Photometric and spectroscopic observations of a new cataclysmic variable designated tentatively as 1329-294 suggest that it is a dwarf nova with orbital period of 0.13688 day. Its spectrum shows both hydrogen emission lines and absorption lines of late type dwarf secondary. Our measured radial-velocity amplitudes of the two components lead to a q-value of about 0.25. As the most probable parameters of the system we suggest: M1 = 1.4 solar mass, M2 = 0.4 solar mass, i = 35 deg.
