As expected, many X-ray sources discovered by ROSAT have been identified with previously unknown cataclysmic binaries (e.g., Motch et al. 1996). For a description of the ROSAT mission and the X-ray detectors (Position Sensitive Proportional Counter, PSPC, and High Resolution Imager, HRI) sensitive in the 0.1 - 2.4 keV band see Trümper (1983), Pfeffermann et al. (1986) and David et al. (1993), respectively. Here we report the discovery of a new cataclysmic variable near the position of a source from the ROSAT Galactic Plane Survey (RGPS; Motch et al. 1991). The source, RX J1910.8+2856, lies in Lyra at and is contained in the ROSAT Bright Source Catalogue (1RXS J191053.2+285622; Voges et al. 1996).
