tinuous with the mesentery of the rectum at the junction of the 

 small intestine and rectum. The coeca lie parallel to the most 

 caudal portion of the small intestine, to which they are attached 

 by peritoneum. They enter opposite sides of the rectum just 

 behind the ileocolic valve. Where the coeca parallel the trans- 

 verse part of the small intestine the left one lies craniad and 

 ventrad to the intestine. The right coecum lies caudal and 

 dorsal to it. The left coecum thus lies farther forward on the 

 ovary than does the intestine. 



When a laying period is approached the growing yolks on 

 the ovary crowd the viscera caudad. The intestine and coecum 

 are forced backward and downward from the ovary. The 

 mesentery of the intestine, the intestine itself, the peritoneum 

 joining the left coecum of the intestine, and the left coecum 

 itself, form a partition between the ovary and the other vis- 

 cera. This partition is incomplete dorsal to the end of the 

 left coecum and lateral to the anterior end of the rectum. This 

 space is at the caudolateral angle of the ovary and here the 

 mouth of the funnel is spread out facing that organ. It is thus 

 in the position most advantageous to receive the mature yolks.
