Abstract:

We present a catalogue of velocities for 551 galaxies (and give the coordinates of 39 stars misclassified as galaxies in our photometric plate catalogue) in a region covering about (0.940.94 Mpc for an average redshift of 0.0555, assuming H₀=50 km s^-1 Mpc^-1) in the direction of the rich cluster ABCG85. This catalogue includes previously published redshifts by Beers et al. (1991) and Malumuth et al. (1992), together with our 367 new measurements. A total of 305 galaxies have velocities in the interval 13350-20000 km s^-1, and will be considered as members of the cluster. ABCG85 therefore becomes one of the clusters with the highest number of measured redshifts; its optical properties are being investigated in a companion paper.
