Remarks. — Flabellum apertum was first reported ( Moseley 1881) from off Chile ( 48°S, Golfo de Penas) as F. patagonichum at 220 m. Cairns (1982) later reported two records from the continental slope off Isla Desolación ( 1262–1500 m). Specimens reported herein were also collected off Isla Desolación, off Islas Morton, and a northern range extension at 34°S. The species is thus known from 34° to 56°S off the Chilean coast at depths of 193–1500 m but is more widespread throughout the Subantarctic at similar depths ( Cairns 1982, 1995). It is well described and illustrated by Cairns (1982, 1995).
