The shells of the medicinal cowries, i.e. fresh shells of 17 species belonging to the family Cypraeidea were subjected to amino acid analysis with Hitachi Amino Acid Analyzer KLA-5. Assay samples were prepared according to the method previously reported. The results are listed in Tables I and II. In those shells amino acid composition seems to be quite irrelevant to their taxonomical classification. For example, amino acid compositions in the shells of Erosaria, Erronea and Mauritia, which are of the same genus, are quite different from each other. However, acidic amino acid composition therein seems to be more related to their taxonomical classification, as shown below. (1) Shells of Mauritia mauritiana, Monetaria annulus and Ravitrona caputserpentis contain a large amount of acidic amino acids. (2) Shells of Erosaria erosa, Ficadusta pulchella, Mauritia arabica and Palmadusta artuffeli contain fairly large amount of them. (3) Shells of Erosaria helvola, Fonda vitellus and Staphylaea nucleus contain only a trace of them. (4) Shells of Cypraea tigris, Erronea cylindrica and Erronea errones contain only a trace of aspartic acid and a large amount of glutamic acid. (5) Shells of the remaining species contain about the same amount of acidic amino acids as other amino acids.
