ANTIQUA CUSTOMA, Eng. law. A duty or imposition which was collected on wool, wool-felts, and leather, was so called. This custom was called nova customa until the 22 Edw. I., when the king, without parliament, set a new imposition of 40s. a sack, and then, for the first time, the nova customa went by the name of antiqua customa. Bac. Ab. Smuggling &c. B.
