Seventy-four radial velocities and spectral types are given for a sample of late type dwarfs taken mainly from the U.S. Naval Observatory parallax catalogs. Fifty-two of the stars had no previously published velocities. Spectral types have been assigned, and space motions are computed using the newly determined radial velocities and previously published parallaxes and proper motions. Several high velocity stars are found, but one particularly interesting star (number 20 in the present list) is subluminous by approximately 2 mag while having a space motion of 384 km/s. In addition, the spectra of several stars appear unusual in exhibiting broadened or indistinct spectral features.
