The trachea, described by Mr. Audubon, "is five inches 

 long, much flattened, its rings unossified, its diameter at 

 the top two lines and three-quarters, towards the lower part 

 three lines, having scarcely any apperance of dilatation at 

 the part which is so excessively enlarged in the Golden- 

 Eyed Duck, which, in form and habits, is yet very closely 

 allied." 



The specimens from which the figure and descriptions 

 here given were derived, were obligingly lent me for my 

 use in this work by Mr. Joseph Clarke of Saffron Wai den.
