(Received Oct. 30th.; read Nov. 21st, 1936) In the summer of 1936, I have made a large co llection of fossil shells from the P leistocene deposit of Sisinai (about 20 km NNE of Sapporo). Cross-bedded brown sand containing numerous fo ssil is exposed on a cliff near Sisinai, and the Sisinai fauna jornprises Mollusca, F oraminifera, Ciripedia, Brachiopoda and Bry­ ozoa, and among them Mollusca and Foraminifera are dominant. 1 Recently Prof. N AGA0 ) reported the Pleistocene fossiliferous deposits in Hokkaido and mentioned 39 species of Molluscan fossil of Sisinai. The aistinguishable species in my collection is attained to 71 in total, of whicl:i.' 36 belong to Pelecypoda, 34 to Gastropoda and 1 to Brachiopoda. Among the 70 species of Mollusca, 54 have been specifically identified, while 16 remain undetermined. The latter include mostly very small forms and ~10 s t of them are probably new to science.

SUMMARY: The present-day brachiopods from the Mediterranean Sea were thoroughly described by nineteenth-century workers, to the extent that Logan’s revision in 1979 listed the same 11 species as Davidson, almost 100 years earlier. Since then recent discoveries, mainly from cave habitats inaccessible to early workers, have increased the number of species to 14. The validity of additional forms, which are either contentious or based on scanty evidence, is evaluated here. Preferred substrates and approximate bio-depth zones of all species are given and their usefulness for paleoecological reconstruction is discussed. A previous dearth of material from the eastern Mediterranean has now been at least partially remedied by new records from the coasts of Cyprus, Israel, Egypt, and, in particular, Lebanon and the southern Aegean Sea. While 11 species (79 % of the whole fauna) have now been recorded from the eastern basin, Terebratulina retusa, Argyrotheca cistellula, Megathiris detruncata and Platidia spp.

  • A Note on Dallina Septigera (Loven), (Brachiopoda, Dallinidae)
    J. mar. bioi. Ass. U.K. (1960) 39, 91-99 91 Printed in Great Britain A NOTE ON DALLINA SEPTIGERA (LOVEN), (BRACHIOPODA, DALLINIDAE) By D. ATKINS,D.Sc. From the Plymouth Laboratory (Plate I and Text-figs. 1-5) The discovery of a homoeomorph, Pallax dalliniformis, of Dallina septigera (Loven) dredged with that species (Atkins, 1960) and, it is believed, some• times confused with it, certainly by Fischer & Oehlert (1891), has made a brief redescription desirable. During the present work more than a hundred D. septigera of shell length 5-31 mm have been obtained, and most of them examined internally. The original description in Latin-without figures-of Dallina septigera (= Terebratula septigera) was by Loven in 1846 (p. 183). Unfortunately his description does not now clearly separate his species from Pallax dallini• formis, except perhaps his failure to mention the presence of dental plates, pedicle collar and spiculation. It is doubtful how much weight can be attached to this, for on the same page he failed to mention the presence of dental plates in Macandrevia cranium. He gave the length as 28 mm, width as 21·5 mm and depth as 17 mm. The Stockholm Natural History Museum, the most likely Museum to possess Loven's type specimen, unfortunately does not have it, and it is probable that he did not designate one. The Museum, however, does possess old collections of dried shells of this species from Norway and the ~orth Sea, which Loven probably studied. Through the kindness of Dr H.Mutvei a large specimen from these was loaned to me: he stated that it is not known with certainty whether it was collected before or after 1846-the date of publication of Loven's paper.

    Tertiary and Quaternary Brachiopods from the Southwest Pacific G. ARTHUR COOPER SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY NUMBER 38 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review.

The affinities of the SEAMOUNT 2 brachiopods are with the Mauritanian biogeographic province. Diversity and number of stations yielding brachiopods increase from south to north in the cluster of six seamounts (Meteor-Tyro) south of the Azores.

Zoosystema 30 (2) : 419-461. ABSTRACT Eight genera of recent brachiopods, i.e. Pelagodiscus, Novocrania, Cryptopora, Xenobrochus, Eucalathis, Campages, Megerlia and Th ecidellina have been identifi ed in the material from the Wallis and Futuna Islands, collected during the French cruise MUSORSTOM 7 in 1992. Nineteen genera of recent brachiopods, i.e. Lingula, Novocrania, Cryptopora, Basiliola, Abyssothyris, Xenobrochus, Dallithyris, Terebratulina, Eucalathis, Fallax, Septicollarina, Frenulina, Argyrotheca, Amphithyris, Leptothyrella, Dallina, Nipponithyris, Campages and Th ecidellina have been recognized in the material collected from the Fiji Islands during the two French cruises MUSORSTOM 10 and BORDAU 1 in 1998 and 1999. Two genera, Pelagodiscus and Megerlia, found in the Wallis and Futuna region have not been recognized in the material from Fiji. In turn, 13 genera reported from Fiji have not been found in the material from the Wallis and Futuna Islands. Four species are described as new: Xenobrochus rotundus n. sp., Leptothyrella fi jiensis n. sp., Nipponithyris lauensis n. sp. and Campages ovalis n. sp. Xenobrochus roduntus n. sp. diff ers from congeneric species in rounded outline and small foramen. It is characterized by the rudimentary to absent outer hinge plates and rounded, KEY WORDS anteriorly convex transverse band with a slight median fold.

  • Brachiopoda from the Gulf of Gascogne, France (Recent)
    SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY NUMBER 44 Brachiopoda from the Gulf of Gascogne, France (Recent) G. Arthur Cooper SMITHSONIAN INSTITUTION PRESS City of Washington 1981 ABSTRACT Cooper, G. Arthur. Brachiopoda from the Gulf of Gascogne, France (Recent). Smithsonian Contributions to Paleobiology, number 44, 35 pages, 5 figures, 3 plates, 1981.—Brachiopods collected during the operations of Biogas and Polygas Gulf of Gascogne Abyssal Survey, and Thalassa, Gulf of Gascogne Bathyal Survey of the Centre Oceanologique de Bretagne, are recorded and data concerning them noted. Most of the specimens taken in Biogas and Polygas are from depths ranging from 1010 meters to 4459 meters. The specimens taken by Thalassa are mostly from waters less than 1000 meters in depth. Twenty-one species in 14 genera are recognized, six of them, including a new species, hitherto not recorded from the Gulf of Gascogne, are starred: * Pela­ godiscus atlanticus (King), Crania anomala (Muller), C. anomala turbinata (Poll), * Cryptopora gnomon Jeffreys, Hispanuhynchia cornea (Fischer), Eucalathis ergastica Fischer and Oehlert, E. tuberata (Jeffreys), Terebratulina retusa (Linne), T retusa emarginata (Risso), Gryphus vitreus (Born), *G.P cooperi d'Hondt, Dallithyris? aff. D.? sphenoidea (Jeffreys), Platidia anomioides (Scacchi and Philippi), Megerlia truncata (Linne), M. echinata (Fischer and Oehlert), Pantellaria monstruosa (Scac­ chi), Macandrevia cranium (Muller), *M. novangliae Dall, * Fallax dallimformis Atkins, Dallina septigera (Loven), and *D. parva, new species. Five described species not previously recorded from the Gulf of Gascogne are: Pelagodiscus atlanticus (King), a world-wide abyssal form; Cryptopora gnomon (Jeffreys), widespread in the northern Atlantic; Macandrevia novangliae Dall, hitherto only known from deep water off the coast of New England, United States; Fallax dallimformis Atkins, newly discovered in the approaches to the English Channel; and Gryphus? cooperi d'Hondt recently described.

    SCIENTIFIC RESULTS OF ' EXPLORATIONS BY THE U. S. FISH COMMISSION STEAMER ALBATROSS. [Published by permiasion of Hon. Marshall McDonald, Commissioner of Fisheries.] No. XXXIV.—REPORT ON MOLLUSCA AND BRACHIOPODA DREDGED IN DEEP WATER, CHIEFLY NEAR THE HAWAIIAN ISLANDS, WITH ILLUS- TRATIONS OF HITHERTO UNFIGURED SPECIES FROM NORTHWEST AMERICA. By William Healey Ball, Honorary Curator of the Department of Mollusks. In the latter part of 1891 the Albatross was engaged in making soundings between tlie coast of California and the Hawaiian Islands, with the intention of obtaining a profile of the sea bottom for use in con- nection with plans for laying a submarine telegraph cable. This work was performed as rapidly as possible, and no delays made for dredging or other work not strictly germane to the purpose of the voyage until on approaching Honolulu the archibenthal plateau about the islands was reached, and here, in between 300 and 400 fathoms, eight hauls of the dredge were made, of which a table follows. Half a dozen small bottles, containing mollusks and brachiopods, were received in 1892, and the following account of their contents leads us to regret that more time could not have been devoted to dredging. The material obtained is not only very interesting, zoologically, but wholly new, not a single species heretofore described, either from the deep sea or from the Hawaiian Archipelago, being found among the dredgings. A new subgenus of Pleurotomidse, the hitherto unknown and very interesting soft parts of a species of Muciroa, regarded as belonging to the Verticordiidae, but now necessarily raised to family rank, sev- eral new Brachiopods, etc., are among the material secured, and described in the following pages.
