A family of triaxial mass models is described, for which the density is stratified on coaxial ellipsoids with varying axial ratios. The contours of constant projected density are almost perfect ellipses with ellpticity variations and isophote twists, but with no significant high-order residuals. These models are generalization of the triaxial models of Stark. An application to a real galaxy is presented.
