rynx it is noticeable that as a rule it increases to a certain degree simultaneously with the growth of the spec- 

 imens. A smaller specimen has thus smaller nematocysts than a larger specimen, but the proportion between 

 the size of the nematocysts in the tentacles and that of the nematocysts in the actinopharynx is retained, 

 as the following tables clearly show.
