Radial velocities and space motions are presented for G7-17, LHS 453, LHS 489, and LHS 3382, cool, extremely metal-poor subdwarfs. For G7-17 and LHS 489, trigonometric parallaxes are available; for the others, very conservative photometric parallaxes were adopted. The halo color-luminosity relation from which these were derived is such that these objects are as much as 3 mag fainter than old-disk stars of the same (R-I)K. All of them appear to be bound to the Galaxy, although the orbit of LHS 3382 verges on chaotic.
