Radial velocities and expansions velocities (forbidden line O III, forbidden line O II, and He II) are measured for a sample of 64 southern Galactic planetary nebulae. Also, nebular electronic densities are derived from the forbidden line O II 3727, 3729 A double for 23 of these objects. The distance scale of Dopita et al. (1987) is used to derive distances to 33 Galactic nebulae. 50 references.
