Abstract: Separated by paper chromatography, eight amino acid were identified in the mantle cavity fluid of Balanus glandula. They are glutamic acid, lysine, proline, alanine, valine, serine, leucine, and arginine. These amino acid do not compare idntically with those found in the blood of the same organism, one main difference being the presence of hydroxyproline and traces of proline in the blood, and the absence of hydroxyproline and large concentrations of proline in the mantle cavity fluid. Reasons from the presence of amino acids in the mantle cavity are discussed.
