an ancient measure of corn, conjectured to be the same to our quarter, or eight bushels.

ACHERUSIA palus, a lake between Cumae and the promontory Mifenum, now il Lago Della Collucia, (Cluverius.) Some confound it with the Lacus Lucrinus, and others with the Lacus Avernus. But Strabo and Pliny distinguish them. The former takes it to be an effusion, exudation, or welches of the sea, and therefore called by Lycophron, ἀποβαίνων χύτης.—Also a lake of Epirus, through which the Acheron runs.—There is also an Acherusia, a peninsula of Bithynia on the Euxine, near Heraclea; and a cave there of the same name, through which Hercules is fabled to have descended to hell to drag forth Cerberus.
