No archaeological research has been done in the area and no other details are known. Vangaindrano is on the Mananara river but: there are two Mananara rivers in Madagascar; this is the southern one. On the mouth of the northern one archaeological research has been done.

The Arabic term kaws has the general meaning of “headwind” and in the Indian Ocean, pronounced kis, means the southwest monsoon; at Madagascar, kosy is the name of the southern breeze. The toponymy, “Port-Kous” is used frequently. As for Kuri and Haduda, Ibn Majid cites two on the eastern side, one by Big Dipper four fingers high and the other, much further south, is one finger only. Khoury places the first in Mananjary and the second in Faux Cap. Tibbetts who reads Kaws does not speak of the first and would see, in the second, the old Turubaya (= Fort Dauphin). Centered on Reunion, a full cape starts exactly from Mananjary which is at the same latitude and it may very well be that this bandar Kus is this place; but it should be noted that throughout all the writings of Ibn Majid and those of his disciple Sulayman al-Mahri there reigns a constant confusion between the two toponyms bandar Kus and bandar Kuri, confusion attributable not to these authors but to their informants, without exclude any spelling errors due to later copyists. It emerges nevertheless from the texts that a bandar Kuri was the southernmost anchorage to the west of Cape Sainte Marie and that a bandar Kis was roughly its counterpart to the east; however, the Antandroy coast has no natural harbor and has long been a cemetery for European ships; also, it is necessary to suppose these two places further north on one side and the other on the other side.

Note: the reason why other authors than me put Bandar Kus and Maqarah way further north is a different solution to the mistake in Ibn Majid’s Madagascar map. When working with the exact length of a finger Madagascar becomes way longer than the real one. So, I deleted the last two places on each site of the island as their names are clearly duplicates. But another solution is to make the length of the fingers for Nach smaller and so fit all places on the island. I do not think that the medieval pilots would be making such big mistakes and also the corresponding places on the East African coast are correct. That is Mozambique island and Sofala who are known places.
