A previous paper [J. Phys. Soc. Jpn. 54 (1985) 4213] indicated the possibility of atransition from an incommensurate phase having constant plaase differences to anincommensurate phase having varying phase differences. Following that paper, thispaper indicates that the latter phase, viz., the incommensurate phase of the varyingphase difference type should be ferroelectric. Since this phase is not semicommen-surate, it is a new type of simultaneously incommensurate and ferroelectric phase. Itspolar direction agrees with the incommensurate direction and hence differs from thepolar direction of the corresponding commensurate ferroelectric phase. The expres-sions of the temperature dependences of spontaneous polarization and susceptibilityare deduced.
