From the Pyrenees to the river Narbo the country is River Aude. The Tech and the Ruscino or Tet. flat; and through it flow the Illeberis and Ruscinus, past some cities of the same name inhabited by Celts. In this plain there are found what are called underground fish. A mistake of Timaeus as to the Rhone. The soil is light, and produces a quantity of grass called agrostis; and below this soil the earth is sandy for a depth of two or three cubits, through which the overflow of the river percolates; and with this water, as it makes its way, the fish also get below the soil to feed, for they are exceedingly fond of the root of the agrostis, and have thus made the whole plain full of subterranean fish, which people dig up and take. . . .

The Rhone has not five, but two mouths. . . .
