The river's name can only be inferred from the name "Margvm Fl." attached to the route stretch immediately above its middle course. In this instance the inference would be correct (compare note under river #60). There is no knowing whether the mapmaker specifically intended users to make the inference, with the result that he consciously omits to name the river otherwise, even though there is space to do so.
