Echinoidea Clypeasteroidea
Biodiversity Journal, 2014, 5 (2): 291–358 Analysis of some astriclypeids (Echinoidea Clypeast- eroida) Paolo Stara1* & Luigi Sanciu2 1Centro Studi di Storia Naturale del Mediterraneo - Museo di Storia Naturale Aquilegia, Via Italia 63, Pirri-Cagliari and Geomuseo Monte Arci, Masullas, Oristano, Sardinia, Italy; e-mail: [email protected] *Corresponding author The systematic position of some astriclypeid species assigned through times to the genera Amphiope L. Agassiz, 1840 and Echinodiscus Leske, 1778 is reviewed based on the plating ABSTRACT pattern characteristics of these two genera universally accepted, and on the results of new studies. A partial re-arrangement of the family Astriclypeidae Stefanini, 1912 is herein pro- posed, with the institution of Sculpsitechinus n. g. and Paraamphiope n. g., both of them char- acterized by a peculiar plating-structure of the interambulacrum 5 and of the ambulacra I and V. Some species previously attributed to Amphiope and Echinodiscus are transferred into these two new genera. Two new species of Astriclypeidae are established: Echinodiscus andamanensis n. sp. and Paraamphiope raimondii n. sp. Neotypes are proposed for Echin- odiscus tenuissimus L. Agassiz, 1840 and E. auritus Leske, 1778, since these species were still poorly defined, due to the loss of the holotypes and, for E. auritus, also to the unclear geographical/stratigraphical information about the type-locality. A number of additional nom- inal fossil and extant species of "Echinodiscus" needs revision based on the same method.

There were two international echinoderm meetings. Acanthaster planci made the newspapers again, as a result of its coral chomping activities on various South Pacific islands. t~;'2ric3nscientists studied sea cucumber culturing techniques in China, In the middle of all this excitement, we neglected to issue a Newsletter. This time, we're six months late. We're sorry about the poor quality of many of the pages in this issue. A bad batch of mimeograph stencils coupled with a temperamental machine caused us some headaches. J;vehope to do better next time.

E-mail: [email protected] 4Corresponding author Abstract A new species of monophorasterid sand dollar, Monophoraster telfordi n. sp., is described from the Early Miocene basal horizons of the Chenque Formation of Patagonia, Santa Cruz Province, in southern Argentina. The new taxon raises the number of known species in the family to six, and represents first unequivocal record of the genus for the Early Miocene of South America. It is therefore also the oldest member of the genus. M. telfordi is characterized by its test width to length ratio, which is much higher than for the other two described species in the genus, but less than that known for the extremely wide members of the sister taxon, Amplaster. M. telfordi is also unusual among monophorasterids in lacking broad conti- nuity between basicoronal and post-basicoronal plates in the oral interambulacra. -

Evolutionary Modification of Mesenchyme Cells in Sand Dollars in the Transition from Indirect to Direct Development
EVOLUTION & DEVELOPMENT 9:3, 257–266 (2007) Evolutionary modification of mesenchyme cells in sand dollars in the transition from indirect to direct development Mamiko Yajima Tateyama Marine Laboratory, Marine and Coastal Research Center, Ochanomizu University, 11 Koyatsu, Tateyama, Chiba 294-0301, Japan Correspondence (email: [email protected]) Present address: Bio Med Molecular, Cellular Biology Biochemistry Department, Brown University, 185 Meeting Street, Providence, RI 02912, USA SUMMARY Peronella japonica, an intermediate type of cells (PMCs) and LMCs are similar to the SMCs of typical direct-developing sand dollar, forms an abbreviated pluteus, indirect developers, suggesting that heterochrony in the timing followed by metamorphosis within 3 days without feeding. In of mesenchyme cell ingression may have occurred in this this species, ingression of mesenchyme cells starts before species. EMCs disappeared after metamorphosis and LMCs hatching and continues until gastrulation, but no typical were involved in adult skeletogenesis. Embryos from which secondary mesenchyme cells (SMCs) migrate from the tip of micromeres were removed at the 16-cell stage formed the archenteron. Here, I investigated the cell lineage of armless plutei that went on to form adult skeletons and mesenchyme cells through metamorphosis in P. japonica and resulted in juveniles with normal morphology. These results found that mesenchyme cells migrating before hatching (early suggest that in P. japonica, LMCs form adult skeletal mesenchyme cells [EMCs]) were exclusively derived from elements, whereas EMCs are specialized for larval spicule micromeres and became larval skeletogenic cells, whereas formation. The occurrence of evolutionary modifications in cells migrating after hatching (late mesenchyme cells [LMCs]) mesenchyme cells in the transition from indirect to direct appeared to contain several nonskeletogenic cells. -

E-mail: [email protected] 5Corresponding author Abstract A new species of abertellid sand dollar, Abertella miskellyi n. sp., is described from the Miocene Camarones Formation of Patagonia, southern Argentina. The new taxon corroborates the existence of the genus in South America, given that Abertella is most common in the southeastern USA and the eastern coast of Central America. It is characterized by a unique basicoronal circle, in which the interambulacral basicoronal plates are very heterogeneous in size (small in interambulacrum 5, largest in interambulacra 2 and 3). Additionally, it features disjunct oral interambulacra involving two ambulacral plates in some of the interambulacra rather than one, thus being the most disjunct of all known species of Abertella. -

A Hydrodynamic Interpretation of Sand Dollar Morphology
BULLETIN OF MARINE SCIENCE, 31(3): 605-622, 1981 A HYDRODYNAMIC INTERPRETATION OF SAND DOLLAR MORPHOLOGY Malcolm Telford ABSTRACT Sand dollars are shallow-domed echinoids which act as lifting bodies in water currents, Coefficients of lift (CI) were determined experimentally in air for a lunulate species, Mel/ita qllinqlliesperforllta (0,040) and for a nonlunulate species, Echinarachllius parma (0.077). The difference in CI., which was shown to be statistically significant (P = 0.001), can be attributed partly to differences in camber and partly to the presence of lunules. Observations of water flow at 10 cm' sec-1 confirmed that flow was attached and of a lift- generating pattern. Flow around E. parma was hindered by a relatively large standing vortex at the anterior margin. For M. sexiesperforata, which is thinner edged and less steeply cambered, the flow was more perfectly attached; flow from oral to aboral surfaces via the lunules was distinct. Similarly, Encope emarginata had a closely attached flow with some passage through the anal lunule and ambital notches. Calculations from weight-length relationships and coefficients of lift indicated that M. qllillqlliesperfora({l should be able to maintain its position in more severe current regimes than could E. parma. Excess pressure on the oral surface of lunulate sand dollars is relieved by flow along pressure drainage channels which lead from the central region of the disc into the lunules and ambital notches. Scanning electron micrographs show that these lack the podia char- acteristic of food grooves and that podia in adjacent food-gathering areas sweep parallel to or away from the pressure drainage channels. -
