By selecting 15 radial velocity confirmed members of Bo\\\"{o}tes III, along with a likely RR Lyrae member in the vicinity, we measure an error weighted mean proper motion of $(\\mu_{\\alpha} \\cos{\\delta}, \\mu_\\delta) = (-1.14, -0.98)\\pm(0.18, 0.20)$ mas/yr. We select and present further stars that may be Bo\\\"{o}tes III members based on their combined proper motion and position in the color magnitude diagram.
