Such a division, so far as the cycle of development is concerned, can be followed out completely by anyone possessing the necessary number of frogs at disposal - Dactylosoma ending in Schizogony and Drepanidium ending in Sporogony. However, what has now to be considered is the relationship between these two developmentally distinct forms. As already noted, in the Edible or water frog (Rana Esculenta?) both forms are found; on the other hand, the rock or non-Edible frog rarely shows what is generally recognised as Dactylosoma parasites. In this amphibian, parasites typical of Drepanidium are found in the blood corpuscles, the majority of which are large in size, displacing the Nucleus, and show little variation in their microscopic appearance.
