Abstract
Spectral types are determined from low resolution optical spectra of 40 IRA
S sources with far-infrared colours similar to planetary nebulae, The prese
nce of circumstellar dust, high galactic latitude, and early supergiant or
giant spectral type, sometimes with emission in the Balmer lines, indicate
that some of these stars are low mass stars in the post-AGB stage of evolut
ion.
