Bibliographic references and adequate descriptions of most of 

 these species are given in the two papers of Mr. Hayward, referred 

 to at the beginning of this work, but I have not always followed 

 the synonymy given by that author and only the original localities 

 are cited above in most cases, because of the composite nature of 

 the material associated by Mr. Hayward under his conception of 

 specific scope.
