T.，M，x ′ rsaxccro和1%。，KANMEICA（.，1949年）发表了关于九州南部I-Iikaja inn t）ae Kuma rnassif上谷的二叠纪Kuma地层的初步报告，本文报道了该地层的详细资料，包括地层中的镰刀虫化石成分，并与其它化石进行了大量的对比讨论。日本列岛晚二叠世含化石地层，关于乌尔纳组的地层和岩相的简要说明，请读者参考以前发表的论文和本论文日文文本中的柱状底座，在这里，我将介绍一个fusulinid动物群的轮廓。在库玛组中，有4个层位产出了燧石，柱状剖面显示含有丰富的镰形虫化石。在区系中，最具特征的成员是姚氏藻属（Yaoeina）5种和绿腹藻属（Lancolina），所有种类都比球形亚贝亚inouyei DEPRAT）和Y.，katoi Ozawa.，最后两个是Yabeina globosa带的特征元素，该带迄今被认为是日本最年轻的fuslinid带。熊组的fusulinids组合代表了一个在日本没有记录的生物群，与Yabeina globosa带的动物群有明显的不同。Yabeina globosa带的动物群在日本广泛分布，并且总是包含Neoschwagerina的某些种，而在Kuma组中既没有Neoschwagerina的遗迹，也没有Yabeina globosa带的动物群共有的种。在Kuma组中，Yabeina globosa带出露的位置与Kuma组区域有些分离，因此，在野外很难确定地层关系。然而，熊组的动物群与Yabeina globosa带完全不同，生物学上比后者更先进。晚二叠世组广泛分布于日本诸岛的一些独立地区，例如，它们是水越组（T.，Matumoto和H.，HUZIMOTO）位于九州中部，白岩组（R.，T0 RIYAMA，M.常森组的上部，KATAYAMA）在山口县，Nukada和Maizuru地层（K.，NAKAZAWA），安波和其他地区（R.，在高知县的TORIYAMA）和Dodo（K.，K 0 NISHI）和丰马组（M.，美娜多）在北上的温泉，这些地层一般主要由黑色页岩、砂岩、显著的砾岩和少量的小灰岩、透镜体组成。砾岩包含花岗岩和其他各种火成岩的巨砾、鹅卵石和卵石。在石灰岩中，Yabeina shiraiwensis Ozawa，Y.，yasubaensis，TORIYAMA，熊豆绿球藻Lycolina kumaensis KANMERA（MS）L.，鸟屋井KANMERA（MS）和其他密切相关的形式。根据这些事实，我得出的结论是，熊组和上述其他含砾岩的建造的动物群构成了Lubeolina带（或Yabeina上部带），它与Yabeina globosa带不同。Kuma组动物群在具体组成上与Gubler（1935）在印度支那Cambodge描述的动物群以及Thompson和惠勒（1942，1948）在不列颠哥伦比亚省Marble峡谷石灰岩中描述的动物群密切相关。在这些动物群中，有代表性的Lespolina和高级类型的Yabeina，其中一些是我们的共同点。因此这些动物群可能是同一时代的。
T., M, x'rsaxccro and 1%., KANMEICA (., 1949) published a preliminary report on the couxglornerate-'beaiing Permian Kuma formation in the upper valley of the I-Iikaja inn t)ae Kuma rnassif, southern Kyushu., The present paper is a report on the details of the stratigraphy izxcludingremarlcs on fusulinid fossils from the formation and discussion on the correlation abundantly with otlxer., eong1ornerate-bearing late Permian formations in the Japanese Islands., For a brief account of the stratigraphy and rock facies of the I{urna formation, the reader is requested 'to refer to the previously published paper and the columnar seat, Tons in the Japanese text of the present paper., Here I will present an outline of the fusulinid faunule., In the Kuma formation, lintestones occur at four horinzons and contain abundantly fusulinid'fossils as indicated in the columnar sections., In the faunale, the most diagnostic members, jlnich are predominant in every horizon, are five species of Yaoeina, and Lepidolina., All the species of Yabeina are of much more advanced type than Yabeina, globosa (YABE)(=Y., inouyei DEPRAT) and Y., katoi OZAWA., The last two are characteristic elements of the Yabeina globosa zone, which has hitherto been recognized as the youngest fuslinid zone in Japan., The assemblage of fusulinids from the Kuma formation represents a biologic group not previously recorded from Japan, and is markedly different from the faunule of the Yabeina globosa zone., The faunule of the Yabeina globosa zone is widespread in Japan and always contains certain species of Neoschwagerina, while in the Kuma formation neither remains of the Neoschwagerina nor species common to the faunule of the Yabeina globosa zone have been found., In the Kuma massif the Yabeina globosa zone is exposed in a locality somewhat separated from the area of the Kuma formation, and, accordingly, the stratigraphic relationship is hardly determine in the field., However, the faunule of the Kuma formation is entirely different from that of the zone of Yabeina globosa and is biologically more advanced than the latter., The late Permian formations which can be correlated with the Kuma formation are widely distributed in a number of separated areas in the Japanese Islands., For example, they are the Mizukoshi formation (T., MATUMOTO and H., HUZIMOTO) in central Kyushu, the Shiraiwa formation (R., T0RIYAMA, the upper part of the Tsunemori group of M., KATAYAMA) in Yamaguchi prefecture, the Nukada and Maizuru formations (K., NAKAZAWA) in Koyto prefecture, the Yasuba type limestone conglomerates (with fusulinids in the matrix) of the Yasuba and other areas (R., TORIYAMA) in Kochi prefecture and of Dodo (K., K0NISHI) in Okayama prefecture, and the Toyoma formation (M., MINATO) in the Kitakami massif., These formations generally consist chiefly of black shale, sandstone, remarkable conglomerate, and subordinataly intercalated small limestone, lenses., The conglomerate contains boulders, cobbles and pebbles of granitic and various other igneous rocks., In the limestones Yabeina shiraiwensis OZAWA, Y., yasubaensis, TORIYAMA, Lepidolina kumaensis KANMERA (MS) L., toriyamai KANMERA (MS) and other closely related forms are contained., From these facts I have arrived at the conclusion that the faunules of the Kuma formation and other conglomerate-bearing formations mentioned above constitute the zone of Lepidolina (or the upper zone of Yabeina), which is distinguished from the zone of Yabeina globosa., The faunule of the Kuma formation is closely related in specific composition to the faunule described by GUBLER (1935) from Cambodge of Indochina and to that described by THOMPSON and WHEELER (1942, 1948) from the Marble Canyon limestone of British Columbia., In these faunules representatives of Lepidolina and the advanced type of Yabeina are present and some of them are common to ours., Therefore these faunules are probably of the same age.,
