Summary Adult Cichlasoma biocellatum were kept in deionized water, 25% sea-water and tap-water. The mucous cells in the epithelium of the gills and the buccal floor were not affected by the osmotic experiments. In animals kept in deionized water the mucous cells in the skin remained unaffected, but the ionocytes (chloride cells) in the gills were strongly stimulated. Keeping the animals in salt water led to a strong regression of the epidermis including the mucous cells, and of the ionocytes. The regression could be counteracted by prolactin injections. The changes in the skin and the ionocytes could be correlated with the activity of the prolactin producing cells in the adenohypophysis. It is suggested that the epidermis and its mucous cells as well as the ionocytes are under prolactin control.
