  We report the discovery of 141 new high proper motion systems (1.0"/yr > mu
>= 0.4"/yr) in the southern sky (Declination = -90 degrees to -47 degrees)
brighter than UKST plate R_{59F} = 16.5 via our SuperCOSMOS-RECONS (SCR)
search. When combined with the nine systems having mu >= 1.0"/yr and/or late
spectral type from the initial phases of this effort (Hambly et al. 2004, Henry
et al. 2004), we find that 73 of the 150 total systems are moving faster than
0.5"/yr, and are therefore new members of the classic "LHS" (Luyten Half
Second) sample. These constitute a 21% increase in the sample of stars with mu
>= 0.5"/yr in the declination region searched, thereby comprising an important
addition to this long-neglected region of the sky.
  Distance estimates are provided for the entire sample, based upon a
combination of photographic plate magnitudes and 2MASS photometry, using the
relations presented in Hambly et al. (2004) for the presumed main sequence
stars. Three systems are anticipated to be within 10 pc, and an additional 15
are within 25 pc. Eight of these 18 nearby systems have proper motions falling
between 0.4"/yr and 0.6"/yr, hinting at a large population of nearby stars with
fast, but not extremely high, proper motions that have not been thoroughly
investigated.
