The numerical symbol to be used for Paleeontological books 

 and papers is obtained by a combination of the Geological 

 stratigraphical number (two figures), with a number (four figures) 

 representing the subdivision of the animal or vegetable kingdom 

 to which the fossil forms described belong. Thus a paper on 

 Triassic Cephalopoda will have the symbol K 65.2231, one on 

 Carboniferous ferns will be numbered K 55.6700. 



The numbers for Zoological sub-divisions are identical with 

 those used in i he Zoological schedule. The numbers for Botanical 

 sub-divisions are identical with those used in the Botanical 

 schedule. 



The alphabetical symbols for Topography can be added, if 

 necessary. In this case a paper on Cretaceous Fishes from 

 Asiatic Turkey would bear the symbol K 75.5431 ei.
