The optical counterparts of 47 X-ray sources with previously unreported quasi-stellar objects are identified. The mean ratio of X-ray to optical luminosity of the sample agrees with that derived from X-ray observations of previously known QSOs, although the mean redshift of the sample is z=0.42, and thus the main luminosity of the objects (Mv=24) differs significantly from that of previous QSO surveys with similar optical thresholds. The steep luminosity function inferred indirectly from optical counts is confirmed. Reconciliation of the observed QSO luminosity function with optically and radio-selected QSO samples requires one of two significant stipulations. Either the space and luminosity distributions of QSOs become quite well specified, or the X-ray luminosity of the typical QSO falls short of that inferred by Zamorani et al. (1981).
