Abstract
1.
1. Ten lots of Dugesia tigrina, each consisting of 300–600 individuals, were extracted according to the method of Anton and Sayre for catecholamines and the extracts subjected to thin-layer chromatography.
2.
2. Dopamine and lesser amounts of noradrenaline were found in the Dugesia extracts.
3.
3. One lot each of Procotyla fluviatilis and Phagocata oregonensis yielded detectable amounts only of dopamine.
4.
4. Dopamine appears to be the dominant catecholamine in these three species of planarians.
