The authors have searched for the infrared emission from twenty-three selected areas (4arcmin×4arcmin) around the unidentified southern AFGL sources. Sources with a significant signal-to-noise ratio have been found in almost all the selected areas; the total number of sources detected is 42. JHKLM photometry has been carried out for the seventeen sources detected at the highest confidence level. The analysis of the infrared energy distribution of the reddest objects found in the authors' survey, suggests the association of ten ground-based sources with the relative AFGL sources reported in the catalog of Price and Walker (1976). A brief discussion about the nature of these objects is reported.
