In order to check the results derived previously from purely photometric investigations of faint OB stars, we obtained image-tube spectra of 69 early-type stars in the Vela, Centaurus, Circinus, and Norma sections of the Milky Way. Besides, the study of the Vela and Norma regions was extended with new UBV photoelectric observations for 16 additional stars in Vela  and for 15 additional stars in Norma; spectral types were also obtained for 18 of these stars.
