This paper presents 50 QSOs discovered on objective prism plates taken with the UK Schmidt and confirmed with slit spectra from various telescopes. Only three of these QSOs have been reported previously. The redshifts range from 2.5 to 3.3 with z greater than or equal to 3.0 for 18 of them. Five of the objects are broad-absorption-line (BAL) QSOs and another five have some of the characteristics of the BALs such as a sharp blue edge on the N V or O VI emission line accompanied by heavy continuum absorption shortward of the Ly-alpha + N V emission, or Ly-alpha + N V emission dominated by N V which is as strong as C IV. All these phenomena imply higher ionization than typical QSO absorption lines, and from the similarities with the BAL QSOs suggest that the absorption is intrinsic to the QSO. The entire class is referred to as high-ionization absorption QSOs.
