=Kolmanab= and =Einiwai= are two small but very conspicuous black hills eleven kilometres apart, rising from the sandy coast-plain between the Wadis Meisah and Di-ib. Both are surmounted by triangulation beacons, that on Kolmanab being in latitude 22° 32′ 26″, longitude 35° 53′ 36″, 137 metres above sea, and that on Einiwai being in latitude 22° 27′ 50″, longitude 35° 57′ 59″, 138 metres above sea. North-west of Kolmanab are some low banks called =Tinadei=, while about mid-way between Kolmanab and Einiwai is an isolated low hill called =Ankalidot=. =Osnei= is a small but conspicuous red granite hill, rising to 251 metres above sea, thirteen kilometres west-south-west from Einiwai. It contains a galt, which yields water for some little time after rain has fallen locally. =Ti Keferiai= is a conspicuous little isolated group of dark hills of no very great height, situated in the fork where the Wadis Didaut and Baueiwai join to form the Wad el Qireira. There are heavy accumulations of blown sand round the north-east flanks of the mass. The triangulation beacon on the summit has the position latitude 22° 21′ 0″, longitude 35° 49′ 47″, and is 494 metres above sea-level. Ti Keferiai forms a good landmark for the old mines of Romit, which are situated in some lower hills five kilometres south-west of the beacon. There are numerous excavations here in veins of smoky quartz with calcite and chalybite, which penetrate the country rock of highly crushed and decomposed diorite; a number of ancient grinding mills of diorite lie scattered about the place. Four kilometres north of Ti Keferiai, on the opposite side of Wadi Didaut, is a conspicuous hill of very red granite called =Adatalob Adara=, 385 metres above sea-level. Four kilometres further north-west is another hill, of nearly equal height, but of black aspect, called =Adatalob Hadal=. West of Ti Keferiai, at distances of five and a half and nine and a half kilometres respectively, are two conspicuous little hills rising from the plain, one on either side of the Wadi Didaut; these are called =Kikeiyet Sharqi= and =Kikeiyet Gharbi=. East of Ti Keferiai is a great sandy tract stretching to the Wadi Di-ib, from which low hills rise half swathed in blown sand; the principal hill groups bear the names of =Gebels Tishushi= and =Tishushi Tiboki=. =Qara Saba= is a high and steep hill mass of dark aspect, rising conspicuously to 788 metres above sea, between the Wadis Didaut and Baueiwai, some sixteen kilometres south-west of Ti Keferiai. The tract between Qara Saba and Ti Keferiai is a waste of blown sand through which low hills protrude in places.
