The trachea of two indivitkials examined, a male and a fe- 

 male, was in the former 7, in the latter V/g inches long ; its 

 breadth at the upper part ^ |, ^^1 ; its rings 102, 96, the two 

 lower dimidiate. Right bronchus of 22, 18 rings, left of 16, 

 15. The contractor muscles large, as are the sterno-tracheal ; 

 a single pair of inferior laryngeal muscles, going to the mem- 

 brane between the last ring of the trachea and the first bron- 

 chial ring. 



In preparing the digestive organs of an individual of this 

 species, I found that the fluid of the proventricular glands had, 

 after a lapse of about a week, dissolved many of the glands into 

 a pulp, as well as the transverse muscular fibres lying over them, 

 while the rest of the tube in its whole length was perfectly 

 sound.
