Summary
Variations in the oxygen consumption and alterations in the ultrastructure of the body wall in the daughter sporocysts ofCercaria stunkardi andCercaria linearis during maintainance in artificial sea water as compared with those in modified Medium 199, indicate that the latter is an unsatisfactory nutrient medium. Similar changes in oxygen consumption, which suggest endogenous carbohydrate and lipid utilization together with autolysis, occur in the nutrient and non-nutrient media. Autolysis in the body wall of the sporocysts progresses, nearly to complete destruction, with almost equal rapidity in both media. The contained cercariae, however, remain healthy and appear to consume most of the absorbed oxygen.
