SIGA(Σίγα, Ptol. iv.2.2), a commercial town of Mauritania Caesariensis, seated near the mouth of a river of the same name in a large bay. The mouth of the river formed the port of the city, at a distance of 3 miles from it (Sigensis Portus, ltin. Ant. p. 13), opposite to the island of Acra, on the highroad, and near Cirta, the residence of Syphax. (Strab. 17. p. 829; Plin. Nat. 5.2. s. 1.) In Strabo's time it was in ruins, but must have been subsequently restored, since it is mentioned in the Itinerary (p. 12) as a Roman municipium. (Comp. Ptol. l. c.;Mela, 1.5; Scylax, 51, 52.) According to Shaw ( Travels, p. 12), who, however, did not visit the place, its ruins are still to be seen by the present Tacumbrit;others identify it with the Areschkulof the Arabs, at the mouth of the Tafna, near Rasgun.
