Britanni
Eth. Britanni Pliny (4.17) places Britanni on the Gallic coast, between a people who belong to the pagus of Gesoriacum (Boulogne) and the Ambiani. They would, therefore, be about the river Canche. Whether this is a blunder of Pliny, or a corruption in his text, or whether there were Britanni on this coast, we have no means of determining.
