MASSI´THOLUS(Μασσίθολος), a river of Libya, the source of which Ptolemy (Ptol. 4.6.8), places in the mountain called Theon Ochema, and its embouchure(§ 9) in the Hesperian bay, between Hesperium Ceras and the Hypodromus of Aethiopia, in E. long. 14° 30‘, N. lat. 6° 20‘. It has been identified with the Gambia, which can be no other than the ancient Stachir or Trachir; one of the rivers which flow into the Atlantic, between the Kamarancaand the Mesurado, is the probable representative of the Massitholus.
