The ijjEcjhinoderms Newsletter Mo. 6. April, 1975. Prepared in the Department of Invertebrate Zoology (Echinoderms), National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560 U.S.A. In the last newsletter we solicited your comments concerning the future of the newsletter, and asked you to suggest changes, additions, deletion etc. We found that those who responded to this request noted that the Newsletter was useful essentially in its present form, and should be continued* We were encouraged to issue it on a more regular basis. We have not included a revised address list with this issue; we plan to do so during August or September, if all goes well. We now have an automatically printed labeling system, so that should save a considerable amount of time. We would like to propose at the Echinoderms Conference in Rovinj , Yugoslavia that somebody else take over production of the newsletter. One or two people have volunteered to assist with this, and we would like to encourage others to do so. Our other commitments invariably result in delays in preparation and printing, and somehow we never get around to issuing it on time. Certainly it is a matter to be discussed seriously in Yugoslavia. David L. Pawson Maureen E* Downey ^Thc Echinoderms Newsletter is not intended to be part of the scientific literature, and should not be cited, abstracted* or reprinted as a published document t SUGGESTIONS AND REQUESTS A.N. BAKER would like to learn of any spare volumes of Mortensen*s monograph of the echinoids. I. FERBER would like to have information on irregular echinoids (particularly Spatangoida) observed in situ : distribution, habitats, burrowing behavior, depth and rate of burrowing, sediment type, population density, size. data, etc. She would also like to have references to unpublished studies on biology and ecology of irregular sea urchins J. D. GREEN would like to hear from those who arc working on holothurian systematics, reproductive biology add ultras tructurc, especially other graduate students whose work has not yet appeared in the literature. H.K. HESS is looking for a slab with several specimens of Uintacrinus socialis (as complete as possible) and offers in exchange either slabs with Chariocrinus andreac or Pentacrinites dargnicsi (Middle Jurassic crinoids) or specimen (s) of Pelanodiadcma oplithicum (complete, with lantern), a Middle Jurassic cchinothurioid. F.H.C. HOTCHKISS would like to receive alcohol preserved starfish with more or fewer arms than normal, for dissection and study. He is also interested in obtaining scries of the genus Astropecten as comparative material for a revision of the genus. A. J. JORDAN would like to examine scanning electron micrographs of echinoid plates, both surface and broken edge views. P.M. KIER would like to study Triassic echinoids from anywhere in the world. C. KROPACH requests information on Indian Ocean cchinodcrms, Acanthaster planci studies and status world -wide. J. S. LUCAS would like to know of any data on, or references to, hybridization in asteroids (apart from Gemmill, 1912). S.S. MACZYNSKA would like to have specimens of any species of holasteroid from the Cretaceous. K. MARKEL would like to study lanterns of echinothuriid echinoids. A. MIRONOV would like to study recent sea urchins of the suborder Mcridostcrnina from anywhere in the world. C. OGURO would like to receive preserved specimens of asteroids (especially Luidiidac, Astropcctinidac and Asteriidac) for comparative anatomy and systematic study. Exchange of specimens will be welcomed. C. R.C. PAUL would like to have records or soecimens of Ordovician cchinodcrm fragments (particularly cup plates) from anywhere in the world, but especially South America, for work on Ordovician faunal provinces. D. L. PAWSON would like to contact anybody who has information on swimming activities of holothurians , beyond that which has appeared in the published literature. F.W.E. ROWE would like to receive information and the loan of specimens of the asteroid genera Nardoa, Gomophia and Asterodiscus . He would also like to have records of Tasmanian echinodcrms from other institutions. He has tentatively proposed that a symposium on echinodcrms be held in Sydney, Australia around January -February 1977. Y. SCHLESINGER would like to have information on dense populations of holothurians, their sexual behavior, spawning, larval development, as well as on occurrence of holothurians near ports and the effect of phosphate^ upon them. P.H. SIEGEL would like to have references and/or reprints of papers covering any aspect of the biology and distribution of the holothurian Chiridota laevis i n, particular , and chiridotid holothurians in general . H.L . STRIMPLE would like answers to the following questions concerning ontogeny of modern comatulid crinoids: 1. In the "cystid” stage, do the orals remain open all of time or do they withdraw their podia or tentacles and close their orals on occasion? 2. What is the position of the anus and the rectum in the "cystid” stage. 3. Is there a hydroporc penetrating the posterior oral and connected to a stone canal in the "cystid” stage? He thinks not, but needs to ask to be certain. TASMANIAN MUSEUM, G.P.O. Box 1164M, Hobart 7001, Tasmania, Australia, would like to purchase a copy of H.L. Clark's (1946) paper "The cchinoderm fauna 7 of Australia”. Please contact Miss Alison Green, Curator of Invertebrate Zoology at the Tasmanian Museum if you have a spare copy of the paper.
