7. LAMBERT <strong>and</strong> THIERY in <strong>the</strong>ir" Essai de nomenclature raisonnee des Echinides,<br />
fasc. 1-9, 1909-1925) enumerated a large number of genera <strong>and</strong> species known to <strong>the</strong><br />
science at that time, <strong>and</strong> reviewed (sometimes revised) genera <strong>and</strong> even species, but<br />
at <strong>the</strong> same time <strong>the</strong>y changed a number of <strong>the</strong> old familiar names to those that are<br />
not acceptable by many authors. The fossil species <strong>from</strong> Japan <strong>and</strong> <strong>the</strong> <strong>adjacent</strong><br />
