SUMMARY. The effect of surface‐active agents on the permeability, survival, and pseudopod formation of the rhizopod, Pelomyxa carolinensis , was studied. Surfactants increased the rate of uptake of Na 22 in almost all instances. Tweens which lower surface tension, stimulated or caused pseudopod formation; Tween 80 was the least toxic. The fatty acid component as well as the hydrophile‐lipophile balance of the surfactant may influence the rate.
