In the Kingfisher, Fig. 30, the oesophagus is rather wide 
and tapering, the proventriculus moderate ; the stomach very 
large and thin ; the intestine very long and slender, without 
coeca ; the cloaca globular. 
In the Finch, Fig. 31, the (esophagus is of moderate 
width, with a slight crop or dilatation on one side ; the 
proventriculus bulbiform ; the stomach roundish, with its 
muscular coat thick and divided into lateral and inferior 
muscles ; the intestine of moderate length and width ; the 
coeca very small ; the cloaca oblong. 
After opening up a few birds, and inflating the alimen- 
tary canal, the student will readily understand all the terms 
used in the description of these parts.
