Taxonomical study of deep sea polychaetes and vestimentiterans from Indo-Pacific Ocean

对印度-太平洋地区收集的深海多毛类和前体动物进行了分类研究，并与世界各地已知的近亲进行了分类研究。第一年是用来收集来自世界各地的收藏品。作者使用DSRV“新海6500”潜航器在印度洋的Hakuho Knollo潜水。调查区域是如此寒冷的罗德里格斯三重交界处的一部分，这是印度洋构造最活跃的深海底部之一。这次潜水的着陆点是2448米深的波纹沙底，距离凯瑞油田不远。然后在去卡利烟囱的路上，我们发现了一个叫Kissho的烟囱。我们用吸音枪在烟囱附近收集动物。收集到大型腹足类蟹和大腹蟹（Austinograea rodrigezensis），大腹蟹的死壳，但发生了严重的问题，无法继续进行。然后用机械手采集了双壳类和腹足类的标本，但没有采集到多毛类的标本。因此，在这片深海热液区发现的更多的多毛类标本都是由DSRV的其他研究人员潜水收集的。在该地区发现了一种极接近太平洋的多毛纲类，属Branchipolynoe。在相模湾初岛冷海海域，我们发现了多毛纲动物，如Nereis surgaense、Euclymene uncinata、Maldane cristata、Lumbrineris japonica、Eunice mucronata、Paraonides nipponica等。另一方面，在冲绳海槽南恩西丘的收集中，我发现了一种未被描述的尤尼斯属物种，并准备了一份描述，提交给科学期刊。在整理鹦鹉螺科的过程中，我比较了国外同事提供的两种，发现它们是科学上的新物种。因此，三叉囊菌的描述和其他的描述现在正在印刷。最近，作者观察了从新西兰附近的兄弟火山口收集的veestimentiferans。这些物种也被认为是科学上的新物种，目前正在研究中。少

Deep sea polychaetes and vestimentiferans collected from Indo-Pacifice areas were taxonomically studies with therie relatives konown from the world-wide areas. The first year was spent to make collections from divers area of the world. The author could dive at Hakuho Knollo in Indian Ocean using DSRV Shinkai 6500. The surveyed area is a part of so-cold Rodriguez Triple Junction, one of the most tectonically active deep sea bottom in Indean Ocean. The landing place of this dive was the rippled sandy bottom at a depth of 2448 m, not far from the kairei field. Then on the way to Kali chimney, we found a chimney called Kissho. We collected animals near this chimney using a slurp gun. Large gastropods and bythograeid crabs(Austinograea rodriguezensis), dead shell of Alviniconhca, were collected, however a serious trouble wasa taken place and could not continue. Then some other specimens of bivalves and gastropods were sampled using manipulator, but without any polychaete specimens. Thus the … More polychaete specimens recored from this deep-sea hydrothermal field were all colledted by the other researchers dives of DSRV. A polynoids polychaete species very close to Pacific one of the genus Branchipolynoe were recored from the area.From off Hatsushima cold seap area in Sagami Bay, we could recored several species of polychaetes, such as Nereis surgaense, Euclymene uncinata, Maldane cristata, Lumbrineris japonica, Eunice mucronata, Paraonides nipponica. On the other hand, in the collection made from Minami Ensei Knoll, Okinawa Trough, I could find an undescribed species of the genus Eunice and prepared a description to submit a scientific journal.On the way of revision of the family Nautileniellidae, I could compare two species supplied by foreign coworkers and found them new to science. Thus Vesicomycola trifurcates was described and the description of the other is now printing.Very recently (, the author could observe vestimentiferans species collected from Brother Caldera, near New Zealand. These species are also recognized as new to science and now on the way of study. Less
