During our 1612 MHz survey of IRAS sources in Parkes, Australia, we found two objects with very large expansion velocities : IRAS15405-4945 and IRAS16342-3814 (P. te Lintel Hekkert et al. 1988, Astron. Astrophys. (Letters), in press.). These two sources and the well known source, OH231.8 + 4.2 , were discovered to have almost identical IRAS colours. The spectra of the three sources could be fitted with a 100 (±15) K black body curve. We than selected, using the IRAS colour-colour plot, a number of bright sources ( F (60 μm) > 25. Jy ) with similar colours to OH231.8 + 4.2 and IRAS16342-3814 . A small survey of about 150 sources was started in the last week of June and will be finished at the end of July 1988. Using the radio telescope in Nançay , we observed all four OH maser transitions, with the hunderd meter radio telescope at Effelsberg only 1612 MHz was observed, the sources found at Nançay were confirmed in Bonn and vice versa. From the preliminary analyses of the first 40 observations six sources were found of which three were not known before.
