title: The fine structure of the oocyte and follicle cells of Lymnaea stagnalis, with special reference to the nutrition of the oocyte.
abstract: A description is given of the configuration of the surface membrane in the 3 zones of the polarised system of oocyte and follicle cells. Thus the cell contacts and relationships between these cells are considered and speculation on the significance of surface morphology in the passage of substances into the enlarging oocyte, is included.
