Here, Dr. Gwynn observes, is a memorandum combining in continuous form several unconnected passages in Tírechán. “It is reasonable to infer that the tradition condensed into this memorandum was known to Tírechán; that he endeavoured to work it into his history by breaking it up into pieces and inserting them where he judged best.” 14. _King Amolngaid: Date of his Reign_ The death of Amolngaid, king of Connaught, is not noticed in the _Ann. Ult._, but is recorded _s.a._ 449 in the _Annals of the Four Masters_, and must have been derived from older Annals. Probably it was given by Tigernach (this part of his work is not preserved), who generally records the changes in the succession in Connaught. We cannot indeed infer that A.D. 449 was the precise year designated in the source of the Four Masters, because at this period their dates are not very accurate, as can be shown by a comparison with the _Annals of Ulster_. But we can consider it as an approximation to the date assigned by the older Annals. The extant lists of the kings of Connaught, from Amolngaid to Aed (son of Eochaid Tirmcharna), ob. A.D. 577, are hopelessly confused. The material which I have examined consists of (1) the names and dates in the Annals (_Ann. Ult._ and Tigernach); (2) List in _Book of Leinster_, 41a; (3) List in MS. Laud, 610, f. 116 rᵒ b; (4) (_a_) prose list, (_b_) poetical catalogue by O’Duinn, in _Book of Ballymote_, 57a, 58a. I owe the translation of O’Duinn’s poem to the kindness of Mr. E. J. Gwynn.
