Three deep-water species of the north-eastern Atlantic have been studied: Caryophyllia abyssorum Duncan, 1873, C. calveri Duncan, 1873, C. sarsiae n.sp. Of these only C. abyssorum has not been found in the Mediterranean. In the north-eastern Atlantic these species appear characteristic of somewhat different depths, but occasionally can be found together. Obtained by early deep-sea expeditions (“Porcupine” cruise of 1870, cruises of Prince Albert I of Monaco), all three species have been previously confused and assigned, chiefly, to the little-known fossil species C. arcuata and C. cylindracea. In order to show the world-wide confusion about C. arcuata, some other records, from Cape Verde Islands to Japan through Antarctica, are quoted.

The genus Opaliopsis from Brazil is revised based on three deep-water species. Opaliopsis atlantis (Clench & Turner, 1952) is confirmed as occurring in north-eastern and south-eastern localities. Opaliopsis opalina (Dall, 1927) is reported for the first time in the south-western Atlantic. A new species, Opaliopsis cearense, is described from the north-eastern Brazilian coast, and is distinguished by its large number of fine spiral cords per teleoconch whorl.

AbstractRhamphobrachium (Rhamphobrachium) agassizii is reported from the Cantabrian Sea, Spain, from depths of 925–1207 m. This is its first record off the Iberian Peninsula and in European waters, representing its northernmost distribution in the North Atlantic Ocean to date. Previous reports of R. (R.) agassizii from the eastern and western North Atlantic demonstrate its apparent amphi-Atlantic distribution, which appears consistent with the distribution of the main Atlantic currents. It is a typical deep-water species with its deepest record at 2165 m from the Azores archipelago. The specimens were collected singly at two stations, attesting to the rarity of the species in contrast to its congener R. (Spinigerium) brevibrachiatum which was the most dominant polychaete species in a previous study.

Four deep-water species of stalked barnacles were collected by the manned submersibles Jiaolong and Shenhaiyongshi during recent expeditions. Trianguloscalpellum regium (Wyville-Thomson, 1873), collected from the Mariana Trench at a depth of 5,462 m, represents a new distribution record. Glyptelasma gigas (Annandale, 1916), Poecilasma litum Pilsbry, 1907 and Poecilasma obliqua Hoek, 1907, collected from the South China Sea, are recorded for the first time from a mud volcano environment. Detailed photographs of these four species are presented and their partial sequences of 16S rRNA and mt COI genes are provided.

Nongeniculate calcareous algae are bio-constructors of many marine habitats, some of which are considered biodiversity hotspots. The genus Sporolithon is widely distributed around the world. As part of a review of material from the Brazilian continental shelf we found Sporolithon episoredion, that extend its distribution range into the Atlantic Ocean, Sporolithon ptychoides, which is widely distributed across oceans, and a new species of this genus named Sporolithon elevatum sp. nov. This species presents sorus 2–3 cells elevated above the thallus that sloughs off when senescent, paraphyses with 2–3 cells and a basal layer of elongated cells in areas where sporangia develop. The new species was found at 133 m depth. This study contributes to the understanding of the diversity in this genus and indicates the importance of systematic studies in the framework of conservation programs and evaluation of impacts in an area under exploitation activities.

Abstract. From a numerical analysis of deep water Neogene and Quaternary Ostracoda from D.S.D.P. sites in the S. W. Pacific, it is shown that the Miocene to Quaternary interval saw a large scale invasion by bathyal stocks of the abyss. This invasion was progressive and cumulative and resulted in abyssal faunas being much more diverse in the Quaternary than they had been in the Miocene. This major palaeoecological shift also occasioned a concommitant decline in bathyal faunas over the same interval. The breakdown of bathyal and abyssal isolation resulted from the Miocene onwards, in a progressive increase in the number of species which were able, contemporaneously, to live at both bathyal and abyssal palaeodepths.The study shows deep water faunas of this age to be much more diverse than previous studies have indicated. Ninety-one genera with autochthonous deep water species are encountered in this study. These genera are listed with the numbers of species of each genus and their depth distribution for Miocene, Pliocene and Quaternary respectively. Overall species diversity declines from the Miocene to the Pliocene but steeply increases into the Quaternary. It is suggested that the Pliocene impoverishment may in part be an artefact, occasioned by abnormally high Miocene diversity.It is shown that the phenomena outlined above are, to varying degrees, illustrated by all of the 6 groups into which the fauna is divided. It is suggested that certain of these phenomena, such as the major downslope migration from the Miocene onwards, may be detectable in other parts of the world’s oceans.

Until recently, only the following seven species of marine eels were known to exist in waters off British Columbia (based on literature sources and museum records): Nemichthys scolopaceus, and Avocettina infans (Nemichthyidae, snipe eels), Xenomystax atrarius (Congridae, conger eels), Serrivomer jesperseni (Serrivomeridae, sawtooth eels), Cyema atrum (Cyematidae, bobtail eels), Synaphobranchus affinis (Synaphobranchidae, cutthroat eels), and Thalassenchelys coheni (Colocongridae, worm eels). Histiobranchus bathybius (also in the Synaphobranchidae) is expected to occur in British Columbia, since its range extends from Mexico to Alaska. Recent surveys to determine the viability of crab fisheries facilitated the collection of non-game fishes from by-catch in bottom-trawl samples. Several eels were collected between 2004 and 2006, and they were originally identified as Serrivomer jesperseni (Serrivomeridae). Re-examination of these specimens indicates that they all are duckbill eels (Nettastomatidae), the first records of this family north of 45°39'N along the North American Pacific coast. Both Venefica ocella and V. tentaculata are represented, with V. ocella found farther north than V. tentaculata. All British Columbia specimens are housed at the Royal British Columbia Museum. The collection of new deep-water species in British Columbia reinforces the value of survey sampling to improve our knowledge of biodiversity.

Deep-sea pycnogonid material collected during the N/O Alis Campagnes Norfolk 2 to New Caledonia in 2003 and Salomon 2 to the Solomon Islands in 2004, together with two samples from the BOA0 and BOA1 Campagnes to Vanuatu in 2004–2005, has been analyzed. This includes only the second collection of deep-sea pycnogonids from the Solomon Islands. The material includes 22 specimens from seven species from New Caledonia, taken at depths from 265 to 1150 m, 95 specimens from 14 species from the Solomon islands, at depths from 336 to 1218 m, and two specimens of one species from Vanuatu (864–927 m depth). The first male of Ascorhynchus constrictus is described, including the first description of the anterior legs. A new species of Ascorhynchus is partially described, but not named owing to its incompleteness. Seven of the species are new to the Melanesia region, including a notable range-extension for Colossendeis tasmanica. The local zoogeography of these deep-water species is discussed.

The Relationship

The Bodo of the North Eastern region of India have their own kinship system to maintain social relationship since ancient periods. Kinship is the expression of social relationship. Kinship may be defined as connection or relationships between persons based on marriage or blood. In each and every society of the world, social relationship is considered to be the more important than the biological bond. The relationship is not socially recognized, it fall outside the realm of kinship. Since kinship is considered as universal, it plays a vital role in the socialization of individuals and the maintenance of social cohesion of the group. Thus, kinship is considered to be the study of the sum total of these relations. The kinship of the Bodo is bilateral. The kin related through the father is known as Bahagi in Bodo whereas the kin to the mother is called Kurma. The nature of social relationships, the kinship terms, kinship behaviours and prescriptive and proscriptive rules are the important themes of the present study.
