This Regula Eremitica seu praescripta fratribus in eremo degentibus, as Colgan calls it, was edited by Reeves in the appendix of his edition of Primate Colton's Visitation of the Diocese of Derry, p. 109, from a transcript by Michael O'Clery, and accompanied by O'Curry's English translation. The importance of this old document justifies the publication of a second copy, on fo. 40 b 2 of the Oxford Codex [=Rawlinson B 512] to correct various errors in O'Clery's transcript or Reeves' edition.
