On the basis of OAO-2 data, the presence of a depression has been established in the ultraviolet continuous spectra of 22 hot stars out of 134 that were analyzed. The depression is mainly in the region 2200-2400 A. However, the wavelength corresponding to the maximum of the depression drifts to shorter wavelengths on the transition to stars of earlier classes. The errors in taking into account the influence of interstellar absorption do not influence the final conclusions with regard to the presence or absence of depression. The obtained results confirm an earlier conclusion, namely, that a depression in the ultraviolet is a fairly common phenomenon among hot stars and that this depression can be regarded as a sensitive indicator of the presence of circumstellar clouds. 14 references.
