We report 1606 new proper motion systems in the southern sky ( declinations - 90 \arcdeg to - 47 \arcdeg ) with 0 \farcs 40 yr ^ { -1 } > \mu \geq 0 \farcs 18 yr ^ { -1 } .
This effort is a continuation of the SuperCOSMOS-RECONS ( SCR ) proper motion search to lower proper motions than reported in Papers VIII , X , XII , and XV in this series .
Distance estimates are presented for the new systems , assuming that all stars are on the main sequence .
We find that 31 systems are within 25 pc , including two systems — SCR 0838-5855 and SCR 1826-6542 — we anticipate to be within 10 pc .
These new discoveries constitute a more than ten-fold increase in new systems found in the same region of sky searched for systems with \mu \geq 0 \farcs 40 yr ^ { -1 } , suggesting a happy hunting ground for new nearby slower proper motion systems in the region just north ( declinations - 47 \arcdeg to 0 \arcdeg ) , much of which has not been rigorously searched during previous efforts .
