Muscle proteins of 170 specimens of A. rochei and 11 specimens of A. thazard collected from the coastal region of Kochi Prefecture during June to August, 1970 were analyzed by the starch gel electrophoresis. 1. No individual variation can be recognized in the starch gel electropherograms of 11 specimens of A. thazard. 2. All the specimens of A. rochei fitted into one of three phenotypic protein patterns without exception. 3. It is postulated that these three phenotypes are controlled by two codominant alleles. 4. The distribution of three phenotypes was shown to be independent by age and sex. 5. The close agreement of the observed values and expected values calculated according to the HARDY-WEINBERG law strongly suggested that the phenotypic polymorphism is controlled by two codominant alleles and the samples were obtained from one MENDERIAN population. 6. The existence of hybrid protein in AB type shows that these proteins (6, 7 and 8) are of dimer type.
