meter of the rectum 2^ twelfths, being the same as that of the gut im- 

 mediately before it ; and there is scarcely any distinct cloaca, the width 

 of that part being not more than 4 twelfths. The coeca, 1 inch distant 

 from the extremity, are 3 twelfths long, | twelfth in diameter. 



The trachea is 2 inches 2 twelfths long, rather wide in proportion 

 to the size of the bird, although not more than 1^ twelfth in diameter. 

 The rings are 58 ; the bronchial half rings about 15, The lateral mus- 

 cles are moderate ; the stemo-tracheal extremely slender. There are 

 four pairs of inferior laryngeal muscles, as in all the singing-birds, whe- 

 ther thick-billed or not. 



The digestive organs of this bird are in all respects precisely simi- 

 lar to those of the Finches, Grosbeaks, Buntings, and other allied ge- 

 nera.
