OFFICIAL LISTS AND INDEXES 



INTRODUCTORY NOTE 



The International Commission on Zoological Nomenclature was founded in Leiden in 1 895 during the 3rd International 

 Congress of Zoology . It is devoted entirely to providing a service for the zoological and palaeontological community and 

 has the task of stabilising and promoting uniformity in the nomenclature of animals without interfering with taxonomic 

 freedom. To this end, the Commission publishes the International Code of Zoological Nomenclature, the 3rd Edition of 

 which appeared in 1985 and contains the definitive rules for the application of zoological names. The Commission is 

 empowered to suspend the rules when their strict application would cause confusion or would act against stability or 

 universality in nomenclature, but only after consultation with interested zoologists through the Bulletin of Zoological 

 Nomenclature, in which such problems are discussed before the Commission reaches a final decision by means of a vote. 

 The Commission's rulings are published in the Bulletin in the form of Opinions or, when completion or correction of an 

 earlier Opinion is involved, Directions. 



Names and titles of works upon which the Commission has ruled are placed on the Commission's Official Lists or Official 

 Indexes. These cover family-group names, generic names, specific names and the titles of works. 



In 1958 and 1966, the International Trust for Zoological Nomenclature, which acts on behalf of the Commission as its funding 

 and publishing body, published instalments of the Official Lists and Indexes in a number of separate parts. The present volume 

 incorporates all the names and titles of works included in these earlier instalments and those added up to the end of volume 

 42 (December 1985) of the Bulletin of Zoological Nomenclature. Entries total about 9,900, of which 134 are the titles of 

 works. 



Names are listed in alphabetical order. Homonyms are listed in alphabetical order by author, this being the arrangement 

 likely to be most helpful to the majority of users of this volume. Those who would have preferred homonyms to be listed 

 chronologically will have little difficulty in following the present arrangement. 



Names have been placed on the Official Lists and Indexes over a span of many years and the varied wording of the entries 

 reflects differing practices on the part of the Commission. Similarly, abbreviations of references are not in all cases consistent. 



Each entry for a name or a title of a work includes the number of the Opinion or Direction under which it was placed on an 

 Official List or Index. Publications containing most Opinions and Directions and the detailed history of each case are still 

 in print and can be obtained from The International Trust for Zoological Nomenclature, c/o British Museum (Natural 

 History), Cromwell Road, London SW7 5BD, U.K. 



The names and titles of works are listed in four sections: 

 Section I: Family-group names placed on the Official List and Index. 

 Section II: Generic names placed on the Official List and Index. 

 Section III: Specific names placed on the Official List and Index. 

 Section IV 



Part I: Titles of works placed on the Official List. 



Part II: Titles of works placed on the Official Index. 



Following the sections giving the names and the titles of works is a systematic index of all names on the Official Lists followed 

 by a list of bibliographic references to the Directions and Opinions under which names and titles of works have been placed 

 on the Official Lists and Indexes. 



It is inevitable that a compilation of this kind will contain a number of errors. The Trust would welcome notification of 

 corrections for incorporation in any subsequent edition of the Official Lists and Indexes. 



This volume has been edited by R. V. Melville (Secretary to the International Commission on Zoological Nomenclature 

 from 1968 to 1985) and J. D. D. Smith (Scientific Administrator to the Commission) with assistance from the other members 

 of the Commission's Secretariat: P. K. Tubbs (Executive Secretary), M. E. Tollitt (Zoologist) and N. A. Erridge (Assistant 

 Zoologist).
