Multiwavelength studies of southern early type galaxiesObservations from an in progress program to study early type galaxies are presented. International Ultraviolet Explorer (IUE) spectra of the southern galaxies NGC 1326 and 1808 are presented and compared to IUE archival spectra of four galaxies of approximately similar morphological type. The targets were selected on the basis of their infrared astronomy satellite emission, peculiarities in their dust structure as revealed from charge coupled device frames and the presence of H I from 21 cm data. Preliminary results show large differences in stellar populations, and the presence of early spectral type stars are correlated with UV extinction and IR excess. Interpretation of the data is presented, discussing the correlations between extinction, gas content and stellar populations.
