Name: Petra

Feature type: name, no symbol

Segment grid: 9B1

After Petra, the route curves up and the mapmaker has two stretches to fit in before the junction at Salaberina, although only space for one name and distance figure. Having begun the first name (Comitanasso), he therefore then makes it slope away and above the second name. Route linework follows only under the second name (Vbinnaca). Even though the space is available, there is no attempt here to repeat the expedient of a reverse turn used for the approach to Sinope from Thomia and Syrtad above (9A1).
