We present the discovery of about 100 new high-proper motion stars in the region between 0^h^ and 7^h^ in right ascension and -63{deg} and -32{deg} in declination, with proper motions between 0.3 and 1.0arcsec/yr. In addition we have obtained improved coordinates and photographic photometry for another about 100 already known high-proper motion stars in the same region. In this study we have made use of APM measurements of UKST survey plates in 40 survey fields. Using all available information (position, proper motion, photographic R magnitude and B_J_-R colour index), we draw some preliminary conclusions on the nature of the new high-proper motion stars, particularly of extreme cases.
