The (UBVRI) photometry of all M dwarfs which are within 10degree of the South Galactic Pole and brighter than visual magnitude 15, and which have annual proper motions greater than 0/sup prime/./sub /096, are discussed. The observations themselves are listed and discussed in a recent Astrophysical Journal Supplement. The luminosity function is found to be very similar, in the overlapping sections, to that previously derived spectrophotometrically from the M stars near the Sun, and the extension to M/subV/ near +13 mag indicates that this luminosity is near the peak of that function. No support is found in these data for the recently suggested superabundance of low velocity M stars near the Sun. (AIP)
