It has been reported that there appears to be little non-baryonic dark matter in some elliptical galaxies. We have studied a large number of elliptical galaxies and found a clear, previously unknown, correlation between their dark matter content and the ellipticity of their visible shape. At equal luminosities, flattened medium-size elliptical galaxies have on the average five times larger total mass than round ones. Such a correlation provides a new testing ground for models of dark matter and galaxy formation.
