Note. — The great genus A7ias is primarily divided into three subgenera : swans, 

 geese, and ducks; which we have indicated by interior braces ; the swans forming 

 only one subgenus, but the geese and ducks several. The last subgenus, tadoma, 

 is still further subdivided, and made to contain the Muscovy duck, the mallard, the 

 teal, &c. ; but our limits prevent us entering into such minute details.
