Huntingford dismisses the first two as being too close to Zanzibar and Pemba islands (which he identifies with Menouthis, and follows the author of the Periplus in locating Menouthis north of Rhapta). He observes that there is no river at Msasani, and thus concludes Kisuyu or the Rufiji delta are the most likely candidates. However, J. Innes Miller points out that Roman coins have been found on Pemba; that the Ruvu emerges near the Kilimanjaro and Meru mountains—which confirm the account of Diogenes; and that an old inscription in Semitic characters has been found near the Pangani estuary, which make Pemba a likely candidate for Rhapta.[citation needed][verification needed] However, the first evidence of inhabitation starts solely in the seventh century at a site called Tumbe on the northern end of the island,[7] limpidly contradicting these assertions.
