A catalogue of 388 new possible planetary nebulae was selected by Preite-Martinez (1988) from the IRAS Point Source Catalogue. These unidentified sources have IRAS colours in the range F(12)/F(25) ≤ 0.35 and F(25)/F(60) ≥ 0.35, and are located in the proximity of the galactic equator (|b| ≤ 15°). In order to identify these IRAS sources we have undertaken a programme of near-IR observations using an InSb photometer and a near-IR camera. We report here on results relative to four of these sources.
