a membrane, have a more slender head, narrower feet, longer neck, the 
bill more equal, and not so thick a body; they walk better, and feed on 
aquatic plants and seeds as much as on fish, and other animals. The in- 
flations of their trachea consist of a bony and cartilaginous substance 
which is homogeneous.

The Souchets are very remarkable for a long bill, the upper mandible 
of which, forming the exact half of a perfect cylinder, is widened at the 
end. Its lamelle are so long and delicate that they resemble hairs. 
These birds feed on small worms, which they obtain from the mud on the 
edge of brooks.
