We propose to obtain central region K-band spectra for a sample of N ~ 30 field elliptical galaxies. An analysis of the central near-IR colors of these galaxies suggests that some of these galaxies may contain first-ascent giant branches (FGB) similar to the unusual FGB seen in the metal-rich Galactic globular clusters Liller 1 and NGC 6440. We wish to test this hypothesis by measuring the equivalent widths of the Na I 2.207(micron) and Ca I 2.263(micron) as well as the CO 2.36(micron) index. These new EW and CO index measurements will be compared to previously published data for K and M giants in the Local Solar Neighborhood, Baade's Window, and the Liller 1 and NGC 6440 clusters. These spectra can also be used to assess cosmic dispersion in the elliptical galaxy stellar population properties, which has important implications for SBF distance measurements and the study of high- redshift galaxies.
