, a small volcanic island in the Red Sea in 17° 52′ N. Lat., called Kotumble on the English Admiralty charts. The island has a rich flora, which has been studied by the botanist Ehrenberg, and is noteworthy for its iron deposits, which are mentioned as early as the geographer Ibn al-Mud̲j̲āwir (d. 630 a. h.).
