a division of the province of Tobolsk in Siberia. It is bounded on the north by the straits of Weigatza, on the east by a large bay of the frozen ocean which runs into the land towards the south, and at the 65th degree of latitude separates into two arms; one of which is called the Obkaia Guba, or Oby-bay; and the other Tazowkaia Guba, or the bay of Tazow. The river Oby empties itself into the former, and the Taz into the latter. This district was under the Russian dominion long before the other parts of Siberia were conquered, being reduced by the Czar Gabriel so early as the year 1530.
