Using the model of the Galaxy presented by Eggen, Lynden-Bell, and Sandage (1962), plane galactic orbits have been calculated for several southern high-velocity stars which possess parallax, proper motion, and radial velocity data. Extensive lists of both raw and computed data for these stars are included. Published values of U-B and B-V for some of these stars were used in plots of each of the orbital parameters versus U-B, B-V, or the ultraviolet excess. Also, a comparison is made between the H-R diagrams for the southern high-velocity star group and that of M3, a globular cluster, and again for M67, an old open cluster. The high-velocity star group is found to resemble an old open cluster more than a globular cluster.
