We searched for massive stars with Balmer emission consistent with magnetically confined circumstellar material. Archival spectroscopic and photometric data were investigated. HR7355 is a formerly unknown He-strong star showing Balmer emission. At V=6.02mag, it is one of the brightest objects simultaneously showing anomalous helium absorption and hydrogen emission. Among similar objects, only σOri E has so far been subjected to any systematic analysis of the circumstellar material responsible for the emission. We argue that the double-wave photometric period of 0.52d corresponds to the rotation period. In tandem with the high projected equatorial velocity, vsini=320km/s, this short period suggests that HR7355 is the most rapidly rotating He-strong star known to date; a class that was hitherto expected to host stars with slow to moderate rotation only.
