E. ; Barbuy, B. ; Dos Anjos, S. Abstract Velocity dispersions and Mg_2_ indices were measured from CCD spectra of 13 box-shaped galaxies and 5 ellipticals. Evidences for a different relation between velocity dispersion and metallicity, relative to ellipticals, was found for our S0 sample; we attribute this difference to the S0 disk component, affecting both the mean velocity dispersion and mean metallicity. In a tentative to reproduce the integrated bulge spectra of our sample galaxies, we have built composite spectra using a grid of synthetic spectra, where the basic parameters were assumed to be similar to those of galactic bulge globular clusters.
