The Roman Map of Britain Uxelodunum Stanwix, Cumberland

Uxeludamo var. Uxelodiano (R&C 152) next
Praefectus alae Petrianae, [Uxeloduno] (ND xl₄₅) considering the surviving line to be the conflation of two
UXELODUM (Rudge Cup)
UXELODUNUM (Amiens patera)
UXELODUNUM (Staffordshire Cup)

I suggest that two lines in the Notitia Dignitatum were combined.

xl₄₅ Praefectus alae Petrianae, [Uxeloduno]
      [Prafectus numeri ...............], Petrianis
