NOTE: According to notes in Rosenberg, 2009, the online database Malacolog 4.1.1, H. antiquatus was described without a type locality. This same species was previously considered to occur in both the Eastern Pacific and the Western Atlantic, but some records of this species from the Western Atlantic may in fact be H. leptus instead.
