The trachea of the male has a bony 
bladder and arch, somewhat in shape like 
that of the Pintail ; but the globular part 
not quite so large : we may observe too, that 
it adheres to the side of the arch, quite to 
the bottom, whereas in the Pintail it is at- 
tached to the side of the arch by a small 
portion only.
