We present 210 new measurements of the central absorption line-strength index for 87 early-type galaxies drawn from the Prugniel & Simien (1996) sample. 28 galaxies were not observed before. The results are compared to measurements published previously as available in HYPERCAT, and rescaled to the Lick system. The mean individual internal error on these measurements is and the mean external error is for this series of measurements.
Key words: galaxies: elliptical and lenticular, cD -- galaxies: fundamental parameters -- galaxies: stellar content
