SYNONYMIC INDEXICAL LIST OF THE FOSSILS OF 

 MISSOURI. 



BY CHARLES R. KEYE8. 



In the preparation of an index to the fossils of Missouri, 

 it is the intention to put in form for ready reference a compact 

 list of not only the valid species which have been found within 

 the limits of the State, but also a list of the different names 

 which have been, at various times, proposed for forms which 

 are now known to belong to species previously described. In 

 this way, all the fossils which have been reported from the 

 region, no matter what name or names may have been assumed, 

 may be referred to without difficulty under their proper titles. 

 At the same time, the page is given where each species is con- 

 sidered in the report on the Paleontology of Missouri, where 

 also additional references are given for an exhaustive study of 

 the particular forms. The index, therefore, may be regarded 

 as a systematic arrangement of all the terms which have been 

 applied to the fossils occurring in Missouri. At the same time, 

 it serves as a check-list fo? cataloguing purposes.
