The Echinoderms Newsletter 1 No. 8. February, 1977 Prepared in the Department of Invertebrate Zoology (Echinoderms), National Museum of Natural History, Smithsonian Institution, Washington D.C. , 20560, U.S.A. With this issue we include the good news that the Third Echino- derms Conference is to be held in March, 197^. Those of you who are interested in participating are urged to complete and send to Frank Howe the enclosed pre-registration form without delay. Regional Editors, we eagerly await your contributions; please send us what you have, and we’ll circulate it promptly. I think that for the first time ever we have produced two News- letters within the span of a year. This astounding feat would not have been possible at all without the monumental labors of Cynthia Gust who, becoming impatient with our well developed procrastination techniques, set to and typed virtually all of the Newsletter, duplicated it, addressed the envelopes, and did a million other things. We owe her a great vote of thanks. David L. Pawson Maureen E. Downey ■^The Echinoderms Newsletter is not intended to be part of the scientific literature, and should not be cited, abstracted, or reprinted as published document. HELP!! - ADDRESSES UNKNOWN If you happen to know the addresses of any of the following people, please let us know. Thank you. J. Campbell Judith Eastwood Finn Edvardsen Losza Endelman Carol Mosher Fernandez Olga Grageda Spencer Hamada J.R. Harger Ira Jones Michael Kyte Landenberger Paul Leviten Karl Mauzey R*G. McKellar R.F. McPherson Richard Merrill A. T. Mu P.B. Noble B. S. Vasu Kathleen Woolley REGIONAL EDITORS . we are ready to receive reports from the numerous Regional Editors that were listed in the last Newsletter. Please send as any information you have, and we'U include it in Newsletter No 9 Thank you. J Additions to Regional Editors: Sigmund Kardas - Spain and Canary Islands. Jorge A. Petersen - Brazil ( "Recent Publications" list : We are thinking of making the "Recent Publications" list more useful by adding a brief abstract for each title (where appropriate). In order to provide this service we would have to depend upon you to provide us with reprints or, in the case of papers in press, a very brief summary of the paper. We think that the list of titles would be much more useful than it is now if abseracts were to be included. J&mes Hall Paleontological Society : Interested persons are invite4 to join the James Hall Paleontological Society of New York State, a non- profit organization being founded by collectors of New York State fossils to further science and to share experiences. Please contact F. H.C. Hotchkiss for further information. Reviews of books and papers : Several correspondents have suggested that the Newsletter might include reviews of books and important papers, especially those published in obscure journals. We'll do it, provided reviews are not libelous. Information on collections of echinoderms : E. Tortonese has suggested that we might collect information on systematic collections of echinoderms (size, availability, types, etc). Certainly, it would be good to know where all existing type -specimens of echinoderms are currently being held around the world. Along these lines, what kinds of information on collections would you like to have available? Please write to us with your suggestions, and we will try to get something started. At the very least, for example, it would be good to have a lisl/of the published catalogues of type -specimens of echinoderms. Theses and Dissertations Addendum to the lists of Ph. D. Dissertations and Masters* Theses concerning echinoderms. Previous lists publishe in the Newsletter: no. 3 (April 1971); No. 4 (December 1972); No. 6 (April 1975); No. 7 (July 1976).
