curve, c e f g, and is then convoluted or coiled in numerous folds. The 
rectum is 5i inches long ; the coeca 11 inches, their greatest diameter 6 
twelfths, for 2 inches at the commencement 2 twelfths, toward the end 21 
twelfths, their extremity rounded. 
The trachea, h, is 74 inches long; its diameter at the upper part 4 twelfths, 
gradually diminishing to 31 twelfths; it then enlarges to 5 twelfths, and 
contracts to 34 twelfths at the commencement of the dilatation of the inferior 
larynx, which is extremely similar to that of the Widgeon, but larger; there 
being an enlargement, i, formed by a number of the lower rings united, and 
to the left side a rounded bony tympanum, j; the greatest transverse 
diameter of this part, from i toy, is 1 inch 1 twelfth. The bronchi, Ick, are

PLATE CCCLXXXIX.— Male and Female. 
This lively and very handsome Duck is abundant during winter at New 
Orleans, where it is much esteemed on account of the juiciness of its flesh, 
and is best known by the name of Zinzin. In the Western Country, and 
in most parts of the Eastern and Middle States, it is called the Bald Pate. 
Early in September it enters the United States by their northern extremi- 
ties, as well as from Texas ; and in both these regions it is now well known 
to breed in nearly equal numbers. Those which retreat south-westward 
remain along the coast and in the interior of the Floridas, as well as all that 
portion of the Gulf of Mexico extending to the mouths of the Mississippi, 
where they remain until the latter part of April, sometimes even until the 
middle of May, as they have but a comparatively short journey to perform 
in order to arrive in Mexico in time to breed. On the coast of the Atlantic 
they keep in the marshes in company with various species of the same 
family, being in a manner indifferent as to their associates. During early 
spring, in Louisiana, they are often seen alighted on extensive plains that 
have very little water on them.
