  We observed an X-ray selected, deeply eclipsing cataclysmic variable IR Com
(=S 10932). We detected an outburst occurring on 1996 January 1. The light
curve of the outburst closely resembled that of a normal outburst of an SU
UMa-type dwarf nova, rather than that of an intermediate polar. Time-resolved
photometry during outburst showed that eclipses became systematically deeper
and narrower as the outburst faded. Full-orbit light curves in quiescence
showed little evidence of orbital humps or asymmetry of eclipses. In addition
to the presence of high--low transitions in quiescence, the overall behavior of
outbursts and characteristics of the eclipse profiles suggest that IR Com can
be best understood as a twin of HT Cas, a famous eclipsing SU UMa-type dwarf
nova with a number of peculiarities.
