Unidentified pearlfish.

Jordan (1921) noted that a pearlfish identified as Fierasfer dubius Putnam, 1874, was collected “ 150 miles southwest of Point Loma,” southern California, placing the collection off northern Baja California. Fierasfer dubius, now Carapus dubius (Putnam, 1874), is known from the Pacific coast of southern Baja California (23°33.6’N, 110°21.5’W) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Jordan described the specimen as “encrusted in mother of pearl” (as occasionally happens to the commensal pearlfishes), which would have made identification to species problematic.
