twelfths in breadth, and its glands are of a cylindrical form, about 2 

 twelfths long, with wide apertures. The length of the intestine is 3 feet 



9 inches. 



The trachea is 9i inches long, of the nearly uniform breadth of 

 4 twelfths ; the rings 132, broad, but very thin and unossified. The 

 bronchi are very short, of about 15 half rings. The lateral muscles are 

 thin ; the sterno-tracheal slips slender. There are no inferior laryn- 

 geal muscles. 



The sternum approaches in form to that of the Herons, the ridge is 

 very prominent, with its outlme rounded ; but the body differs in having 

 two very distinct deep notches on each side posteriorly. 



On the whole, the most direct afl&nity of this bird is to the Spoon- 

 bill ; then to the Oyster-catcher ; in a less degree to the Herons, and 

 still less to the Curlews.
