We present 178 radial velocity measurements for 166 late-type stars selected from the Luyten half-second (LHS) proper motion catalog. Space velocities are given for all but two of them. Most of the stars lie within 25 pc of the Sun, but the list includes a handful of high-velocity transients from the halo population. None of the derived space velocities is high enough, however, to provide any constraint on the escape speed at the solar circle. Twenty-six stars are discussed in somewhat more detail, and evidence is adduced that several of them may be velocity variables.
