Abstract
New spectroscopic data for a sample of early-type galaxies reveal significant anti-correlations between near-infrared Ca ii triplet indices and velocity dispersion. These relations, when interpreted in the light of our recent evolutionary synthesis model predictions, suggest the existence of important Ca underabundances with respect to Fe and/or an increase of the dwarf to giant stars ratio along the mass sequence of ellipticals.
