The distribution of virial masses for nearby galaxy clusters is presented. The analysis is based on a data-set of 75 clusters, each with >20 members with measured redshifts within 1.5h^-1 Mpc. Having accounted for problems of incompleteness of the data-set, a power is finally fitted to the mass distribution. Constraints on the spectrum of primordial fluctuations are obtained.
