P. Payne MSc Thesis, Department of Biodiversity and Conservation Biology, University of the Western Cape. Seamounts are poorly understood ubiquitous undersea features, with less than 4% sampled for scientific purposes globally. Consequently, the fauna associated with seamounts in the Indian Ocean remains largely unknown, with less than 300 species recorded. One such feature within this region is Walters Shoal, a shallow seamount located on the South Madagascar Ridge, which is situated approximately 400 nautical miles south of Madagascar and 600 nautical miles east of South Africa. Even though it penetrates the euphotic zone (summit is 15 m below the sea surface) and is protected by the Southern Indian Ocean Deep- Sea Fishers Association, there is a paucity of biodiversity and oceanographic data.

N. Severtzov Institute of Ecology and Evolution of RAS, Moscow, Russia. E-mail: [email protected], [email protected] Abstract The first complete re-description of mud-dwelling axiid Leonardsaxius amurensis (Kobjakova, 1937) (Crustacea: Deca- poda: Axiidea) is presented based on the holotype and freshly collected specimens from Vostok Bay, Russia coast of the Sea of Japan. The species is mostly morphologically similar to Leonardsaxius spinulicauda (Rathbun, 1902) known from Pacific coasts of North America from Vancouver to California but can be morphologically separated mainly by morphol- ogy of carapace and coloration of cornea of eyes. Remarks on distribution of Leonardsaxius amurensis (Kobjakova, 1937) and the second axiid species, Boasaxius princeps (Boas, 1880), known along Russian coastline of the Sea of Japan are given.

    MARINE ECOLOGY PROGRESS SERIES Vol. 215: 169–177, 2001 Published May 31 Mar Ecol Prog Ser Phylogeography of the invasive polychaete Sabella spallanzanii (Sabellidae) based on the nucleotide sequence of internal transcribed spacer 2 (ITS2) of nuclear rDNA F. P. Patti*, M. C. Gambi Stazione Zoologica ‘A. Dohrn’, Laboratorio di Ecologia del Benthos, 80077 Ischia (Napoli), Italy ABSTRACT: Genetic relationships between different populations of the invasive species Sabella spallanzanii (Gmelin, 1791) (Polychaeta, Sabellidae) are investigated through the use of the internal transcribed spacer 2 (ITS2) of the nuclear ribosomal DNA (285 bp). Samples were taken from South Australian waters (3 populations), the Mediterranean Sea (8 populations) and the French Atlantic coast (1 population). The ITS2 sequences were analyzed using both maximum parsimony and unweighted pair-group mean analysis (UPGMA) algorithms; results showed genetic disjunction between the Australian and the Mediterranean populations. Within the Mediterranean populations, 3 different sub-groups, corresponding to different sub-basins, could be clearly detected (Northwest- ern, Central and Eastern basins). The Atlantic population showed strong differences with the Mediterranean and Australian populations, but did not allow the identification of the source of intro- duction from Europe to Australia. Data also suggest the occurrence of a reduced genetic variability of the Australian populations, probably due to the ‘founder effect’ of one introduction, either via ballast waters or hull fouling. The recent description of the life cycle and larval development of S. spallan- zanii in the Mediterranean Sea, with a long pelagic larval phase and a post-settlement stage of meta- morphosis (approx. 25 d), supports the hypothesis of introduction via ballast waters (larval pool).

Abstract Ghost shrimps of Callianassidae and Ctenochelidae are soft-bodied, usually heterochelous decapods representing major bioturbators of muddy and sandy (sub)marine substrates. Ghost shrimps have a robust fossil record spanning from the Early Cretaceous (~ 133 Ma) to the Holocene and their remains are present in most assemblages of Cenozoic decapod crustaceans. Their taxonomic interpretation is in flux, mainly because the generic assignment is hindered by their insufficient preservation and disagreement in the biological classification. Fur- thermore, numerous taxa are incorrectly classified within the catch-all taxonCallianassa . To show the historical patterns in describing fos- sil ghost shrimps and to evaluate taphonomic aspects influencing the attribution of ghost shrimp remains to higher level taxa, a database of all fossil species treated at some time as belonging to the group has been compiled: 250 / 274 species are considered valid ghost shrimp taxa herein.

SCIENTIFIC COUNCIL MEETING — SEPTEMBER 1989 Lobster (Homarus omericanus) Abundance in the Canadian Maritimes Over the Last 30 Years, an Example of Extremes by D. S. Pezzack Benthic Fisheries and Aquaculture Division, Dept. of Fisheries and Oceans P. 0. Box 550, Halifax, Nova Scotia, Canada B3J 257 Abstract Lobster is one of the most important fisheries in inshore fishing communities of eastern Canada. During the last 30 years the fishery has experienced its lowest and highest landings in the 100 years of recorded landings. Landings in many parts of the coast reached record or near record lows in the late 1960's and early 1970's, then rose to high levels not experienced since 1900. Total Canadian lobster landings doubled between 1977 and 1986 and in some areas landings increased tenfold. The increase in landings during the last 10 years appears to be the result of increased recruitment. The recent increase in lobster landings have occurred in different stocks and management regimes, suggesting a wide spread environmental factor(s) as the primary cause. z Introduction Lobster is one of the most important fisheries in inshore fishing communities of eastern Canada (Fig.1), • representing 28% of the total landed value of Atlantic Canada fish in 1985. Lobsters are a long-lived species not usually subject to large fluctuations in abundance but during the last 30 years the fishery has experienced the en 44 lowest and highest landings in the 100 years of recorded landings (Fig.

OXFORD: DAVIES SOLD BY J. COOKE; AND BY MESSRS. CADELL AND r STRAND, LONDON. 1805. S.. Collingwood, Printer, Oxford, TO THE EMPEROR CAESAR ADRIAN AUGUSTUS, ARRIAN WISHETH HEALTH AND PROSPERITY. We came in the courfe of our voyage to Trapezus, a Greek city in a maritime fituation, a colony from Sinope, as we are in- formed by Xenophon, the celebrated Hiftorian. We furveyed the Euxine fea with the greater pleafure, as we viewed it from the lame fpot, whence both Xenophon and Yourfelf had formerly ob- ferved it. Two altars of rough Hone are ftill landing there ; but, from the coarfenefs of the materials, the letters infcribed upon them are indiftincliy engraven, and the Infcription itfelf is incor- rectly written, as is common among barbarous people. I deter- mined therefore to erect altars of marble, and to engrave the In- fcription in well marked and diftinct characters. Your Statue, which Hands there, has merit in the idea of the figure, and of the defign, as it reprefents You pointing towards the fea; but it bears no refemblance to the Original, and the execution is in other re- fpects but indifferent. Send therefore a Statue worthy to be called Yours, and of a fimilar delign to the one which is there at prefent, b as 2 ARYAN'S PERIPLUS as the fituation is well calculated for perpetuating, by thefe means, the memory of any illuftrious perfon.
