The trachea is wide, flattened, membranous, 4 twelfths broad at the upper part, gradually diminishing to 2 twelfths, its rings which are very slender, about 100. The lateral muscles exceedingly thin, but becoming more distinct towards the lower part; the sterno-tracheal slender. Bronchi of moderate length, of about 20 half-rings. RED-BREASTED SNIPE. _SCOLOPAX NOVEBORACENSIS_, GMEL. PLATE CCCXXXV. ADULT IN SUMMER AND WINTER. On our arrival at the mouths of the Mississippi, on the first of April 1837, I observed large flocks of this species on their way eastward. They were still in their winter plumage, and it was pleasing to see in how short a period that garb was changed, as we had opportunities of observing during our progress. At Grande Terre, on the 4th, several having reddish feathers scattered over their lower parts were procured. On the 13th, at Cayo Island, the change of colour was very considerable in some specimens, which I found to be old birds, while the younger were quite grey above, and white beneath. At Derniere Isle on the 16th, several were shot in as fine plumage as that represented in my plate, and few, even of the younger birds, were without some of the markings peculiar to the summer dress. Their numbers were exceedingly great, and continued without diminution until we reached Galveston Bay in Texas, on the 26th of the same month. How far they proceed beyond that place to spend the winter I am unable to say; but their range over North America is known to be very extensive, as they have been found on the Columbia River on the western coast, on the borders of the great northern lakes, and over the whole extent of the Fur Countries, from the time of their appearance in spring until that of their return southward in autumn. Although much more abundant along the coast, and in its vicinity, the Red-breasted Snipe is not uncommon in many parts of the interior, especially in autumn, and I have procured many individuals along the muddy margins of lakes, more than three hundred miles in a direct line from the sea. Its migratory movements are performed with uncommon celerity, as many are observed along the coast of New Jersey early in April, and afterwards on the borders of the arctic sea, in time to rear young, and return to our Eastern and Middle Districts before the end of August.
