  We present results of intermediate resolution spectroscopy of 131 optical
counterparts to 115 ROSAT All-Sky Survey X-ray sources south of the
Taurus-Auriga dark cloud complex. These objects have been selected as candidate
young stars from a total of 1084 ROSAT sources in a about 300 square degree
area. We identify 30 objects as low-mass PMS stars on the basis of the Li 6708
doublet in their spectrum, a signature of their young age. All these stars have
a spectral type later than F7 and show spectral characteristics typical of
weak-line and post-T Tauri stars. The presence of young objects several parsecs
away from the regions of ongoing star formation is discussed in the light of
the current models of T Tauri dispersal.
