DISTRIBUTION.—This species was known only from the two type-specimens described by Loman from “Masatierra,” now called Isla Robinson Crusoe, the major island of the Juan Fernandez group. His specimens came from 30–45 meters and the many specimens listed above maintain the endemic character of A. fernandeziana while extending its known depth to 10–180 meters.
