This genus was instituted by Dr. Leach. Brisson included the birds contained in it in the 

 genus Querquedula, which is now applied solely to a genus of fresh-water ducks (Anat'uUc). The 

 depth of the keel to the length of the sternum in this genus is as 1 to 4|. Breadth of the pelvis to 

 its length as 1 to 1|. Length of femur to that of tibia as 1 to 1^. Depth of cranium to its length 

 as 1 to 21. 



Affinity. The disposition to rigidity, and the form of the tail, as well as that of the hill and 

 feet, evidently point out an affinity to the next family ; while the skeleton approaches to that of the 

 genus Mergus, both in possessing an ensiform appendage to the sternum, and in the form of the 

 inferior larynx.
