MK spectral classifications are given for 24 stars of types B and A in Fehrenbach's selected area No.4 (l = 73, 94°, b = +1.07°) for radial velocity investigations. The spectroscopic observations were made with the Marly spectrograph at the 120 cm telescope of Haute Provence Observatory. A spectral atlas of the standard stars is given, and the main criteria for classification are described. Many of the target stars have broad lines and one of them, HD 192605 is especially interesting, having a large Balmer progression of radial velocity.
