In A Dictionary of Scripture Geography (published 1846), John Miles describes Upper and Lower Kurdistan as following:
Modern Curdistan is of much greater extent than the ancient Assyria, and is composed of two parts the Upper and Lower.
In the former is the province of Ardelan, the ancient Arropachatis, now nominally a part of Irak Ajami, and belonging to the north west division called Al Jobal.
It contains five others namely, Betlis, the ancient Carduchia, lying to the south and south west of the lake Van.
East and south east of Betlis is the principality of Julamerick, south west of it is the principality of Amadia.
the fourth is Jeezera ul Omar, a city on an island in the Tigris, and corresponding to the ancient Bezabde.
the fifth and largest is Kara Djiolan, with a capital of the same name.
The pashalics of Kirkook and Solimania also comprise part of Upper Curdistan.
Lower Curdistan comprises all the level tract to the east of the Tigris, and the minor ranges immediately bounding the plains and reaching thence to the foot of the great range, which may justly be denominated the Alps of western Asia.

The northern, northwestern and northeastern parts of Kurdistan are referred to as upper Kurdistan, and includes the areas from west of Amed to Lake Urmia.

The lowlands of southern Kurdistan are called lower Kurdistan.
The main cities in this area are Kirkuk and Arbil.
