We present optical spectroscopy of the dwarf nova HL Canis Majoris over aspan of four years. The observations were made during standstill, outburst, andquiescence. We determine an orbital period of 0.2167867 +/- 0.17 days,based on radial velocities determined from H-alpha, H-beta, and He I 5876emission. We also present equivalent widths of the spectral features inoutburst and in quiescence.Comment: 4 pages, 3 postscript figures, will be published in PASP July 200
