DOWNEY Smithsonian Institution SMITHSONIAN INSTITUTION PRESS WASHINGTON, D.C. 1968 Publications of the United States National Museum The scientific publications of the United States National Museum in- clude two series, Proceedings of the United States National Museum and United States National Museum Bulletin. In these series are published original articles and monographs dealing with the collections and work of the Museum and setting forth newly ac- quired facts in the field of anthropology, biology, geology, history, and technology. Copies of each publication are distributed to libraries and scientific organizations and to specialists and others interested in the various subjects. The Proceedings, begun in 1878, are intended for the publication, in separate form, of shorter papers. These are gathered in volumes, octavo in size, with the publication date of each paper recorded in the table of contents of the volume. In the Bulletin series, the first of which was issued in 1875, appear longer, separate publications consisting of monographs (occasionally in several parts) and volumes in which are collected works on related subjects. Bulletins are either octavo or quarto in size, depending on the needs of the presentation. Since 1902, papers relating to the bo- tanical collections of the Museum have been published in the Bulletin series under the heading Contributions from the United States National Herbarium. This work forms number 264 of the Bulletin series. Frank A. Taylor Director, United States National Museum U S GOVERNMENT PRINTING OFFICE WASHINGTON : 1968 iv Catalog of Recent Echinoid Type Specimens in the U.S. National Museum Smithsonian Institution and the | Museum of Comparative Zoology Harvard University By Maureen E. Downey Smithsonian Institution Thanks largely to the efforts of Austin H. Clark, late Curator of Echino- derms, the U.S. National Museum has one ofthe 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 Clark. 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 Fish 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: Name and author Reference with date Catalog number, locality, depth, date collected. Current name, if original name is nowasynonym, withareference, 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 Felland Dr. John Dearborn at the Museum of Comparative Zoology. Part of this work has been supported by a grant from the Smithsonian Research Foundation. Type Specimens of Echinoids Acanthocidaris hastigera A. Agassiz and H. L.

L. Clark clearly stated, in his original description in 1914, that this is not a species or subspecies, but at most a variety. Mortensen, in his Monograph, concurred in this opinion, even though he lists it as Echinarachnius parma obesa, as if it were a recognized sub- species. The USNM specimens have been removed from the type collec- tion and placed in the regular collection.
