«Chlamys (Chlamys) pseudislandica arconis MacNeil, n. subsp.
Plate 23, figures 7, 8 Discussion.— This subspecies differs from typical C. pseudislandica by its finer ribs, of which only a few have any tendency to divide, and by its longer ear and broader byssal notch. Since only one specimen like this has been seen, it may be no more than an extreme variant of C. pseudislandica. This specimen, dredged from a depth of 300 feet, was alive when taken.
Holotype: The holotype (CAS 12747) measures 71 mm in height and 66.5 mm in length; the double convexity is 30 mm. Type locality: Arctic Ocean about 17 miles west of Arcon Beach, 71°21'30" N.. 157°23'00" W., CAS 34347.» FRANCIS STEARNS MACNEIL, 1967
