ACHI′ROE (Achiroê), or according to Apollodorus (ii. 1. § 4) Anchinoë, which is perhaps a mistake for Anchiroë, was a daughter of Nilus, and the wife of Belus, by whom she became the mother of Aegyptus and Danaus.

Pseudo-Apollodorus, Bibliotheca 2. 11 (trans. Aldrich) (Greek mythographer C2nd A.D.) :
"Belos remained to become king of Aigyptos (Egypt), and married Neilos' (the River Nile's) daughter Ankhinoe, who gave him twin sons, Aigyptos and Danaus, to whom Euripides [tragedian C5th B.C.] adds Kepheus (Cepheus) and Phineus."
