Horsley emended the two records to *Itunocelum to create an 'Eden promontory' in favor of a name for Bowness on Solway. And while this has been generally accepted as a name-form, few would endorse the assignment. None of that really matters, the orderly progression of names alone indicate that Iuliocenon should be at Moresby, and the Ulgill flows to Lowca Beck just above the Roman fort NX9821.
