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
(0.94×0.94 Mpc for an average redshift of 0.0555, assuming
H0=50 km s-1 Mpc-1) in the direction of the rich cluster
ABCG 85. 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.ABCG 85 therefore becomes one of the clusters
with the highest number of measured redshifts; its optical properties
are being investigated in a companion paper.
