The year saw war against the Aequi and the Labici which resulted, after the defeat of Papirius colleague Sergius, to the appointment of a dictator, Quintus Servilius Priscus Fidenas.
Servilius, the dictator, appointed his relative, Axilla, to the office of magister equitum, and together they defeated both their enemies resulting in the capture of Labici.
[3][4][5][6] Papirius was again elected as consular tribune in 416 BC, this time sharing the office with Aulus Sempronius Atratinus, Quintus Fabius Vibulanus and Spurius Nautius Rutilus.
Ogilvie, noting that the cognomen of Atratinus is otherwise unattested among the Papiria and seems to be exclusively used by another gens, the Sempronia, argues that the source of the Fasti Capitolini is corrupt at this point and "the original list of 411 will have been a college of three consular tribunes, Papirius, Sempronius and Nautius".
If Mugillanus is to be identified as the consul in 411 BC he would have shared the office with his former colleague Nautius in a consulship beset by pestillence and famine.
