AbstractWe present low-resolution spectra of 486 IRAS point sources with Fv(12 μm) in the range 20-40 Jy. This is part of an effort to extract and classify spectra that were not included in the Atlas of Low-Resolution Spectra and represents an extension of the earlier work by Volk & Cohen which covers sources with Fv(12 μm) > 40 Jy. The spectra have been examined by eye and classified into nine groups based on the spectral morphology. This new classification scheme is compared with the mechanical classification of the Atlas, and the differences are noted. Oxygen-rich stars on the asymptotic giant branch make up 33% of the sample. Solid state features dominate the spectra of most sources. We find that the nature of the sources as implied by the present spectral classification is consistent with the classifications based on broad-band colors of the sources.
