中国海粗毛猛水蚤科一新记录属和新种记述

通过对南海采集的沉积物进行分析,发现一新种奇足威伦狭腹猛水蚤,这也是首次在中国海报道威伦狭腹猛水蚤属。新种奇足威伦狭腹猛水蚤与同属其它种的主要区别特征是：身体表面除尾节有小刺外,其余各节表面均光滑;第四胸足外肢第三节内侧具两根刚毛;雌性第五胸足內肢具4根刚毛和刺,外肢顶端具一根尖刺,尾叉长约为宽的六倍。     

西沙群岛管枝藻目的分类研究

根据Feldmann(1938)的评述，管枝藻目的系统分类研究工作始于Schmitz(1879)，他首先创建了“group” Siphonocladaceae(发表名为Siphonocladiaceae)。又据Egerod(1952)的研究，Schmitz的“group”事实上只是一个科，Feldmann(1938)，Fritsch(1947)及其他人把管枝藻目的创建者归诸Schmitz是错误的。Schmitz在此科中收容了法囊藻(Valonia)，肋叶藻(Anadyomene)，小网藻(Microdictyon)，刚毛藻(Cladophora)，硬毛藻(Chaetomorpha)，黑孢藻(Pithophora)，气球藻(Botrydium)和暂定的网叶藻(Struvea)以及他的新属管枝藻(Siphonocladus)。De Toni(1889)将Schmitz的管枝藻科的各属分散在Order Confervoideae的刚毛藻科的刚毛藻亚科(Cladophoreae)、绵枝藻亚科(Spongocladieae)、小网藻亚科(Microdictyeae)、肋叶藻亚科(Anadyomene)和法囊藻亚科(Valonieae)中。Blackman and Tansley(1902)简历管藻目时下分管藻亚目(Siphoneae)包括无分隔的种类和管枝藻亚目(Siphonocladeae)包括分隔的种类；后者由孢根藻科(Gomontiaceae)，刚毛藻科(Cladophoraceae)，环藻科(Sphaeropleaceae)和法囊藻科(Valoniaceae)等四个科组成。     

中国东海和南海4个真虾(甲壳动物亚门:十足目:真虾下目)新记录种

采集自中国东海和南海的4个真虾物种,经研究发现为中国海域的新记录物种,即凯氏鞭腕虾（Lysmata kempi Chace,1997）,利普克鞭腕虾（Lysmata lipkei Okuno&Fiedler,2010）;透明近绿虾（Chlorocurtis jactans（Nobili,1904））和黑斑活额虾（Rhynchocinetes conspiciocellus Okuno&Takeda,1992）。本文描述了这四个物种的形态特征,编制了检索表,并对其分类地位进行了讨论。     

A new species of the genus Haloschizopera Lang, 1944(Copepoda,Harpacticoida, Miraciidae,Diosaccinae) from the East China Sea

A new species belonging to the genus Haloschizopera Lang, 1944 (Copepoda, Harpacticoida, Miraciidae, Diosaccinae) was identifi ed based on the samples collected from the East China Sea, near the off shore of Zhejiang Province, East China. The new species is closely related to H . pygmaea Norman & Sccot T., 1905 and shares a combination of the following features: A1 eight-segmented;A2 exp-2 with one distal seta, exp-3 with three setae;P1 endopodal segments subequal, enp-1 not exceeding exp-2;exp-3 of P3 with one inner seta, of P4 with two inner setae. The new species is characterized by the presence of one inner seta on P2 exp-3 of both sexes. It can also be distinguished from its congeners by the characters of female: P5 exopod subcircular, endopodal lobe extending beyond half-length of exopod;genital doublesomite ornamented with three dorsolateral rows of spinules on anterior part.     

南海海盆海山古地磁及海盆的形成演化

根据海山磁性反演获取的古地磁成果发现,南海海盆东部和西南部的运动形式、生成时代存在很大差异,东部海盆和西南部海盆之间由一条北北西走向的岩石圈压性左旋转换(性)断层——"南海海盆中央断裂"分界.结合已有的地质地球物理成果分析和论证,确定了南海海盆在古南海和与之接壤的华南地块南部边缘形成.南海海盆的形成演化分四个阶段:第一阶段,始新世"古南海断裂"产生,古南海被一分为二;第二阶段,渐新世东部海盆开始发育——扩裂;第三阶段,中中新世西南部海盆开始发育——张裂;第四阶段,南海海盆整体旋转,古南海圈闭.

亮钩虾属Genus Photis属于蜾蠃蜚科Corophiidae甲壳动物端足目(Crustacea:Amphipoda),全世界有近60种。本属为世界性分布,世界各大洋都有记载。 作者在系统整理和研究南海端足目标本中发现南海亮钩虾4种,其中有1新种,1种为中国沿海的首次纪录。新种的模式标本保存在中国科学院海洋研究所。     

西沙群岛马尾藻科研究Ⅱ

西沙群岛马尾藻种类较多，我们已在本刊12集上发表了“西沙群岛马尾藻科研究Ⅰ”，报道了五个种。在此基础上，本文将继续报道以下六种(其中包括四新种和两新记录)，即：叶囊马尾藻S. phyllocystum sp. nov.，细囊马尾藻S. parvivesiculosum sp. nov.，西沙马尾藻S. xishaense sp. nov.，陀螺叶马尾藻S. turbinatifolium sp. nov.，粉叶马尾藻S. glaucescens J.Ag.，厚叶马尾藻S. crassifolium J. Ag.。新种的模式标本均保存于中国科学院海洋研究所植物标本室。     

Five <Emphasis Type="Italic">Oncaea</Emphasis> species (Copepoda,Poecilostomatoida, Oncaeidae) from the Korean waters,with notes on the spatio-temporal distribution of Korean oncaeid species

Five Oncaea species were recorded on the basis of specimens collected using three type nets from the South Sea and the East Sea of Korea. These included the clevei-group of one species (O. clevei) and the venusta-group of four species (O. media, O. mediterranea, O. scottodicarloi, O. waldemari). The former has a dorsoposterior projection on the second pedigerous somite, while the latter do not bear any dorsal projection on the somite. Also, their spatio-temporal distribution are discussed in relation to temperature-salinity.     

On a new Siphonophora from the East China Sea and South China Sea

In the course of identifying the samples of Siphonophora from the East China Sea and South China Sea, a new Siphonophora, Vogtia microsticella sp. nov. , was noted. The new species is distinguished from other five species in the genus in nectophore as follows: Parahorse-shoe shaped with five bluntly rounded projections, the two projections below the ostium, i. e. the basal projections, approach each other. The dorsal facet is smooth without any gelatinous prominence. Smaller are the nectosac and the ostium.     

Descriptions of four new species of the genus Reticunassa Iredale, 1936 (Gastropoda: Nassariidae) from the northeastern coast of Taiwan Island and the South China Sea

In the present study, four new species of the genus Reticunassa Iredale, 1936 collected from Chinese waters are described and illustrated. Reticunassa hugokooli sp. nov., Reticunassa jungi sp. nov. and Reticunassa aureolineata sp. nov. were collected from the northeastern coast of Taiwan Island, whereas Reticunassa fuscofasciata sp. nov. was collected from the northeastern coast of Taiwan Island and the South China Sea. The four new species can be distinguished conchologically from other congeners mainly in protoconch, shell shape, sculpture, and coloration. These findings demonstrate that the biodiversity of this group in China might be largely underestimated.     

南海深海鱼类的初步报告

南海在我国濒临的四个海中面积最大，而其大陆架宽度则较狭窄，水深在200米以上的深海水域相当广阔。我国过去关于南海深海鱼类的研究报道极少，1962年《南海鱼类志》中曾记载过少数深海鱼类，但具有确切深度记录的仅有8种。在国外文献中，Gilbert和Hubbs(1920), Schultz(1938), Abe(1974 , 1975, 1976 )等曾报道过数种。 本文材料是1959-1960年在海南岛以东海域，水深200-1100米进行底栖生物拖网时所获得的标本。鉴定结果，共71种，分隶于37科，12目，其中34种为我国新记录，7种是我国在南海首次记录。 文内凡是我国新记录的种均有形态描述，并附有外形图,有些种作了分类上的讨论；对我国有过记录的种，只记有地理分布和标本采集记录。此外，就现有资料并参考有关深海鱼类文献，对这些种类的地理分布和深度分布也作了初步分析。由于调查范围较小，拖网次数不多，本文仅为南海鱼类区系提供了一些初步资料。丰富的南海深海鱼类区系，随着我国海洋调查事业的发展，还有待进一步深入研究。     

厦门近海尖梭螺属(软体动物门, 腹足纲, 梭螺科)一新记录种

在福建厦门近海采集到梭螺科Ovulidae尖梭螺属Cuspivolva 中国海新记录种1种, 即武装尖梭螺Cuspivolva bellica (C. N. Cate, 1973)。标本采自厦门近海低潮线附近, 栖息于鞭柳珊瑚Ellisella sp.的枝杈表面, 现保存于中国科学院南海热带海洋生物标本馆。本文对此新记录种的外部形态、生活习性和地理分布等进行了描述和记录, 并与近似种进行了比较和讨论。截至目前, 我国已知尖梭螺属共8种, 该新记录种的发现和报道, 进一步丰富了我国海域梭螺科物种的多样性。     

A unified assessment of marine Mediterranean assemblages: a lesson from benthic hydroids

Hydroids are important components of the communities of rocky bottom shallow coastal areas. The hydrozoan fauna of the Mediterranean Sea is probably one of most investigated in the world, with lots of faunistic and biogeographical studies. However, quantitative studies using the same sampling methodology and controlled sampling effort have been restricted to areas in the Western and Central Mediterranean. We compared hydroid assemblages in four areas of the Mediterranean Sea, from the Gulf of Cádiz to the South Adriatic Sea, following the same sampling and quantification methodology. Our analysis showed the dominant Atlantic character of the assemblages of the Gulf of Cádiz and the South Alboran Sea because of the influence of the inflowing Atlantic waters. Conversely, the hydroid assemblages of the North Alboran Sea were more similar to the assemblages in the Ligurian and in the South Adriatic, and with a number of species ranking between the observed in these two Mediterranean zones. Fourteen species were identified as making the most significant contributions to characterizing the Mediterranean hydroid species pool from a quantitative point of view. These taxa include species previously named as typical components of the Mediterranean hydroid fauna as well as those only recently recorded in the region (Eudendrium moulouyensis) and invaders such as Clytia hummelincki.     

南海地区明管虫属(多毛纲:欧努菲虫科)的两种报道,及乳突明管虫在中国海的首次记录

基于中国科学院海洋生物标本馆历年收藏的标本对明管虫属开展了分类学研究,共发现两种明管虫：Hyalinoecia tubicola （Müller,1776）（明管虫）和H.papillata Imajima,1999（乳突明管虫）。二者均采集于南海北部海域沙质基底,Hyalinoecia tubicola广泛分布于广东省沿岸海域向南至西沙群岛,H.papillata则首次报道于中国南海,其区别于H.tubicola在于第一疣足具伸长舌状、两侧边缘具有乳突的前刚叶（ vs.耳状前刚叶、边缘光滑）。本文详细提供了二者的形态学描述和绘图。

中国近海鹑螺科的研究

鹑螺科是中腹足目鹑螺总科中的一个小科,包括的种类不多,数量也不大,但是它的贝壳较大,又较有光泽,而且具有整齐的肋纹和色彩,所以是人们喜爱搜集的贝类之一。它们的肉均可食用,贝壳常同其他贝类的贝売和在一起烧制建筑用灰。这一科动物全部是暖水种,世界各暖海区都有分布,而以印度一西太平洋区的种类为最多,化石出现于第三纪。 本科动物的贝壳通常较薄,呈球形或卵圆形，螺旋部短,体螺层膨大,各层表面具有平滑的螺肋。壳口宽大,内面具沟纹,外唇薄或増厚形成一个具齿的环,水管沟宽短。成体不具厣。软体部分头大:前端膨大,触角长,呈圆柱状,眼位于其基部外侧的一个短柄上。吻极长,不能完全缩入壳内,呈管状,末端扩张形成蔷薇花状的唇部,伸展时长度可超过贝壳。水管长,伸展时可直立于贝売的背部。雄性交接器极长大,弯弓形,全长具沟,末端有一尖钩。为肉食性动物,常以海参等动物为食。 我国鹑螺科的种类过去金叔初和秉志、张玺、阎敦建等曾有零星记载,国外学者也有一些记载,但对各种的分布地点记载不详。我们根据中国科学院海洋研究所历年来采集保存的标本和全国海洋综合调查所采得的底栖动物标本进行了整理研究,共鉴定10种，其中1种仅在东海发现,4种为东海和南海共有,5种仅分布于南海;有一种,即黄口鹑螺在我国沿海尚系首次记录。

Winter distribution of diatom assemblages along the coastline of R. O. Korea in 2010

Diatoms are a globally successful and eukaryotic photosynthetic organism with an ornamented silica external wall. The relationship between their valve morphology and habitat means that diatoms can be used as bioindicators to characterize the aquatic environment. To estimate the differential distribution and diversity of diatom assemblages along the coastal line, we collected phytoplankton samples from 114 coastal sites of waters of R. O. Korea. We applied the unweighted pair-group technique usin...
