      a different type envelope. These remittances will be entered on the Remittance Register
      (SSA-124) maintained in the mailroom. The remittances, together with the register,
      will be hand-carried to the Deposit Clerk for verification. These items will be identified
      on the Remittance Register as “SMIB” in the right margin.
