Radial velocities have been obtained for 20 of the stars in Sanduleak's catalog. These are combined with photometric parallaxes and published proper motions to obtain space velocities and velocity dispersions. The space density is also estimated. The velocity dispersions and the space density appear to be "normal," i.e., there is no evidence for an excess density of low-velocity M dwarfs.
