Scientific paper

The elliptical galaxies NGC 5266, 0609-331, 0632-629, and 0641-412 show dust lanes along their minor axis. Spectroscopic kinematical findings are presented. All objects rotate about their short axis, orthogonal to the dust-lane rotation. The combination of kinematic data of the stars and of the dust lane allows conclusions to the intrinsic shape of the galaxies. Arguments for a triaxial, near prolate shape of NGC 5266 and 0609-331 are presented. These arguments are especially strong for 0609-331 which shows significant rotation about major axis and minor axis and minor axis as well.
