DESCRIPTION OF BREEDS. 



149 



When the oesophagus of a dead bird was inflated, it was seen to be larger 

 than in other breeds, and not so distinctly separated from the crop. The 

 Pouter inflates both its true crop and oesophagus; the Turbit inflates 

 in a much less degree the oesophagus alone. The beak of the Turbit 



is very short, being -28 of an inch shorter than that of the rock-pigeon, 

 proportionally with the size of their bodies ; and in some owls brought 

 by Mr. E. Vernon Harcourt from Tunis, it was even shorter. The beak 

 is vertically thicker, and perhaps a little broader, in proportion to that of 

 the rock-pigeon.
