  We present a catalogue of velocities for 466 galaxies in the direction of the
cluster Abell 496, in a region covering about 160' x 160' (9.2 x 9.2 Mpc for an
average redshift for Abell 496 of 0.0331, assuming H$_0$=50 km s$^{-1}$
Mpc$^{-1}$). This catalogue includes previously published redshifts by Proust
et al. (1987), Quintana and Ramirez (1990) and Malumuth et al. (1992),
redshifts from the CfA redshift survey, together with our new measurements. A
total of 274 galaxies have velocities in the 7800-11800 km/s interval, and will
be considered as members of the cluster. Abell 496 therefore becomes one of the
few clusters with a high number of measured redshifts; its physical properties
are investigated in a companion paper.
