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 LXXVIII

Canon LXXVIII.  (Greek lxxxi.)

Of the Church of Hippo-Diarrhytus.

It further seemed good that since the destitution of the Church of Hippo-Diarrhytus should no longer be neglected, and the churches there are retained by those who have declined the infamous communion of Equitius, that certain bishops be sent from the present council, viz.:  Reginus, Alypius, Augustine, Maternus, Theasius, Evodius, Placian, Urban, Valerius, Ambivius, Fortunatus, Quodvultdeus, Honoratus, Januarius, Aptus, Honoratus, Ampelius, Victorian, Evangelus and Rogation; and when those had been gathered together, and those had been corrected who with culpable pertinacity were of opinion that this flight of the same Equitius should be waited for, let a bishop be ordained for them by the vote of all.  But if these should not be willing to consider peace, let them not prevent the choosing for ordination of a bishop, for the advantage of the church which has been so long destitute.

Notes.

Ancient Epitome of Canon LXXVIII.

It seemed good that, after Equitius had been condemned by the universal vote, a bishop of Hippo should be elected, and that they should in no way impede the ordination of a prelate for that church.

p. 481 This canon was likewise probably an appendix, to Canon xiij, of the Synod of Carthage of September 13th, 401, according to Hefele.

Here the place of election and consecration seems to be the vacant see.
