The arrangement of the catalog is alphabetical, according to the original 

 name of the genus or species. Types are listed as follows: 



Name and author 



Reference with date 



Current name, if original name is now a synonym. Catalog number, 

 locality, depth, date collected. 



Remarks 



The abbreviations used before the catalog numbers areas follows: 



USNM U.S. National Museum 



MCZ Museum of Comparative Zoology at Harvard 



YPM Yale Peabody Museum 



AHF Allan Hancock Foundation 



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

 appended. It is hoped that this catalog will prove useful to ophiuroid 

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



I wish to acknowledge my indebtedness for help and advice during the 

 preparation of this catalog to Dr. David L. Pawson, U.S. National Museum; 

 Professor H. B. Fell and Dr. Richard Chesher, Museum of Comparative 

 Zoology; Dr. Willard Hartman, Yale Peabody Museum; and Dr. John Garth, 

 Allan Hancock Foundation. Special thanks are due to Capt. Fred 

 Ziesenhenne, who located and examined type material at the Allan Hancock 

 Foundation which I could not find during my visit there. 



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

 Research Foundation.
