Interstellar extinction observed in spectra of Be stars.
Evident differences between extinction laws observed in spectra of "normal" B type and Be stars are shown. The latter do not contain in many cases the prominent feature of the extinction curve - the 2200 Å bump. The results are derived both from multicolour (including the ultraviolet ANS) photometry and from TD-1 UV spectra. It is suggested that the observed peculiarities originiate in circumstellar shells which add their contributions to the interstellar reddening.
