It is, I hope, never too late to acknowledge a mistake and correct a blunder. Since the appearance of my note on the Castle of Abrīḳ (see J.R.A.S. for October, 1895, p. 739), Professor De Goeje has called my attention to a passage in the “Tanbih” of Mas'ūdi, which negatives the identification of Abrīḳ with the modern Arabkir, and proves incontrovertibly that Tephrikē, of which there can be little doubt that Divrigi (or Divrik) is the present representative, must be the place which various Arab geographers describe under the name aforesaid of Abrīḳ or Abrūḳ.
