rounded at its sides; tarsi shorter.

Inhabits North America. 
This is another bird of. which we have entertained considerable 
doubts as to the propriety of making it intoa species: the above dis- 
tinctions, however, appear through all the specimens we have examined 
to be constant. Itis a curious fact that most of the water ducks* 
(Fuliguline) of North America and Europe should be all distinct, 
while those land ducks (Anating) and the mergansers (Merging) 
should, in a great measure, be identical. We can only attribute it to 
their being endowed with a greater power of wing, and to the former 
(Puliguling) following the sea coast in their migrations, and probably 
* We have never examined the eiders of North America.
