The photometric behavior in the uvby system of the Ap star 46 Eri is analyzed on the basis of new data. The revised period is P = 3.798777 + or - 0.000015 d. Knowledge of the accurate light-curve of 46 Eri makes it possible to refine data on the multiperiodic B5III variable star 210 G. Eri, which was used as a comparison for 46 Eri. Four periods, all of the order of four days, are found with P(1) = 3.9215 d standing out clearly. This value is very large compared to those of other mid-B variables.
