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.

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 various 

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

 Protozoa through Ctenophora," 1940:22-43.

THIRD EDITION 



The second edition of this list was so full of errors that it was never sent to the 

 general biological public. In the revision for this third edition the list of groups that 

 has "uniform" endings has been omitted. The following persons have furnished informa- 

 tion for the groups indicated : Invertebrata, Libbie H. Hyman and M. W. de Laubenfels ; 

 Protozoa, R. R. Kudo; Porifera, M. W. de Laubenfels; Platyhelminthes, Libbie H. 

 Hyman and H. W. Manter ; Cestoda, Robt. P. Dollfus; Nemertea, Libbie H. Hyman 

 and Arthur G. Humes ; Brachiopoda, Preston E. Cloud, Jr. ; Annelida, Olga Hartman and 

 Grace E. Pickford ; Crustacea, Fenner A. Chace, Jr. ; Arachnida, Alexander Petrun- 

 kevitch ; Acari, G. W. Wharton ; Pycnogonida, Joel W. Hedgpeth ; Myriapoda, Nelle B. 

 Causey; Insecta, F. M. Carpenter and Charles L. Remington; Mollusca, H. A. Rehder; 

 Tunicata, W. G. Van Name and A. G. Huntsman; Fishes, Carl H. Hubbs; Amphibia 

 and Reptilia, Grace L. Orton; Aves, Ernst Mayr and Alexander Wetmore. For trema- 

 todes Dawes (1946) "the Trematoda" has been followed, for fishes, amphibians, and rep- 

 tiles the classification in Romer's (1945) "Vertebrate Paleontology" has been used, and 

 for mammals that in Simpson's (1945) "The Principles of Classification and a Classifica- 

 tions of Mammals" has been followed.
