Data are presented on six notable quasars selected from those observed recently with an SIT vidicon spectrometer on 1.5-m and 4-m telescopes. The four objects with z between 3.0 and 3.25 have continuum magnitudes brighter than 18 and include Q0420-388 with m = 16.9, which is the brightest and most luminous quasar with z greater than 3 yet discovered. The two quasars with z of about 2.2 are at the opposite extremes of brightness in the survey. One, with m = 16.5, has weak Ly-alpha emission. The other has declined 2 mag from its brightness on the Schmidt discovery plate to m = 20.4. It has the strongest emission lines yet found in the survey.
