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. The spectroscopic observations dealt mainly with stars brighter than B = 13.0 mag, while the photometric data had a limiting magnitude of about B = 15.0 mag. The present study lends support to the existence of groups of OB stars already suggested by the photometry and adds new members to them. The association of some of these groups, in particular a very distant one in Circinus, with WR stars is likely. Several stars seem to be affected by anomalous extinction.
