title: The structure and cytochemistry of the oocytes in the crab Xantho bidentatus Milne Edwards.
abstract: In the development of the oocytes of xantho bidentatus four stages could be distinguished. In stage I the cytoplasm is homogenous, in state II a perinuclear ring is formed, in stage III oocytes round bodies which are carbohydrate-protein complexes appear near the peripheri. These bodies occupy the oocyte completely in the stage IV oocyte. There are two types of bodies in the oocyte, big oval or round bodies which are carbohydrate-protein complexes and smaller bodies in between the oval bodies. These smaller bodies are lipid bodies. In stage I and II the cytoplasm is rich in RNA and in stages III and IV the cytoplasm is full of carbohydrates, proteins and lipids.
