The Periplus would be great to pull information from for a description. I think Strabo mentions the names of the two capes on either side of the Bab el Mandeb too, but those are the types of things that would be great for a description.

As for the name of the Straits of Hormuz, we'd love to see any ancient references to it and its importance. We thought it was a strategic choke-point for trade and deserved a trade boost, but we just lack the information to put together a description for it.
