tor in cases where no specialist could be found to furnish accurate information (birds, 

 fishes, etc.), the editor browsed through systematic works and found such information, 

 some of which later proved to be incorrect. For example, some references credited to 

 Lamarck by various writers are for vernacular names which should have no scientific 

 standing as scientific names. The following groups have been carefully corrected by 

 specialists and are believed to be reliable for authors and dates : Protozoa, Porifera, 

 Coelenterata (except Zoantharia), Platyhelminthes, Nemertea, Acanthocephala, Nematoda, 

 Bryozoa, Brachiopoda, Echinodermata, Annelida, Arachnida, Crustacea, Insecta, Tuni- 

 cata. Amphibia, Reptilia, and Mammalia ; other groups may not be.

PREFACE 



SECOND EDITION 



As there is continual demand for this list, which has been out of print for several 

 years, it seems desirable to publish a second edition. A few changes have been made 

 and the following persons made suggestions for the revision. A. H. Clark suggested 

 the term Hemizoa and other general changes. Grateful acknowledgment is made to 

 G. W. Wharton who corrected the proofs for the list. An excellent discussion of variou> 

 modern systems of classification will be found in Libbie H. Hyman's "The Invertebrates : 

 Protozoa through Ctenophora," 1940:22-43.
