The trachea in the Tufted Duck is fimilar in fome refpe&s to that 

 of the Scaup, in -others to that of the Pochard* The drum-like 

 portion of it refembles the fame part in the laft-named bird, 

 infomuch as fcarcely to be diftinguifhed from it ; but the bony box- 

 like portion of it is elevated, and not otherwife to be diftino-uiihed 

 from that of the Scaup, than in being fmaller. The trachea itfelf 

 is of equal dimensions throughout, though fmaller than either of the 

 foregoing. By attending to thefe particulars it cannot be miftaken 

 for any other, and in courfe will prevent the occafion of giving a 

 reprefentation in order to identify it.
