Antigone is a genus of large birds in the crane family Gruidae. The species in this genus were formerly placed in the genus Grus.
The specific epithet is based on the Greek mythology:  Antigone was the daughter of the Trojan king Laomedon. 
The author appears to have confused this myth with that of Gerana, queen of the pigmies, who considered herself more beautiful than Hera and was turned into a crane.
