 lan^'ufig-es ; {b) An Author Catalogue ; (c) A Subject Catalogue. 



The Schedules have been i-evised in accordance with the decisions 

 of tlie International Convention of 190.'). 



'1 he Subject Catalogue begins with some geuei-al sections 0000 to 0220, 

 It is then divided into Palaeozoology and Falaeobotany. Each of these 

 main divisions is sub-dividetl into three sections. The first section 

 gives the publications arranged according to strata; in the second 

 section the arrangement is according to fossils ; while the third section 

 gives a list of new genera and species. 



In each section the final arrangement of papers is in the 

 alphabetical order of authors' names. 



To find the papers dealing with a particular subject the reader

 The numbers given in the Index are llegistration numbers, and can 

 be used at once for turning to the propei- page of the Subject Index. 

 This is done by looking at the luimbers at the right-hand top corners 

 of the ]>ages. 



In the Author Catalogue the numbers placed within square brackets 

 at the end of each entiy are Registration numbers, and serve to 

 indicate the scope of each paper indexed. The meaning of these 

 numbers will at once be found by reference to the Schedule. 



In case the abbreviated titles of Journals are not understood, a key 

 to these is provided at the end of the volume. 



The literature indexed is mainly that of 1911, but includes 

 those portions of the literature of 1901-1910 in regard to which the 

 iudex slips were received by the Central Bureau too late for inclusion in 

 the previous volumes. There are also entries dated 1912. 



Topographical Symbols.

 the Topographical Classification. They are not used instead of 

 Registration numbers, but for sub-dividing the sections.
