The genus of the Mergansers comprehends those species in which 
the bill, thinner and more cylindrical than that of ‘the Ducks, is 
armed along its edges with small pointed teeth resembling those of 
a saw and directed backwards; the tip of the upper mandible is 
hooked. Their carriage and even plumage are those of Ducks, pro- 
perly so called; but their gizzard is less muscular, and their intes- 
tines and ceca shorter. The inflation of the lower larynx in the males 
is enormous, and partly membranous. They live on lakes ene ponds, 
where they are very destructive to fish. 
Three species are found in France during the winter, whose 
variations of plumage have induced some naturalists to increase 
the number. It is said that they breed in the North among the 
rocks or reeds, and lay a great many eggs.
