The construction of a new sample of 476 ROSAT clusters of galaxies obtained in the southern hemisphere using the ROSAT All-Sky Survey is described. Preliminary results illustrate the homogeneous sampling of the clusters out to redshifts z 0:3. The sample is used for statistical studies giving observational constraints on diierent cosmological structure formation scenarios.
