Fig. 9. Transverse section of the pharynx of Glycypha- 

 gus platygaster, ? , x 150. The plane of the 

 section cuts the pharynx near its posterior 

 end, so as to catch one of the straight occlusor 

 muscles (mop). 



10. Horizontal section of the distal part of the 



right caeca of the ventriculus of Glycyphagus 

 platygaster, ? , X 225. It contains food 

 material at the proximal end, and at the 

 distal end numerous loose cells which have 

 become exhausted and detached after per- 

 forming the office of absorbing and digesting 

 food globules. Some are empty, some con- 

 tain small urinary or excremental granules.

of Glycyphagus platygaster , ? , X 150.
