Regions of copper ion concentration in later phases of the decorticated stage by barnacles exposed to 200 Cu++ for one hour, (a) In the cytoplasm of peripheral organelle cells, (b) In fascicular vacuoles of the cylindrical cells, (c) Within one lobule of the glandular labyrinth. fascicular inclusions within the cytoplasm of the cylindrical cells and were noted only in the latest phases of this stage when cell orientation is haphazard. We suggested previously that inclusions within these cells are reservoirs for histolyzed material to be employed in subsequent histogenesis and organogenesis. The deposition of copper in these inclusions implies a dynamic exchange with the ambient sea water and directs attention to a possible role of these cells in concentration of other ions from sea water during morphogenesis. Vital staining experiments also indicated a rapid exchange between parenchyma vacuoles and the medium during this stage. During the same phase at which these deposits were noted, but not in earlier specimens, some copper was detected in the cytoplasm of the cells in the peripheral.
