The results of spectroscopic observations of 363 starlike objects from the Second Byurakan Survey (SBS) are reported. This SBS subsample has proved to be a rich source of newly identified quasars, Seyfert-type galaxies, degenerate stars, and hot subdwarfs. In the subsample studied here, we identified 35 new QSOs, 142 white dwarfs (the majority of which, 114, are of DA type), 55 subdwarfs (29 of which are sdB-type stars), 10 horizontal-branch blue stars, 16 normal or horizontal-branch stars, 54 G-type and 25 F-type stars, two objects with composite spectra, four cataclysmic variables, two peculiar emission-line stars, 17 objects with continuous spectra, as well as one planetary nebula. Among the 35 QSOs, we have found two broad absorption line (BAL) QSOs, namely, SBS 1423+500 and SBS 1435+500A. Magnitudes, redshifts, and slit spectra for all QSOs, and also some typical spectra of the peculiar stars, are presented. We estimate the minimum surface density of bright QSOs in the redshift range 0.3<z<2.2 to be 0.05 deg^–2 for B<17.0 mag and 0.10 deg^–2 for B<17.5 mag.
