Thanks largely to the efforts of Austin H. Clark, late Curator of Echino- 

 derms, the U.S. National Museum has one of the major echinoderm collec- 

 tions in the world. The large and comprehensive collection at the Museum 

 of Comparative Zoology at Harvard achieved its importance mainly 

 through the diligence of Alexander Agassiz and Hubert Lyman Clarke 

 The U.S. Fish Commission deserves the principal credit for the size and 

 scope of these two collections, as many of the specimens in both institutions 

 were collected by the Albatross, Blake, Fish Hawk, and other Rsh Com- 

 mission vessels. The particularly rich fauna of the Pacific yielded many 

 new species, especially from the areas of the Philippine and Hawaiian 

 Islands. 



The cataloged echinoid type specimens in the U.S. National Museum com- 

 prise 479 lots (about 1,400 specimens), representing 134 nominal species 

 and subspecies of 79 nominal genera. The Museum of Comparative Zoology 

 has 470 cataloged lots of echinoid type specimens, representing 170 nomi- 

 nal species and subspecies of 136 nominal genera. More than half of the 

 specimens in both collections consist of dry material; the rest are pre- 

 served in alcohol. 



The author has examined and verified every type specimen herein listed. 

 In many cases a holotype was not designated in the original description 

 of a species, and unless the species was based on a single specimen, the 

 material on which the description was based is treated as syntypic, even 

 though one specimen was labeled " holotype. " Types subsequently desig- 

 nated, either by the same author or another, are lectotypes. Paratypes are 

 specimens, other than the designated holotype, mentioned in the original 

 publication or material other than the holotype on which the original 

 description was based. Only primary type material is included here; and 

 only types having nomenclatural significance are listed. 



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

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