The only strongly polarized cataclysmic variable discovered among the Palomar Green Survey objects is reported. Linear and circular polarimetry defined the orbital period at 113.56 minutes, the maximum linear polarization at about 2-5 percent, and the circular polarization varies between 0 and -12 percent. This is the first object to show substantial circular polarization at the time of the linear pulse, yet the circular polarization does reach zero at phase 0.5. Simultaneous UBVR photometry shows mild flickering and smooth variations which are roughly synchronous with the polarization. Infrared photometry indicates an energy distribution similar to AM Her. Spectroscopic results show noteworthy strong O III wavelength 3444, C II, and N III lines that may indicate unusual excitation or abundance effects or both. The radial velocities of the narrow emission components have semiamplitude K = 170 km/s and a positive-going zero crossing at magnetic phase 0.57. The broad emission component shows semiamplitude K = 230-330 km/s with a zero crossing near phase 0.35.
