FIG. 23. Taenia serrata. The figures in succession show the head, or scolex, 

 with suckers and hooks. Enlarged views of the two kinds of hooks are 

 given at the side. The middle figure is of a proglottis constructed from 

 several proglottides of the anterior of the worm, showing the relationship 

 of the generative apparatus. The lower figure is a terminal segment 

 showing the expanded condition of the part of the oviduct termed the 

 uterus, which contains a large number of eggs.
