Image database system of type specimens of, Cenozoic smaller foraminiferal species, and taxonomic study of foraminifera from Japan.

为保证有孔虫分类的稳定性，本文建立了日本新生代小型有孔虫模式标本的图像数据库系统。在日本列岛及周边海域有孔虫物种数据库的模式标本上，我们对数据集进行了修订，并增加了一些额外的数据，并将其加载到网络系统中。关于日本及周边海域的有孔虫物种，我们考察了日本几个研究所和博物馆的全模和系列的保存状况。这一结果在日本古生物学会年会上发表。为了解该物种的形态变化和古生态背景，我们对各类型地点进行了调查，并收集了地形标本。利用低真空扫描电镜（L-SEM）、数字高清显微镜等对数百种有孔虫主要类型的图像数据进行分析，建立了有孔虫图像数据库。在未来正式发布之前，这个数据库暂时在Internet上向公众介绍。通过7期《foram - net》通讯，在熊本、秋田、加贺、仙台召开4次研究会议，通过电子邮件讨论动物分类，规划了有孔虫和其他微化石的分类学、有孔虫在古生态学、地层学、古生物地理学、古海洋学等方面的最新研究成果交流。

For stability of foraminiferal taxonomy, an image database system has been prepared on the type specimens of Cenozoic smaller foraminifera from Japan, as follows :1.On the database of foraminiferal species with the type specimen from the Japanese Islands and the surrounding seas, we revised the data set and added several additional data, and has loaded it up the internet systems.2.On foraminiferal species from the Japan and the surrounding seas, we inspected the state of storage of holotype and the type series at several institutes and museums in Japan. This result was reported at an annual meeting of the Palaeontological Society of Japan.3.To understand the morphologic variation and paleoecologic background of the species, we have surveyed each type locality, and have collected topotypic specimens.4.An image database of foraminifera was constructed on the base of image-data of primary types of a few hundreds species, which were made by using a low-vacuum scanning electron microscope (L-SEM), digital HD micro-scope and so on. This database is introduced to the public tentatively on the Internet before the future general release.5.The exchange of various information such as taxonomy on foraminifera and other microfossils, advanced researches of foraminifera on (paleo-)ecology, stratigraphy, (paleo-)biogeography, paleoceanography, etc. was planned through seven issues of news letter "Forams-Net", research meetings of four times held at Kumamoto, Akita, Kaga, and Sendai, the debate about zoological classification by E-mail, and so on.
