We present the results of an HST [OIII] study of the narrow line regions (NLRs) of Seyfert galaxies. Our sample consists of Seyfert galaxies selected from nearly isotropic properties, their far-infrared fluxes and warm infrared colors. We discuss the luminosities, projected linear extents, and morphologies of the NLRs of these galaxies as well as the agreement of these properties with the Unified Model. We find that while the Unified Model accurately predicts many of the observed characteristics of the NLRs, certain observed morphologies can not be explained by simple models and require a more careful examination.
