Results indicated that more individuals characterized by red dorsal ground color have been found in the western half of Japan and that such variants can be classified into three types. The heredity of coloration in one of these variant types, that having numerous small black spots on dorsum, was examined in a series of hybridization experiments in captivity. The results strongly suggested that coloration of this variant type is inherited and recessive.
