Nicene and Post-Nicene Fathers, Ser. II, Vol. XIV:
The Canons of the Synods of Sardica, Carthage, Constantinople, and Carthage Under St. Cyprian, Which Canons Were Received by the Council in Trullo and Ratified by II. Nice.: Canon CXXVII

Canon CXXVII.  (Greek cxxviii.)

That bishops be not detained too long in council, let them choose three judges from themselves of the singular provinces.

Item, it seemed good, lest all the bishops who are assembled at a council be kept too long, that the whole synod should choose three judges of the several provinces; and they elected for the province of Carthage Vincent, Fortunatian, and Clarus; for the province of Numidia Alypius, Augustine, and Restitutus; for the province of Byzacena, with the holy Senex Donatian the Primate, Cresconius, Jocundus, and Æmilian; for Mauritania Sitephensis Severian, Asiaticus, and Donatus; for the Tripolitan province Plautius, who alone was sent as legate according to custom; all these were to take cognizance of all things with the holy senex Aurelius, from whom the whole council sought that he should subscribe all things done by the council whether acts or letters.  And they subscribed:  I, Aurelius, bishop of the church of Carthage consent to this decree and having read it sign my name.  Likewise also signed they all.

Ancient Epitome of Canon CXXVII.

Whenever the bishops who come to synod can remain no longer in attendance, let three be chosen from each province.

This is Canon xix. of Carthage, a.d. 418.

Johnson.

Two Sancti Senes mentioned, who we are sure were both primates.  See can. 100 (104).

See can. 14.

And here we have an ancient precedent for synods delegating their authority to a committee, with the primate of all Africa at the head of it.

Item, at this council there was present a legation from the Roman Church.

After the consulate of the most glorious emperors Honorius for the XIIth. time and Theodosius for the VIIIth., Augusti, on the III. Calends of June, at Carthage, in the Secretarium of the restored basilica, when Aurelius the bishop together with Faustinus of the church of Potentia in the Italian province of Picenum, a legate of the Roman Church, Vincent of Calvita 483 (Culositanus), Fortunatian of Naples, Marianus Uzipparenp. 504 sis, Adeodatus of Simidica, Pentadius of Carpi, Rufinian of Muzuba, Prætextatus of Sicily, Quodvultdeus of Veri (Verensis), Candidus of Abbirita, Gallonian of Utica, legates of the proconsular province; Alypius of Tagaste, Augustine of Hippo Regia and Posidonius of Calama, legates of the province of Numidia; Maximian of Aquæ, Jocundus of Sufetula, and Hilary of Horrea-Cascilia, legates of the province of Byzacena; Novatus of Sitifi and Leo of Mocta, legates of the province of Mauritania Sitiphensis; Ninellus of Rusucarrum, Laurence of Icosium and Numerian of Rusgunium, legates of the Province of Mauritania Cæsariensis, the judges chosen by the plenary council, had taken their seats, the deacons standing by, and when, after certain things had been accomplished, many bishops complained that it was not possible for them to wait for the completion of the rest of the business to be treated of, and that they must hasten to their own churches; it seemed good to the whole council, that by all some should be chosen from each province who should remain to finish up what was left to be done.  And it came about that those were present whose subscriptions testify that they were present.
