  The transverse axial vector and vector anomalies in four-dimensional U(1)
gauge theories studied in [10] is reexamined by means of perturbative methods.
The absence of transverse anomalies for both axial vector and vector current is
verified. We also show that the Pauli-Villars regularization and dimensional
regularization give the same result on the transverse anomaly of both axial
vector and vector current.
