The histologic observations carried out in the ovary of the pink shrimp reveal, during the sexual cycle, which presents phases that may be identified also by the anatomical examination, three cell types beyond the follicle-cells. All the cells of the proliferation zone, in the various initial phases of the oogenesis, were named oogonia, because its distinction requires cytological studies. Observations about the peripheral bodies of the germinaI cells prosecute by means of electron microscope and histochemical tecniques.
