In reviewing the CBCC Taxonomy Code and making revisions when they seemed appropriate, 

 various sources were consulted for the preferred taxonomic schemes on which to base the code symbols. 

 In certain groups, it has seemed advisable, for this publication, to alter the scheme of code symbols 

 from that set up earlier and used for CBCC coding. 



The Protozoa, Porifera, Cnidaria, Platyhelminthes, Acanthocephala, and Echinodermata have 

 been somewhat revised, largely in accordance with opinion expressed in the volumes issued to date of 

 The Invertebrates by Dr. Libbie H. Hyman . The classification of the Digenea (Platyhelminthes, 

 Trematoda)--that on which is based the scheme of code symbols --now follows closely that of Dr. George 

 LaRue , who was most kind in checking the Trematode list. For purposes of the present Code, this 

 scheme was projected by the CBCC to cover all Trematoda. The Cestoda and Turbellaria arrangements 

 are based largely on the schemes described in The Invertebrata, Volume III . In revising the list and 

 code symbols of Nematoda, Mrs. May Belle Chitwood of the Parasite Station at the USDA Experiment 

 Station, Beltsville, Maryland, has given valuable advice. 



For the Annelida, a number of references conveniently at hand were consulted, including 

 organizations indicated in Fresh-Water Invertebrates of the United States by T. W. Pennak 3 and 

 The Oligochaeta by J. Stephenson 4 , although older ("obsolete") names appearing in the list, included 

 for reference purposes, are derived from certain older texts. However, the scheme on which are based 

 the code symbols is the result of advice from Dr. Libbie Hyman (American Museum of Natural History, 

 New York, N. Y. ) and Dr. Marion Pettibone (University of New Hampshire). 



Other taxonomic groups, after being checked as far as possible at the CBCC, were submitted 

 during 1957 to authorities of the U. S. National Museum for review and criticism and for assistance in 

 filling in certain omissions. For the generosity of advice and time given by these persons, the CBCC 

 is most grateful.
