We point out that the data used in the sdg boson model calculations by Devi and Kota [Phys. Rev. C 45, 2238 (1992)] can be equally well described by the much simpler sd boson model. We present additional data for the Sm isotopes which cannot be explained in the sd model and hence may justify such an extension to the sdg bosons. We also comment on the form of the Hamiltonian and the transition operators used in this paper.
