Abstract
We use a set of 91 clusters observed in the course of the ESO Nearby A bell Cluster Survey (ENACS) and another 37 clusters taken from the lit erature in order tg construct a volume-limited sample of nearby cluste rs (z <0.08). We define the 3-dimensional Abell richness class R(3D) a nd we evaluate the spatial density of clusters with R(3D)greater than or equal to 1. For a subset of 43 clusters with N greater than or equa l to 10 members and with richness class R(3D)greater than or equal to 1 we evaluate the distribution function of the cluster velocity disper sions.
