项目摘要

In order to remove a difficulty to access type materials described by Japanese researchers, this project was done, in which we investigated all classical type materials stored in main three institutions and reviewed their modern taxonomic implications. The three times visiting investigations in Tohoku University, Four times in Hokkaido University, two times in Tsukuba University, respectively, brought a fruitful result. The main works during each visiting research was to find type materials (mainly thin sections) listed in the type catalogue (Sugiyama and Ezaki, 2002 ; 2004). Confirmed materials were scanned by digital scanner and filed as digital pictures with original records collected from section labels, which were precisely compared with the original description text. Total scanned files reaches up to 1,200 and all information collected from type section labels and description by original authors compiled into data files. These data also added into the catalogue by Sugiyama and Ezaki (2002) with depository, revised information and pictures, and was issued as the latest type catalogue of Paleozoic corals described by Japanese researchers.Among the types, assigned into 22 genus 34 species by Yabe and Hayasaka (1915, 1916, 1920), 33 type materials already have been confirmed in Tohoku University. Several type materials designated to the other universities have been found in Hokkaido University ; such as the types by Ozawa (1925), Sugiyama (1940), and Yokoyama (1960). The resting problems are ; to clarify the materials yet registered or illustrated, to return back to the original depository, to continue the same investigation at the remaining institutions, to construct the total database containing all identified coral records.

为了消除日本研究人员描述的获取类型材料的困难，本项目调查了主要三个机构储存的所有经典类型材料，并回顾了它们的现代分类学意义。三次在东北大学、四次在北海道大学、两次在筑波大学的访问考察，取得了丰硕的成果。每次访问研究的主要工作是寻找类型目录中列出的类型材料(主要是薄片)(Sugiyama和Ezaki，2002；2004)。确认的材料用数字扫描仪扫描，并以数字图片的形式存档，原始记录收集自章节标签，并与原始描述文本进行精确比对。总共扫描的文件多达1,200个，从类型、章节标签和原始作者的描述中收集的所有信息都汇编到数据文件中。这些资料还被添加到Sugiyama和Ezaki(2002)的目录中，并附有保存、修订的信息和图片，作为日本研究人员描述的最新的古生代珊瑚模式目录发布。在Yabe和Hayasaka(1915、1916、1920)划分的22属34种模式中，东北大学已经确认了33种模式物质。在北海道大学发现了几种指定给其他大学的类型材料，如小泽(1925)、杉山(1940)和横山(1960)的类型。尚待解决的问题是：澄清尚未登记或说明的材料、返回原始保存库、在其余机构继续进行同样的调查、建立包含所有已确定的珊瑚记录的总数据库。
