PLATE VII. Fig. 13. Digestive cells with relatively small vacuoles and 

 large dark inclusion bodies, probably lipid. The nuclei of digestive cells and 

 fairly light cytoplasm with mitochondria and some double membranes can 

 also be seen. 



Fig. 14. The surfaces of two digestive cells lining the lumen. The cells 

 contain inclusion bodies. The cell membranes at the junction of the two 

 cells near the lumen are rather dense for a short distance and resemble a 

 terminal bar. Short tortuous process of cytoplasm extend into the lumen.
