mach would indicate that the bird is graminivorous. The intestine, 

 fh, which is very long, and of considerable width, its diameter being 

 greater than that of the upper part of the oesophagus, is very regularly 

 and beautifully convoluted, presenting, when the bird is opened in front 

 10 parallel convolutions,/^^ ^y^, inclined from right to left at an angle 

 of about 30°. The duodenum, fg h, passes round the edge of the sto- 

 mach, curves upwards as far as the fore part of the proventriculus, is 

 then doubled on itself, reaches the right lobe of the liver, which has a 

 large elliptical gall-bladder, and forms 32 half curves in all, ending 

 above the stomach in the rectum. The intestine is 11 feet 4 inches 

 long, its average diameter 4^ twelfths. The rectum, Fig. 3, ab, is 5^ 

 inches long, its diameter J inch. The coeca, c d, are 4 inches long ; 

 for ^ inch at the base their diameter is 1 twelfth, immediately after 4 

 twelfths ; they then taper to the extremity, which is obtuse. The 

 cloaca is very large and globular.
