Besides the new title Augustus, which traditional Roman office did Octavian continue to hold as part of the 27 BCE settlement?

Explanation

Octavian had held the consulship continuously since 31 BCE and kept it as part of the 27 BCE settlement, giving his authority a familiar constitutional face. He never held the dictatorship, which had been abolished as an office after Caesar's death, and he received tribunician power and the office of Pontifex Maximus only in later years, not as part of this settlement.
