8. On the Intestmal Tract of Birds. 
By P. Cuatmers Mircuett, M.A., F.Z.8. 
[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. F. 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 
1 “Versuch einer vergleichenden Anatomie des Verdauungssystemes der 
Vogel,” Jena Zeitschrift, xiii. pp. 92-171; pp. 339-403.—“ On the Taxonomic 
Value of the Intestinal OConvolutions in Birds,” P. Z, S. 1889.—Bronn’s
