The Echinoderms Newsletter! No. 5. January 1974 Prepared in the Department of invertebrate Zoology (Echinoderms) , National Museum of Natural History, Smithsonian Institution, Washington, D. C. 20560 U.S.A. Another year has suddenly disappeared. Again, we’re late. And again, we find that some of the information contained in this Newsletter is out-of- date . This issue, No. 5, represents some sort of anniversary, and we wonder where we should go from here, as far as the Newsletter itself is concerned. It seems evident that the Newsletter is useful to at least some of you, because we have received numerous enquiries concerning the whereabouts of this issue. As long as there is a continuing demand, we would be delighted to continue producing the Newsletter. We are somewhat concerned about its content; is there some way in which we can better serve echinoderm research? What should be added or subtracted? Should arguments/discussions concerning some important topics (classification of major taxa; phylogeny; conservation of echinoderms; "standard techniques"; etc.) be aired in these pages? Please let us have your views, and we'll circulate them. With the advent of the computer age (recently observed sweeping through the hallowed halls of the Smithsonian Institution) , we are now in a position to have our address labels produced by some automatic method , thereby saving a vast amount of time and trouble. We intend to distribute a revised Directory of Echinoderm Specialists with the next Newsletter. If your address has changed (or differs in some details from the address on your present mailing label) , please let us know by completing the form which comprises the last page of this Newsletter, and returning it to us. We hope to have the new Directory ready by around April, 1974. Happy New Year! David L. Pawson Maureen E. Downey ^The Echinoderms Newsletter is not intended to bepart of the scientific literature, and should not be cited, abstracted, or reprinted as a published document. 2 Zoological Record: Ailsa M. Clark writes "Thanks to everyone who sent me separates of their papers during my stint as Zoological Recorder for Echinoderms, now completed with the 1970 number. This work will be continued by the permanent staff of the Zoological Record (address: c/o British Museum (Natural History) , Cromwell Road, London SW7 , England) who work mainly from publications in the libraries. However, I'm sure they would appreciate receiving copies of any papers in obscure periodicals or such as might be subject to delay in reaching the British Museum Libraries". We should offer a great vote of thanks to Ailsa Clark for devoting so much of her time and energy to the Echinoderms section of the Zoological Record for so many years.- It will -be extremely difficult for future compilers to meet the high standards she has set. "THE PERIPROCT" - Alan BAKER and Helen CLARK are now producing an informal bulletin ( The Periproct ) of interest to echinoderm specialists whose research interests lie in the South Pacific. It is intended to be a rapid means of circulating echinoderm news and other information around the South Pacific area. Interested? Please contact Dr. Baker or Dr. Clark. Survey of British echinoderms: The Marine Biological Association of the U.K. and the Biological Records Center have begun a survey of British Echinoderms. Its main aim is to collect accurate information from which maps of distribution of echinoderm species can be drawn, and to add to knowledge of habits and habitats of each species. The survey will include those species known from depths of less than 200 meters, and a key to the 82 known species has already been prepared. The area covered includes the entire continental shelf to the north and west of the British Isles, the English Channel and the North Sea. While there is much already published information that can be used, additional information on distribution and ecology from researchers working with echinoderms or other marine animals, and amateur naturalists, particularly divers, is especially valuable. The Echinoderm Survey would welcome records from both professional and amateur biologists. Please write Dr. Eve C. Southward, (Echinoderm Survey), The Laboratory, Citadel Hill, Plymouth PL1 2PB, England for further information. 3 Workshop in X-Ray biocrystallography: From June 10-21, 1974, a workshop in X-Ray biocrystallography will be held at McGill University. The course will be given by Dr. Gabrielle Donnay, Professor of Crystallography, Department of Geological Sciences, McGill University, Station "A", P.O. Box 6070, Montreal, Quebec, Canada H3C 3G1. It will consist of an introduction to the theory and experimental methods of X-Ray crystallography, using single crystal techniques and powder methods. It should be useful to zoologists and paleontologists who have an interest in the nature of exo- and endo-skeletons. Cost of the course is $250.00. Rooms in student residences are available at $50.00 per week, including all meals. Applications are due by 15 April 1974. Please write Dr. Donnay for further details. CRAB WITH UMBRELLA Bob Foster writes "A group of geologists from Shell's Rijswijk, Holland, laboratory were studying recent carbonate sediments in the Persian Gulf from the motor vessel Tylos. One of the geologists. Gene Shinn, found a small crab carrying a living Echinodiscus auritus on its back. I saw it when he brought it back to Doha, Qatar. The crab had a carapace about 4 cm broad by 2 cm long. The two rear pairs of legs were rather small and terminated in small hooks. The legs faced. upward and it looked as though they could not have been turned around to touch the ground. The front two pairs of legs appeared normal, and there were two small equal sized claws. When found, the crab was carrying a 9 cm by 9 cm Echinodiscus right side up. When the echinoid was taken off, the crab would pick up again by wriggling underneath it. The crab held the echinoid by its edges, or more often just put the hooks into the spines. When the echinoid was taken away, the crab picked up a nearby shell. Gene took a short movie of the crab doing its act with the echinoid. If anyone is interested, his current address is: Mr. E. A. Shinn Public Affairs Department Shell Oil Company 15th Floor 1 Shell Plaza Houston, Texas 77001 U.S.A. 4 Acanthaster symposium: L. ELDREDGE has supplied the following information: A symposium "Biology and ecology of the crown-of -thorns starfish, Acanthaster plane i (L) " was held in Guam during May 1973 at the Pacific Science Association Second Inter- Congress. Fifteen papers have been brought together into a special symposium issue of the journal Micronesica (Volume 9, number 2, December, 1973). Single copies of the volume are available for $4.00 (postpaid) each from: Micronesica University of Guam P.0. Box EK Agana Guam 96910 U.S.A. International Symposium on Indo-Pacific Tropical Reef Biology: This symposium will be held on the Islands of Guam and Palau, Mariana and Caroline Islands Groups from June 23 - July 5, 1974, and will be followed by optional field excursions to Sulu Archipelago-Phi lippines and East Malaysia- Hong Kong. The symposium was arranged to determine the current status of knowledge of various groups of coral reef organisms, to discuss methods of closing gaps in our knowledge, and to discuss possible future programs of research. Group fare and accommodation programs are available. For further information, if seriously interested, please contact: Western Society of Naturalists David H.
