We present spectra of PKS 2155--304 obtained by the Extreme Ultraviolet Explorer (EUVE) satellite during two long ($>100,000$~s) observations taken three weeks apart. Each spectrum shows pronounced, but different, absorption features. We discuss mechanisms that might produce these features. We use these results to rule out various models for the object that have been suggested based on X-ray results. This work has been supported by NASA contract NAS5-30180.
