Abstract

We discuss the properties of the HI in low-luminosity early-type galaxies. The morphology of the HI is more regular than that of the HI in many more-luminous early-type galaxies. The HI is always distributed in a disk and is more centrally concentrated. The central HI surface densities are higher than in luminous early-type galaxies and are high enough for star formation to occur.
