 10 twelfths long, 2 twelfths in width ; the proventriculus 5^ twelfths. 

 The stomach is broadly elliptical, 10 twelfths long, 8| twelfths in breadth ; 

 its lateral muscles very large ; the epithelium thick, with prominent 

 longitudinal rugae. The proventricular glands form a belt 6^ twelfths 

 in breadth. The intestine is 14^ inches long, its width 2 twelfths. 

 Coeca 1 inch 9 twelfths long, their greatest width 1^ twelfth ; their dis- 

 tance from the extremity 1^ inch. The trachea is 2 inches 9 twelfths 

 long, from 2 twelfths to 1^ twelfth in breadth, flattened ; the rings
