Collina, Esquilina, Palatina and Suburana are "urban" tribes, the remainder "rustic". The total of 35 was completed in 242 B.C., with the establishment of Velina and Quirina, and no further additions were made. Hence, anyone who had Roman citizenship conferred on him after that time, wherever he lived, had to be enrolled in one of the existing tribes. No hard and fast rule seems to have been followed, and the tribe might be "urban" or "rustic", but some generalisations can be made; for example, citizens from Gallia Narbonensis tend to be enrolled in Voltinia, those from the eastern provinces in Collina or Quirina.
In inscriptions the name of the tribe normally appears between the filiation and the cognomen, thus:
= Quintus Lollius Urbicus, son of Marcus, of the tribe Quirina
