This paper examines a subset of objects from the USNO-B1 catalog with listed proper motions between 1 0 and 5 0 yr -1 . We look at the degree of contamination within this range of proper motions and point out the major sources of spurious high proper motion objects. Roughly 0.1% of the objects in the USNO-B1 catalog with listed motions between 1 0 and 5 0 yr -1 are real. Comparison with the revised version of Luyten's Half-Second Catalogue indicates that USNO-B1 is only about 47% complete for stars in this range. Preliminary studies indicate that there may be a dip in completeness in USNO-B1 for objects with motions near 0 1 yr -1 . We also present two new stars with motions between 1 0 and 5 0 yr -1 , 36 new stars with confirmed motions between 0 1 and 1 0 yr -1 , several new common proper motion pairs, and the recovery of LHS 237a (VBs3).
