralegus to be a bird of America.
