150 PINTADO. 



manner, as to merit description. The construction of the windpipe 

 had nothing singular, but the circumstance, and situation of it, in its 

 passage to the lungs, differs from any other yet noticed ; it passes on 

 the fore part of the neck in the common course, and instead of 

 entering the chest, is greatly elongated, and continues down between 

 the divarication of the clavicle, to the bottom, which finishes in a 

 kind of pouch, compressed on the sides, and about three quarters of 

 an inch in depth, into which it is received ; and bending again 

 upwards, passes into the cavity of the chest, somewhat in the manner 

 of the Wild Swan, but differing, in that the keel in this Pintado is 

 narrow, without any cavity, as in the Swan ; and the bend of the 

 trachea in its case stands about half an inch from it, but attached 

 thereto by a membrane. 



We have been for some time uncertain to what precise Species 

 this curious construction above mentioned belonged, it being merely 

 called the African Guinea Bird ; appearing, however, to have no 

 relation to the first, with which it has been by some compared. 

 This doubt has been cleared up to me by the ingenious and indefa- 

 tigable Mr. Cliff, of the College of Surgeons, who shewed me the 

 bird, from which a breast bone and trachea were taken, precisely 

 similar in structure, and was no other than the Crested Species.
