Through the optical cross identifications made by the 2.16m telescope at Beijing Astronomical Observatory, seven ROSAT-VLA selected X-ray sources, 2318+304, 2319+161, 2322+343, 2338+212, 0109+181, 0152+014, 0326+022, were found to be BL Lac objects, and a ROSAT-VLA selected X-ray source, 0112+381, was found to be a quasar with a red-shift of 0.331±0.0015. The optical magnitudes were obtained at the 1.0m telescope of the Yunnan Observatory and the 1.56m telescope of the Shanghai Astronomical Observatory.
