The paper presents redshifts and central velocity dispersions (sigma) from observations with the FLEX-based multiobject system on the William Herschel 4.2-m telescope for early-type galaxies in three rich clusters, Abell 194, Abell 2199, and Abell 2634. In particular, for Abell 2634, a cluster distance is derived that gives a highly significant peculiar velocity of -3400 + or - 600 km/s. It is noted that the IR Tully-Fisher distance for Abell 2634 spiral galaxies implies only a small peculiar velocity. It is argued that the effects of tidal stripping in the core of this cD dominated cluster may have caused a zero-point difference in the D-sigma relation and hence the large peculiar motion observed here for Abell 2634 may be spurious.
