For each galaxy we examine the case for systemic rotation, derive central stellar velocity dispersions sigma and photometric ellipticities epsilon. Using morphological classifications obtained via Hubble Space Telescope imaging as the basis, we explore the utility of our kinematic quantities in distinguishing between pressure-supported ellipticals and rotationally supported lenticulars (S0s). Description: The primary data set for this paper is a comprehensive Keck spectroscopic and HST imaging (F814W) survey of morphologically selected spheroidals in two clusters, Cl 0024+16 (z=0.40) and MS 0451-03 (z=0.54).
