 laterad and goes through the funnel mouth. 



the mesentery and lateral body wall. The anterior prolonga- 

 tion of the funnel lies between the air sac and the body wall 

 lateral to the dorsal line of the band of attachment of the 

 sac. Figure 3 is a diagram of a cross-section caudal to the 

 ovary through the coecum. intestine and mesentery, which wall 

 off the ovary caudad. It shows the coecum lying against the 

 dorsal wall of the sac and connected to the transverse part of 

 the small intestine ; the transverse part of the intestine with its 

 mesentery ; the fusion of this mesentery with the mesentery of 

 the stomach ; and the peritoneal connection of the coecum to 

 the dorsal wall of the gizzard, to which the medial margin of 

 the air sac is here attached. The mouth of the funnel is shown 

 dorsal to the end of the coecum and lateral to the intestine and 

 its mesentery. • 



Figure 4 represents a longitudinal section through the "ova- 

 rian pocket" mediad of the mouth of the funnel. It shows the 

 ovary lying dorsal to the air sac and walled off behind by the 

 coecum and intestine with their attached peritoneum and mesen- 

 tery. Figure 5 represents a similar longitudinal section through 

 the mouth of the funnel. It shows the ovary dorsal to the wall 

 of the sac and the funnel caudal to the ovary and dorsal to the 

 end of the coecum. 



The dotted lines numbered 4 and 5 in figures 2 and 3 repre- 

 sent the planes of the sections shown in figures 4 and 5 re- 

 spectively. The dotted lines numbered 2 and 3 in figures 4 

 and 5 represent the planes of the section shown in figures 2 

 and 3 respectively.
