TA´RSIUS(Τάρσιος), a river of Mysia in the neighbourhood of the town of Zeleia, which had its source in Mount Temnus, and flowed in a northeastern direction through the lake of Miletopolis, and, issuing from it, continued its north-eastern course till it joined the Macestus. (Strab. xiii. p. p. 587.) Strabo indeed states that the river flowed in numerous windings not far from Zeleia; but he can scarcely mean any other river than the one now bearing the name Balikesri, and which the Turks still call Tarza. Hamilton ( Researches, vol. 2. p. 106) identifies it with the Kara Suor Kara Dere Su, which flows into Lake Maniyas.
