We present spectroscopic and photometric data for 920 galaxies selected in 68fields of the Aquarius Cluster Catalog. Typically the 15 brightest candidatemembers with magnitudes in the range 16 < b_J < 21 were selected forobservations, and ~ 71% turn out to be cluster members. Using the new redshiftdeterminations we assign galaxies to groups and clusters, and by including datafrom the literature we calculate systemic velocities and velocity dispersionsfor 74 clusters, each with redshifts measured for at least 6 individualgalaxies.Comment: 16 pages, including 8 figures and 6 tables; to be published on Astronomical Journal, January/2005 issu
