One of these is near its eastern extremity, and runs to the south-east, dividing the plain of Zerga from the great central level.

Like the main chain, it is of limestone; and, though low, has several remarkable peaks which serve as landmarks from a vast distance.
The Arabs call it Kebritiyeh, or "the Sulphur range," from a sulphurous spring which rises at its foot.

The other spur is thrown out near the western extremity, and runs towards the north-west, parallel to the course of the upper Khabour, which rises from its flank at Ras-el-Ain.
The name of Abd-el-aziz is applied to this spur, as well as to the continuation of the Sinjar between Arban and Halebi.

It is broken into innumerable valleys and ravines, abounding with wild animals, and is scantily wooded with dwarf oak.

Streams of water abound in it.
South of the Sinjar range, the country resumes the same level appearance which characterizes it between the Sinjar and the Mons Masius.
