Summary In land-pulmonate gasteropod Papillifera bidens a rather frequent modality of degeneration of the oocytes is characterized by the fact that at first wholly dissolve both cytoplasm and nucleus, while the nucleolus remains to all appearance intact, to degenerate only later on. In the process of spermiogenesis the function of nurse cells sometimes seems to be displayed by oocytes.
