 The chief city of the Praetutii was Interamna, called for distinction's sake Interamna Praetutiana.They occupied a district of Picenum, bounded by the river Vomanus (modern Vomano) on the south and apparently by the stream called by Pliny the Albula on the north; but the Albula cannot be identified with certainty, and the text of Pliny may be corrupt as well as confused.He appears to place the Albula north of the Truentus (modern Tronto); but it is certain that the Praetutii did not extend as far to the north as the latter river, and it is probable that the stream now called the Salinello was their northern limit.
