Abstract
1. 1. A fluorescent histochemical study of the nervous system of a starfish Patiriella calcar and a sea-urchin Heliocidaris erythrogramma was made to determine the distribution of mono-amines within the neurones. 2. 2. No mono-amines were detected in nerves innervating the skeletal or visceral muscles examined, neither were they found in sensory axons. No fluorescence was observed in the hyponeural tissue of the starfish radial nerve cord. 3. 3. Fluorescence in the axons and the cell bodies of other nerves coincided with the distribution of small granular vesicles demonstrated during electron microscope studies. The nerves containing mono-amines represent a class of interneurones, the function of which is not yet clear.
