Arguments are presented against the adoption of an early B-red giant combination for the Φ Persei system. Velocity curves of the primary and secondary components based on the measures of the He I lines on nearly two hundred plates are shown and discussed insofar as orbital parameters and system membership are concerned. Evidence from the He I lines, the emission edges, shell absorptions, and underlying wide absorptions of the hydrogen lines indicate that the system is made up of a B1 primary and a B3 secondary, both of which are emission-line stars.
