This paper givesthe R magnitudes, coordinates (J2000) from USNO (V1.0), spectral typeclassifications, equivalent widths of LiI absorption andHα emission lines of all the X-ray sourcesinvestigated, and the proper motions and parallaxes of some of them, aswell as the spectra of the newly discovered WTTS. For the first time,the spatial distribution of a rather complete, ROSAT-discovered sampleof WTTS, including those identified from the ROSAT All-Sky Survey andPSPC pointing observations around one of the nearby star-forming regionshas been provided, together with a preliminary analysis.
