Although the pattern of amino acid distribution in the proteins of these shell-fishes is relatively uniform, some slight differences are observed on several amino acids. The protein of abalone is rich in glycine, proline and arginine and poor in leucine, glutamic acid, tyrosine and lysine when compared with that of hard clam. It is also found that the tryptophan content of the hard clam protein is rather high.
These shell-fish proteins show a lower value of valine, methionine, phenylalanine, lysine and histidine than the muscle proteins of fish^{1, 2}) and crustaceans³) examined in our previous studies.

Succeeding to the previous papers^1-3), in which the amino acid composition of the proteins of fish and crustaceans was given, the present paper deals with the shell-fish proteins.
The minced edible part of a hard clam (Meretrix meretrix lusoria GMELIN) and that of an abalone (Haliotis gigantea GMELIN) were thoroughly extracted with boiling water acidulated with acetic acid (pH 4.5), ethanol and ether in order.
Amino acids in the proteins thus obtained were determined by the column chromatographic method using an ion-exchange resin and the results obtained are given in Table 3.
Although the pattern of amino acid distribution in the proteins of these shell-fishes is relatively uniform, some slight differences are observed on several amino acids. The protein of abalone is rich in glycine, proline and arginine and poor in leucine, glutamic acid, tyrosine and lysine when compared with that of hard clam. It is also found that the tryptophan content of the hard clam protein is rather high.
These shell-fish proteins show a lower value of valine, methionine, phenylalanine, lysine and histidine than the muscle proteins of fish^{1, 2)} and crustaceans³⁾ examined in our previous studies.
