The concept "semicommensurate", introduced in the paper [J. Phys. Soc. Jpn.53 (1984) 1775], is explained again. (Abbreviations Pr, CF, IF and SF are usedfor a or the prototypic phase, .perfectly commensurate ferroic phase, perfectlyincommensurate ferroic phase and semicommensurate ferroic phase, respec-tively.) Although it is impossible that, on cooling, Pr is changed to SF by second-order transition earlier than to IF, it is possible that IF, which succeeds Pr, ischanged to SF by second-order transition earlier than to CF by first-order transi-lion. This possibility is accounted for, using not both the soft order parametersand a supporting hard order parameter but only the former (unlike in the pre-ceding paper).
