terminate in a blunt nipple-like point; their inner surface has 7 longitudinal 

 ridges, and they are filled with a pultaceous mass. The width of the 

 duodenum is 5^ twelfths; that of the greater part of the rest of the 

 intestine 6 twelfths; the cloaca, k, is not enlarged. 



The trachea is 6 inches long, rather slender, its breadth at the top 3 

 twelfths, at the lower part 2j twelfths. The rings are feeble and unossified, 

 100 in number. There are no inferior laryngeal muscles. The bronchi are 

 very short, rather wide, of about 12 half rings. The lateral muscles are 

 rather large, the sterno-tracheal slips moderate.
