We would like to thank Drs. Beverley & Derek Wills and Stefanie Komossa for useful and intensive discussions. We thank Dr. S. Komossa for giving us a preprint of her paper about NGC 5905 and her recent preprint on RX J0134.2-4258. Also we thank Drs. Thomas Boller, Joachim Siebert, Jules Halpern and our referee for their comments and suggestions on the manuscript. We wish to thank Barry Clark and the NRAO staff for granting us 1 hour of engineering time on short notice to obtain the new radio observations which confirmed the association of the PMN radio source with RX J0134.2-4258. This research has made use of the NASA/IPAC Extragalactic Database (NED) which is operated by the Jet Propulsion Laboratory, Caltech, under contract with the National Aeronautics and Space Administration. Also we used the IRAS data request of the Infrared Processing and Analysis Center (IPAC) Caltech. We have made use of the ROSAT Data Archive of the Max-Planck-Institut für Extraterrestrische Physik (MPE) at Garching, Germany. KML gratefully acknowledges support through NAG5-7971 (NASA LTSA). SALM acknowledges partial support by the Department of Energy at the Lawrence Livermore National Laboratory under contract W-7405-ENG-48 and from the NSF (grant AST-98-02791).
