Catalog number, locality, depth, date collected. Current name, if 

 original name is now a synonym, with a reference, usually to Mortensen's 

 Monograph of the Echinoidea, as this is the latest monographic work 

 giving complete synonymy. 



Remarks 



The abbreviations USNM and MCZ before the catalog numbers indicate that 

 the specimens are located at the U.S. National Museum or the Museum of 

 Comparative Zoology, respectively. 



An index to all the names, generic and specific, original and current, 

 is included. It is hoped that this catalog will prove useful to echinoid 

 workers, as well as to students in the field of echinology. 



I wish to express my sincere appreciation for help and advice during 

 the preparation of this catalog to Dr. David L. Pawson, Dr. Frank J. 

 Maturo, Dr. Fenner A. Chace, and others at the U.S. National Museum, 

 and to Professor H. Barraclough Fell and Dr. John Dearborn at the Museum 

 of Comparative Zoology. 



Part of this work has been supported by a grant from the Smithsonian 

 Research Foundation.
