b. At its anterior end this opens into the much smaller, 

 muscular, tkick-walled stomach (Figs. 178, s, 180 and 

 181, h, i). 



c. At the anterior left corner of the stomach are the 



oesophagus (Figs. 180 and 

 181, c), and intestine 

 (Figs. 180 and 181, w), 

 side by side. 



d. The intestine bends 

 upwards between the two 

 p halves of the spleen (Figs. 

 180 and 181, g), and soon 

 becomes constricted to 

 form the rectum (Fig. 

 181,0).
