3. A son of Ptolemy Soter and Eurydice, daughter of Antipater, succeeded his brother Ptolemy Ceraunus on the throne of Macedonia, after the latter had fallen in battle against the Gauls (B. C. 280); but was compelled by the Macedonian troops to resign the crown, after a reign of only two months. (Euseb. Arm. pp. 156, 157; Dexippus, apud Syncell. pp. 267, 270.) His reign is omitted by Justin.
