figures are marked by an asterisk ; and in the case of fossil species 

 which are not recorded in the text of this Catalogue a reference is

 descriptions and figures of some of the American forms are required 

 before their right to specific distinction can be regarded as certain, 

 or their proper position in the series as finally determined.
