The goal of this program has been to study the dynamics of the clusters, with emphasis on determining the nature and frequency of peculiar-velocity cD galaxies. In this paper we present redshifts for 762 galaxies in the fields of the rich Abell clusters A779, A1691, A1749, A1767, A1837, A1927, A2067, A2079, A2089, A2199, and A2666. We also present preliminary dynamical properties for these clusters using our measured redshifts. File Summary:

Note (1): [HO98] ACO NNNN NNN in Simbad Note (2): The symbols are: E: the velocity comes from measurements of emission lines only, rather than the cross-correlation of the absorption spectra A: presence of absorption in the Balmer series NM: foreground or background galaxy that is not a velocity member of the cluster cD: central cD galaxy. Is followed by the number of repeated independent observations of the cD redshift
