The eighth region, termed Gallia Cispadana, comprised the southern portion of Cisalpine Gaul, and was bounded on the north (as its name implied) by the river Padus or P0, from above Placentia to its mouth.
The ninth region comprised Liguria, extending along the seacoast from the Varus to the Macra, and inland as far as the river Padus, which constituted its northern boundary from its source in Mount Vesulus to its confluence with the Trebia just above Placentia.
The tenth region included Venetia from the Padus and Adriatic to the Alps, to which was annexed the neighboring peninsula of Istria, and to the west the territory of the Cenomani, a Gaulish tribe, extending from the Athesis to the Addua, which had previously been regarded as a part of Gallia Cisalpina.
The eleventh region, known as Gallia Transpadana, included all the rest of Cisalpine Gau1 from the Padus on the south and the Addua on the east to the foot of the Alps.
It was proposed that all the land north of the Padus (Po) lately in possession of the Cimbri, including that of the independent Celtic tribes which had been temporarily occupied by them, should be held available for distribution among the veterans of Marius.
