Abstract: Oxygen consumptions were determined with the Winkler method. The Barker and Summerson method was used for lactic acid determinations. The oxygen consumption by Tegula funebralis continues in water of low oxygen content, but at a much reduced rate. Lactic acid does not accumulate in excessive amounts until the animal has been under conditions of low oxygen tension for periods in excess of 160 hours. It appears that both sessation of physical activity and a continued low extraction of oxygen from the environment tend to suppress the accumulation of lactic acid when the animal is in waters of low oxygen content.
