The paper gives the results of preliminary spectral investigations made with the 6-m telescope for seven stellar objects identified in the First Byurakan Survey (FBS) on the basis of the ultraviolet excess in their spectra. We have classified six of these seven stars as cataclysmic variables. The objects are divided into subclasses: three are dwarf novas, one is a recurrent nova, and two are novalike. One of the stars, FBS 1031 + 590, is, on the basis of all features of the spectrum and the nature of its variability, a polar. Finding charts and samples of spectral scans of the stars are given.
