					<para>
    We present redshifts and stellar velocity dispersions for about 40
    galaxies in each of 14 rich clusters from the southern cluster survey
    of Abell &amp; Corwin (1983, Early Evolution of the Universe and Its
    Present Structure, p.179, Eds. Abell &amp; Chincarini, Reidel, Dordrecht,
    Holland). The clusters cover a wide range of richnesses and Abell and
    Bautz-Morgan types, our aim being to compile a large, homogeneous
    database for examining and comparing dynamical phenomena and
    morphological properties. Further papers will present photometry for
    the clusters and an analysis of the database.</para></abstract>
