Feature type: river
Segment grid: 4C3
The form of the name is hard to determine in its entirety. A vertical crack bisects the opening letter ("B" ?). The fourth letter ("r" ?) remains very uncertain, and it is not clear whether three letters, or two, then follow before the final "da".
The river course became irrecoverable once a copyist evidently omitted to draw it. Placement of the name in open water beyond the river mouth is a puzzle, because to fit it in hereabouts on land would not seem difficult, even had that been impossible at the source (wherever the mapmaker had located it; if there was once a mountain range to serve the purpose, it, too, has dropped out).
