 the tongue 3 twelfths long, triangular, pointed and slit. Width of 

 mouth 4 twelfths, ffisophagus 1 inch 8 twelfths, its width from 2 

 twelfths to 1^ twelfth. The stomach is 5 twelfths long, 4| twelfths 

 broad. Its contents, insects. The intestine is 4 inches 10 twelfths 

 long, from 1 twelfth to \ twelfth in width ; the coeca extremely small, 

 I twelfths in length, their distance from the extremity 9 twelfths. 



The trachea is 1 inch 4 twelfths long, about | twelfth in breadth,
