Organization of 'The Wean (Bibliography 



The bibliography consists of five parts: 

 Systematic Index 

 Subject Index 

 Geographic Index 

 Author Index 

 Bibliography 



Each of the numbers 800001 to 803501 refers to an article, book, or report listed numer- 

 ically in the final section, the Bibliography. 



Systematic Index: Thirteen major categories have been adopted, and they have been 

 arranged in the following sequence: 



Agnatha 



Acanthodii 



Antiarchi 



Arthrodira 



Bradyodonti 



Holocephali 



Elasmobranchii 



Dipnoi 



Rhipidistia 



Coelacanthini 



Chondrostei 



Holostei 



Teleostei 



Each of these main groups has been divided into categories equivalent to superorders 

 (with the suffix -omorpha uniformly applied) , unless the number of included genera is 

 too small to make subdivision advantageous. Subdivision to orders (with the suffix 

 -iformes uniformly applied) , in some cases to suborders (with the suffix -oidei) , and then 

 to families (with the suffix -idae) was made according to the same principle of economy. 

 Except for the 13 major groups, the names in all categories are listed alphabetically. The 

 alphabetical arrangement of a limited number of higher categories was adopted to avoid 

 unnecessary commitments to any particular phylogenetic scheme. Where controversy 

 exists about the status of a group or name, the group or name chosen was the one that 

 seemed to be better established and in more widespread use, or more likely to have long- 

 range stability. We believe that the 566 names adopted will be immediately recognizable 

 by all systematic researchers working with the animals concerned. 



Subject Index: Nine major subdivisions have been arranged as follows: 

 Systematics and Nomenclature 

 Structure and Function (of organ systems) 

 Ontogeny 

 Evolution 



Ichthyological Techniques 

 Ecology
