4. P.Maenius, is mentioned by Livy as consular tribune in B. C. 400, and again in B. C. 396 (Liv. 5.12, 18). The name, however, is written variously in the manuscripts. Alschefski, the latest editor of Livy, reads P. Manlius in the former of these years, but retains P. Maenius in the latter. In the Fasti Capitolini the name Maenius does not occur in either of these years, but instead of it we have P. Manlius Vulso, in B. C. 400, and Q. Manlius Vulso, in B. C. 396. The names in Diodorus (14.47, 90) differ again; and it seems to be impossible to reconcile the conflicting statements. In any case Livy is in error in designating Maelius and his colleagues as patricians.
