Additions to the Echinoid Fauna of New Zealand
90 [MAR. ADDITIONS TO THE ECHINOID FAUNA OF NEW ZEALAND D. G. MCKNIGHT New Zealand Oceanographic Institute, Department of Scientific and Industrial Research, Wellington (Received for publication 25 August 1967) SUMMARY Seven species of echinoids are added to the New Zealand fauna, two being described as new species of the genera Caenopedina and Spatangus. Described species, new to the fauna, are Gracilechinus multidentatus (H. L. Clark), Pourtalesia laguncula A. Agassiz, Hemiaster expergitus gibbosus A. Agassiz, and Gymnopatagus magnus A. Agassiz and H. L. Clark. Fragments of Spatangus, possibly hybrid S. thor Fell, and fragments of Echinocardium, almost certainly not E. cordatum (Pennant), are also described. INTRODUCTION Species described below are from recent archibenthal collections made by the New Zealand Oceanographic Institute. Genera new to New Zealand waters are Gracilechinus, Pourtalesia, Hemiaster, and Gymnopatagus. New species of the genera Caenopedina, Spatangus, and Echinocardium are described- Fragments of a possible hybrid form of Spatangus thor Fell are described. Described species new to the fauna are Gracilechinus multidentatus (H. L. Clark), Pourtalesia laguncula A. Agassiz, Hemiaster expergitus gibbosus A. Agassiz, and Gymnopatagus magnus A. Agassiz and H.

The lantern is powered by various paired and unpaired muscle groups. We describe how one set of these muscles, the lantern protractor muscles, has evolved a specialized morphology. This morphology is characterized by the formation of adaxially-facing lobes perpendicular to the main orientation of the muscle, giving the protractor a frilled aspect in horizontal section. Histological and ultrastructural analyses show that the microstructure of frilled muscles is largely identical to that of conventional, flat muscles. Measurements of muscle dimensions in equally-sized specimens demonstrate that the frilled muscle design, in comparison to that of the flat muscle type, considerably increases muscle volume as well as the muscle’s surface directed towards the interradial cavity, a compartment of the peripharyngeal coelom. Scanning electron microscopical observations reveal that the insertions of frilled and flat protractor muscles result in characteristic muscle scars on the stereom, reflecting the shapes of individual muscles. -

Bathyal Sea Urchins of the Bahamas, with Notes on Covering Behavior in Deep Sea Echinoids (Echinodermata: Echinoidea)

Pawson n, Doris J. Pawson National Museum of Natural History, Smithsonian Institution, WA DC 20013-7012, USA article info abstract Available online 24 January 2013 In a survey of the bathyal echinoderms of the Bahama Islands region using manned submersibles, Keywords: approximately 200 species of echinoderms were encountered and documented; 33 species were Echinodermata echinoids, most of them widespread in the general Caribbean area. Three species were found to exhibit Echinoidea covering behavior, the piling of debris on the upper surface of the body. Active covering is common in at Bathyal least 20 species of shallow-water echinoids, but it has been reliably documented previously only once Covering in deep-sea habitats. Images of covered deep-sea species, and other species of related interest, are Bahamas provided. Some of the reasons adduced in the past for covering in shallow-water species, such as Caribbean reduction of incident light intensity, physical camouflage, ballast in turbulent water, protection from desiccation, presumably do not apply in bathyal species. The main reasons for covering in deep, dark, environments are as yet unknown. Some covering behavior in the deep sea may be related to protection of the genital pores, ocular plates, or madreporite. Covering in some deep-sea species may also be merely a tactile reflex action, as some authors have suggested for shallow-water species. -
First Records, Rediscovery and Compilation of Deep-Sea Echinoderms in the Middle and Lower Continental Slope in the Mediterranean Sea
First records, rediscovery and compilation of deep-sea echinoderms in the middle and lower continental slope in the Mediterranean Sea Ariadna Mecho¹*, David S.M.

Passeig Marítim de la Barceloneta, 37-49, 08003 Barcelona, Spain 2 National Oceanography Centre, University of Southampton Waterfront Campus, European Way, Southampton SO14 3ZH, UK 3 Ocean and Earth Science, University of Southampton, National Oceanography Centre, Southampton SO14 3ZH, UK *Corresponding author e-mail address: [email protected] // Fax number: +34-932-309-555 ABSTRACT: This study provides a compilation of all available information on deep-sea echinoderms from the middle and lower-slopes in the Mediterranean Sea, with the aim of providing a unified source of information on the taxonomy of this group. Previous records of species are updated with new data obtained from 223 trawl hauls from 11 cruises from the submarine canyons and surrounding open slopes of the north-western Mediterranean Sea between 800 and 2845 m depth. Valid names, summary descriptions, bathymetric ranges and geographic distributions are given for all species. The new data report, for the first time, the presence of the Atlantic echinoid Gracilechinus elegans (Düben and Koren, 1844) in the Mediterranean Sea. We also report the presence of the endemic holothurians Hedingia mediterranea (Bartolini Baldelli, 1914), dredged only once previously in 1914 in the Tyrrhenian Sea, and Penilpidia ludwigi (von Marenzeller, 1893), known previously only from three samples, two in the Aegean Sea and one in the Balearic Sea.
