Sauer et al. (Phys. Rev. B 34, 9023, 1986) have recently determined the band offsets of lattice-matched In0.53Ga0.47As-InP heterojunctions. Cardona and Christensen show that the valence-band offset found by those authors (0.254 eV) agrees with that estimated by the dielectric-midgap- point method (M. Cardona and N.E. Christensen, Phys. Rev. B 35, 6182, 1987).
