Two Batavi Iuniores?

[Liam Boyle]

So for some reason, the Batavian units really interest me. And I recently became really interested in the army of the Late Empire. Anyways, I noticed that the Batavi Iuniores are listed twice in the Notitia Dignitatum. Some books and websites I've come across claim that there were the Batavi Iuniores and another unit called the Batavi Iuniores Britones (or Batavi Iuniores Britanniciani). So were there two Batavi Iuniores? Or is it just an error made when the ND was first made or copied?




Here are some of the websites and books:
