Passage 8.27.5
τὸ μὲν δὴ ἄλλο Ἀρκαδικὸν οὔτε τι παρέλυε τοῦ κοινοῦ δόγματος καὶ συνελέγοντο ἐς τὴν Μεγάλην πόλιν σπουδῇ· Λυκαιᾶται δὲ καὶ Τρικολωνεῖς καὶ Λυκοσουρεῖς τε καὶ Τραπεζούντιοι μετεβάλοντο Ἀρκάδων μόνοι, καὶ---οὐ γὰρ συνεχώρουν ἔτι τὰ ἄστη τὰ ἀρχαῖα ἐκλιπεῖν--- οἱ μὲν αὐτῶν καὶ ἄκοντες ἀνάγκῃ κατήγοντο ἐς τὴν Μεγάλην πόλιν, Τραπεζούντιοι δὲ ἐκ Πελοποννήσου
The rest of Arcadia did not in any way disregard the common resolution, but earnestly gathered together into the Great City. Only the Lycaeans, the Tricolonians, the Lycosoureans, and the Trapezuntians among the Arcadians changed their stance. For they refused henceforth to abandon their ancient towns; yet some of them were forcibly compelled against their will to remove to the Great City, whereas the Trapezuntians left the Peloponnesus entirely.
