Diur
Διούρ
Diur (Διούρ), the name given by Ptolemy (4.1 § 12) to one of the branch chains of the Atlas system of mountains, in Mauretania Tingitana; it appears to be the range which runs NW. from about the sources of the river Malva to the Straits. Ptolemy (4.1.3) mentions a river of the same name, having its mouth close to Mons Solis, probably the Wad-el-Gored.
