250 BLACK-NECKED STILT. 
The median ridge of the anterior part of the roof of the mouth is 
furnished with a few short papilla. The tongue is 1 inch 2 twelfths 
long, slender, tapering, emarginate and papillate at the base. The 
esophagus is 7 inches long, with an average diameter of 4 twelfths ; 
the proventriculus 9 twelfths long, and 6 twelfths in diameter. The 
stomach is elliptical, 1 inch in length, 83 twelfths in breadth; its la- 
teral muscles of moderate strength, the right being 4 twelfths thick; 
the inner coat or epithelium dense, longitudinally rugous, and of a 
brownish-red colour. The intestine is 20 inches long, its diameter 
varying from 3 to 13 twelfths. The ceca are 12 inch long, 72 im dia- 
meter at the base, 2 twelfths towards the end, which is blunt. 
The trachea is 54 inches long, rather wide, its diameter at the up- 
per part 3 twelfths, gradually diminishing to 1} twelfth; the rings 
120, unossified, excepting a few at the lower part. The contractor 
muscles are feeble ; the sterno-tracheal slender. The bronchi are very 
short, with about 10 half rings. 
The Prince of Mustenano has introduced into his lately published 
list a species of this genus, under the name of Himantopus Meaicanus. 
I have received from Florida two skins, which from their large size 
might at first sight be thought to differ from the common kind; but 
after closely comparing them with my other specimens, I can find no 
difference indicative of a distinction of species. Nor have I ever met 
with individuals in North America of any other species than that above 
described.
