=Gebel Muelih= is a great boss of white granite situated close to the north side of Wadi Muelih in longitude 34°. Its summit, marked by a beacon, in latitude 24° 52′ 44″, longitude 34° 0′ 37″, is 707 metres above sea and 350 metres above the wadi which courses round its south flank, and from which it is easily climbed. The upper view on Plate XI gives an idea of its appearance as seen from the base line camp in the wadi six kilometres east of it. =Gebel Hagar Dungash= is a great mass of high hills situated north of Gebel Muelih. The beacon on its highest point, in latitude 24° 59′ 12″, longitude 34° 2′ 33″, is 815 metres above sea-level. In the hills which flank the main mass are numerous sharp peaks, one of the most conspicuous of which, eight and a half kilometres south-west of the beacon, is called =Gebel Um Dalalil=. A ridge five kilometres due east of the beacon bears the name of =Erf Rod Um Rashid=. The rocks of Haggar Dungash are chiefly dark schists. PLATE X.

[Illustration: View in Wadi Muelih (Base-line Camp).

Its highest peak is 849 metres above the sea. It is drained southwards by the Wadi Muelih. =Gebel Hamrat Wogud=, which is likewise of granite, is a higher mountain mass fifteen kilometres east of Iteima. Its highest point, marked by a beacon, is in latitude 25° 9′ 34″, longitude 34° 20′ 0″, and 1,103 metres above sea. It is drained southwards by the Rod Um el Farag, a tributary of Wadi Gerf. Between Gebels Muelih and Mudergeg is a sandy plain with low hills, the more conspicuous of which bear special names; among them are =Marwot Rod el Ligah=, =Erf Sagur=, and =Khusa el Faraon=, the last-named being a group of small but very remarkable black hills eleven kilometres due south of Erf el Fahid. Marwot Rod el Ligah is a triangulation point; its beacon is 514 metres above sea-level. =Gebel Sukari= is a very craggy high ridge of granitic rock twenty-two kilometres north of Gebel Zabara. Its highest point, which is at its north end, is 630 metres above sea-level, but the triangulation beacon was erected on a lower part of the ridge further south, in latitude 24° 56′ 50″, longitude 34° 42′ 50″, at an altitude of 476 metres, in order to be near to the extensive old mines and ruins which exist in the locality. Gebel Sukari is drained by various feeders of Wadi Sukari.
