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 />
