1 SMITHSONIAN INSTITUTION UNITED STATES NATIONAL MUSEUM Bulletin 201 A REVIEW OF THE MYSIDACEA OF THE UNITED STATES NATIONAL MUSEUM BY WALTER M. TATTERSALL UNITED STATES GOVERNMENT PRINTING OFFICE WASHINGTON : 195 For sale by the Superintendent of Documents, U. S. Government Printing Office Washington 25, D. C. - Price S1.00 (Paper) ADVERTISEMENT The scientific publications of the National Museum include two series known, respectively, as Proceedings and Bulletin. The Proceedings series, begun in 1878, is intended primarily as a medium for the publication of original papers, based on the collections of the National Museum, that set forth newly acquired facts in biology, anthropology, and geology, with descriptions of new forms and re- visions of limited groups. Copies of each paper, in pamphlet form, are distributed as published to libraries and scientific organizations and to specialists and others interested in the different subjects. The dates at which these separate papers are published are recorded in the table of contents of each of the volumes. The series of Bulletins, the first of which was issued in 1875, con- tains separate publications comprising monographs of large zoologi- cal groups and other general systematic treatises (occasionally in sev- eral volumes), faunal works, reports of expeditions, catalogs of type specimens, special collections, and other material of similar nature. The majority of the volumes are octavo in size, but a quarto size has been adopted in a few instances in which large plates were regarded as indispensable. In the Bulletin series appear volumes under the heading Contributions from the United States National Herbarium, in octavo form, published by the National Museum since 1902, which contain papers relating to the botanical collections of the Museum. The present work forms No. 201 of the Bulletin series. Remington Kellogg, Director, United States National Museum.

Sars, 1907 (Crustacea: Mysidacea) was recorded for the first time in the Netherlands in 1997. In the summer of 1998 extremely high den- sities (>6 ind. 1-1) of this neozoon were recorded in one of the Biesbosch reservoirs (Honderd en Dertig). This high abundance can not be explained by a recent invasion. Either H. anomala reached the Nether- lands via the River Rhine, probably aided by shipping, or through transport with ballast water from the Baltic or Black Sea. The invasion had dramatic effects on the zooplankton composition and abundance: from the end of August onwards hardly any Anomopoda, Ostracoda, Rotifera and invertebrate predators (Leptodora kindti and Bythotrephes longimanus) were present.

Four species of Lophogastrida and 33 species of Mysida were identifi ed. A new genus, Neoamblyops, and six new species, Ceratomysis japonica, C. orientalis, Holmesiella bisaetigera, Mysimenzies borealis, Neoambly- ops latisquamatus, and Paramblyops hamatilis, are described. Key words: Crustacea, Lophogastrida, Mysida, deep water, northern Japan, new genus, new species. Introduction Mysidaceans (Lophogastrida and Mysida) from deep waters off the Pacifi c coast of the north- ern Honshu, Japan, have been reported by W. Tattersall (1951), Birstein and Tchindonova (1958), Taniguchi (1969), Murano (1975, 1976), Fukuoka et al. (2005), and Fukuoka and Murano (2006). To date, two species of Lophogastrida and 11 species of Mysida have been recorded (Table 1). The present paper provides the taxonomic result of mysidacean specimens collected from deep waters off the northern Japan during a research project entitled “Research on Deep-sea Fauna and Pollutants off Pacifi c Coast of Northern Japan” as part of the “Study on Deep-Sea Fauna and Conservation of the Deep-Sea Ecosystem” conducted by the National Museum of Nature and Sci- ence, Tokyo.

    Soft−part preservation in two species of the arthropod Isoxys from the middle Cambrian Burgess Shale of British Columbia, Canada DIEGO C. GARCÍA−BELLIDO, JEAN VANNIER, and DESMOND COLLINS García−Bellido, D.C., Vannier, J., and Collins, D. 2009. Soft−part preservation in two species of the arthropod Isoxys from the middle Cambrian Burgess Shale of British Columbia, Canada. Acta Palaeontologica Polonica 54 (4): 699–712. doi:10.4202/app.2009.0024 More than forty specimens from the middle Cambrian Burgess Shale reveal the detailed anatomy of Isoxys, a worldwide distributed bivalved arthropod represented here by two species, namely Isoxys acutangulus and Isoxys longissimus. I. acutangulus had a non−mineralized headshield with lateral pleural folds (= “valves” of previous authors) that covered the animal’s body almost entirely, large frontal spherical eyes and a pair of uniramous prehensile appendages bearing stout spiny outgrowths along their anterior margins. The 13 following appendages had a uniform biramous design—i.e., a short endopod and a paddle−like exopod fringed with marginal setae with a probable natatory function. The trunk ended with a flap−like telson that protruded beyond the posterior margin of the headshield. The gut of I. acutangulus was tube−like, running from mouth to telson, and was flanked with numerous 3D−preserved bulbous, paired features inter− preted as digestive glands. The appendage design of I. acutangulus indicates that the animal was a swimmer and a visual predator living off−bottom. The general anatomy of Isoxys longissimus was similar to that of I. acutangulus although less information is available on the exact shape of its appendages and visual organs.

Mees University of Gent, Depa rtment of Biology, Marine Biology Section, Ledeganckstraat 35, B-9000 Gent, Belgium Key words: stomach content, consumption, Mysidacea, flatfish, gobies, gadoids, clupeoids Published in Journal of Fish Biology 1999, 55: 704-719 Abstract. The demersal fish fauna of the mesohaline zone of the Westerschelde estuary (south -west Netherlands) was sampled intensively in the period 1990-1992. Almost 500 beam trawl samples were taken in both subtidal (330 samples) and intertidal (144 samples) habitats. These yielded 44 fish species, mostly as juveniles. The area was found to function as a nursery for several demersal fish species. and harboured large populations ofhyper - benthic mysids. Three gobies, three flatfish, one clupeoid and one gadoid dominated the fish fauna, while three mysid species were important components of the holohyperbenthos. From c. 1500 stomach contents of 25 fish species, 44 prey species were identified, the most abundant of which were also common in the hyperbenthal. The demersal fish community consisted of a group that foraged subtidally on fast-moving epi- and hyperbenthic prey (for example gadoids, gobies and clupeoids) and a group that foraged on slow-moving or sessile endobenthic organisms, mainly in intertidal areas (for example most flatfish species). Mysidacea occurred in >50 % stom - achs analysed and were taken as prey by 19 of the 25 fish species. Mysids were most important in the diets of Pomatoschistus minutus, P.

    After 100 years: a detailed view of an eumalacostracan crustacean from the Upper Jurassic Solnhofen Lagerstätte with raptorial appendages unique to Euarthropoda PAULA G. PAZINATO , CLÉMENT JAUVION , GÜNTER SCHWEIGERT, JOACHIM T. HAUG AND CAROLIN HAUG Pazinato, P. G., Jauvion, C., Schweigert, G., Haug, J. T., & Haug, C. 2020: After 100 years: a detailed view of an eumalacostracan crustacean from the Upper Jurassic Solnhofen Lagerstätte with raptorial appendages unique to Euarthropoda. Lethaia, https://doi.org/10.1111/let.12382. The Solnhofen Konservat‐Lagerstätte yields a great number of remarkably preserved fossils of eumalacostracan crustaceans that help us understand the early radiation of several groups with modern representatives. One fossil from there, Francocaris grimmi Broili, 1917 is a small shrimp‐like crustacean originally described about 100 years ago as a mysidacean crustacean (opossum shrimps and relatives) from latest Kimmeridgian – early Tithonian (Upper Jurassic) of the Solnhofen Lithographic Limestones of South- ern Germany. New material with exceptionally preserved specimens, allied with mod- ern imaging techniques (mostly composite fluorescence microscopy), allows us to provide a detailed re‐description of this species. The most striking feature of Franco- caris grimmi is an extremely elongated thoracopod 7 with its distal elements forming a spiny sub‐chela. This character supports a sister group relationship of Francocaris grimmi with Eucopiidae, an ingroup of Lophogastrida, pelagic peracaridans common in marine environments throughout the world. We also discuss other supposed fossil representatives of Lophogastrida, identifying all of them as problematic at best. The structure of the sub‐chela in F. grimmi indicates an original use in raptorial behaviour. Francocaris grimmi appears to be unique in possessing such a far posterior sub‐chelate appendage as a major raptorial structure.

The traditional view of malacostracan posterior striking such that Makarov (1978), so taken by it, anatomy is not sustainable, viz., that the free telson, when present, bears the anus near the base. The anus either can oc- suggested that this region be given its own descrip- cupy a terminal, sub-terminal, or mid-ventral position on the tor, the urosome. In the classic interpretation, the telson; or can be located on the sixth pleomere – even when a so-called telson of arthropods is homologized with free telson is present. Furthermore, there is information that the last body unit in Annelida, the pygidium (West- might be interpreted to suggest that in some cases a telson can heide and Rieger, 1996; Grüner, 1993; Hennig, 1986). be absent. Embryologic data indicates that the condition of the body terminus in amphipods cannot be easily characterized, Within that view, the telson and pygidium are said though there does appear to be at least a transient seventh seg- to not be true segments because both structures sup- ment that seems to fuse with the sixth segment.

    Electricity Sector Planning for the Philippine islands: Considering Centralized and Decentralized Supply Options 1, 2 1 Paul Bertheau , Catherina Cader 1Reiner Lemoine Institut, Rudower Chaussee 12, 12489 Berlin, Germany 2Europa-Universität Flensburg, Auf dem Campus 1, 24943 Flensburg, Germany email: [email protected] ABSTRACT For archipelagic states such as the Philippines, it is important to evaluate centralized and decentralized approaches to electricity supply to ensure that the many and far-flung islands receive affordable, reliable and sustainable electricity. This study compares the feasibility of (I) submarine cable interconnection and (II) renewable energy based hybrid system development for 132 islands. For (I), we conduct a geospatial analysis and use an algorithm to compute the optimized grid outline, taking into account bathymetric models. For (II) we apply an optimization tool that computes for each island the least-cost power generation option, taking into account diesel generator, solar photovoltaic systems, battery storage, and electricity demand. The results indicate that a grid extension of 2,239 km submarine cable and 1,752 km land cable would be required to connect all of the islands considered. The overall investment under the given cost assumptions amounts to more than 3 billion USD for submarine cable interconnection and more than 700 million USD for a hybridized system development. Nevertheless, submarine cable interconnection is the most economically feasible option for 35 islands and can reduce power generation costs by up to 0.21 USD/kWh. A sensitivity analysis reveals that submarine cable interconnection remains the cost-effective option for most of the identified islands, even with costs increasing by 90%.

    MINISTERIE VAN ONDERWIJS, KUNSTEN EN WETENSCHAPPEN ZOOLOGISCHE MEDEDELINGEN UITGEGEVEN DOOR HET RIJKSMUSEUM VAN NATUURLIJKE HISTORIE TE LEIDEN DEEL XXX, No. 12 6 APRIL 1949 THE ISOPODA AND TANAIDACEA OF THE NETHERLANDS, INCLUDING THE DESCRIPTION OF A NEW SPECIES OF LIMNORIA by L. B. HOLTHUIS (With four textfigures) The Isopod and Tanaidaoean Crustacea of the Netherlands have not been treated as a whole since 1889, when Hoek published the second part of his Crustacea Neerlandica dealing with the Isopoda and Amphipoda. Hoek in this paper mentioned 25 species of Isopoda, 9 of which are marine forms, 1 a freshwater form and 15 terrestrial, no Dutch Tanaidacea were known to Hoek. At present we know 49 species of Dutch Isopoda, of which 20 are marine, 2 are freshwater forms and 27 are terrestrial, furthermore three species of Tanaidacea are known from this country. The present paper is an enumeration of all Dutch species of the two above mentioned groups, with their distribution within our country and, if necessary, with remarks on their synonymy and ecology. A volume on the Isopoda and Tanaidacea for the series "Fauna van Nederland", written in the Dutch language is now ready for the press and will be published in the course of time; in this volume a complete bibliography of the Dutch Isopoda is given, so that in the present paper only the most necessary references are made. The Isopoda found in Dutch greenhouses and those belonging to the family Armadillidiidae are treated here only summarily, as they have been dealt with more extensively in previous papers (Holthuis, 1946a, b).
