3. On the Intestinal Tract of Birds. 

 By P. Chalmers Mitchell, M.A., F.Z.S. 



[Received December 13, 1895.] 



The material upon which this paper is based consists almost 

 entirely of birds which have died in the Society's Gardens. The 

 work has been done in the Prosector's laboratory. I have there- 

 fore to express my great indebtedness to the Society and to its 

 Prosector, Mr. P. E. Beddard, F.R.S. 



By his prolonged and beautiful investigations into the structure 

 and disposition of the alimentary canal in birds, Dr. Gadow* has 

 not only proved the taxonomic value of the intestinal convolutions 

 in birds, but has described the details of structure in a very large 

 number of cases. Dr. Gadow paid particular attention to the 

 number of loops and to their disposition in the abdominal cavity. 

 His descriptions and figures refer chiefly to the intestines as they 

 are seen from the right side of the bird's body when the right 

 abdominal wall has been removed. The descriptions and figures 

 now to follow are based on the method described in my paper

 Vogel," Jena Zeitsehrift, xiii. pp. 92-171 ; pp. 339-403.— " On the Taxonomio 

 Vnlue of the Intestinal Oonvolutions iu Birds," P. Z. S. 1889. — Bronn's
