And on the sea lies the Asiatic side of the Bosporus, or the Syndic territory. After this latter, one comes to the Achaei and the Zygii and the Heniochi, and also the Cercetae and the Macropogones. And above these are situated the narrow passes of the Phtheirophagi (Phthirophagi); and after the Heniochi the Colchian country, which lies at the foot of the Caucasian, or Moschian, Mountains.
