PLATE V. Fig. 9. Cnidoblast with a well-developed nematocyst. The 

 double membranes are present, but are regressing in amount. See figure 8. 



Fig. 10. Cnidocyte (mature cnidoblast) which contains a fully-developed 

 nematocyst (not seen in figure). The double membranes in the cytoplasm 

 are severely reduced in amount and only a few strands are left. G is a Golgi
