In a recent paper, the writer established a new stromatoporoid, Labechiellata based upon Labechiellata regularis from the Middle Gotlandian deposits of the Kitakami Mountainland. Besides the genotype, it has only two species Labechiellata mingshankouensis (OZAKI) and Labechiellata sp., from the Ordovician limestone of South Manchuria and Shantung, both being at first identified by K. OZAKI to be belonging to Actinostroma.
Recently the writer received a very good specimen of the genus Labechiellata from Mr. T. OHSE of the Tyosen Muentan Kabusiki Kaisya, who collected it from the Middle Ordovician limestone developed at Tyozyori, Nikkamen, Tokusen-gun, Heian-Nanthi, Tyosen. Examination of the form of Labechiellata soon reveals it to be quite identical with Labechiellata sp. mentioned above, to this fossil being given the name ohsei in honour of T. OHSE.
Consequently the distribution of Labechiellata is now known to extend from Shantung, China to South Manchuria into North TyOsen and to the Kitakami Mountainland of North Japan.

Since the publication of our article entitled, “The Recent Brachiopod Fauna of Japan.(3) Notes on the Subfamily Laqueinae, ” published in Proceedings of the Imperial Academy, Vol.11, pp.44-46, 1936, several interesting species of the genus Pictothyris have recently accumulated through the efforts of Dr. S. ENDO of our Institute. Among the recently obtained materials there were found one new species and one new subspecies of Pictothyris, and in this note we wish to describe them.
The fossils were collected by Dr. S. ENDO from two localities, viz., Kuwanomaru and Unoki, both in Yosida-mura, Kagosifma. gun, Kagosima-ken, Kyusyu, not. far distant from the city of Kagosima. Belonging to the same stratigraphic horizon, the brachiopods were found in association with a large number of shells of molluscs and balanids, besides there are also some of solitary corals and bryozoa. The molluscan fossils will be treated with in another article. According to S. ENDO the fossils were derived from the following stratigraphic position, namely.

The fossil molluscs dealt with in this article were collected by Dr. S. ENDO of our Institute during his trip for collecting fossil plants. Although only two localities belonging to the same stratigraphical position are listed, the fauna is particularly interesting as it contains elements characteristic of certain Pleistocene deposits of Japan, . as to be stated later.
Here we wish to record our. thanks to Dr. S. ENDO for offering the fossils to our study.

The writer as a result of his studies on the stratigraphy of the Tertiary deposits, developed in the region extending from Isipomori-mati, Tome-gun, Miyagiken at the south, to the Koromo-gawa, Iwate-ken at the north, recognized the following stratigraphical order of the different rocks, namely.

In his “Hokkaid Tisitu Ryakuron (Geological Sketch of Hokkaid) ” in 1890, Kotora Jamo has illustrated three non-marine fossil shells from the Sorati coal-field, Province of Isikari, Hokkaia, and they were Paludina sp., Anodonta sp. and Cyrena sp. These three shells were also listed in his Explanatory Text to the Geological Map of Hokkaidt. Unfortunately, however, their exact for mations and localities were not mentioned in these publications. Judging from the general stratigraphy of the Sorati coal-field it is presumable that these shells were obtained from certain horizons in the Oligocene Isikari series. Examining the original specimens of JIMBO's Paludina sp. and Anodonta sp., stored in our Geological Institute, Faculty of Science, Imperial University of Tokyo, the conclusion that the former is a new species of Viviparus, for which V. jimboi is proposed here, and the latter is a varietal form of Margaritifera Perdahurica (YOKOYAMA). Although the original specimen of JIMBO's Cyrena sp. could not be, found in the Institute collections, it is found that his illustration best agrees with the high, subtrigonal form of Corbicula atrata tokudai (YOKOYAMA) The writer's heartiest thanks are due to Prof. Teiichi KOBAYASHI of the Geological Institute, Faculty of Science, Imperial University of Tokyo, for looking through the manuscript of this short paper.

Last summer Mr. Michio KAWATA sent to Prof. T. KOBAYASHI two thin sections of fusulinid limestone obtained at Shi-huei-yao-tzu, Ta-wei-chia-tunn, Chin-chou district, Kuangtung province. According to K AWATA'S observation at the locality, the Tonfangiae limestone is overlain by a fine clay bed 4.5m. paraconformably. The bed is followed upward by a yellowish shale bed 17m. thick, a limestone layer 1.5m. thick and a sandy shale formation. The thin sections of the limestons was kindly transferred me for study.

During their survey of the Sosan area in 1931 Prof. T. KOBAYASHI and Mr. Shoen KIN discovered a small lens of dark grey “Staffella” limestone on the northeastern road-side of Shinmaliudo, Nanmen, Sosan-gun, North Heian-DO.
The limestone-bearing formation lies on the Toufangian limestone disconformably on the west side and is cut by faults on its northeast and southeast sides. It occupies a small area within the Cambro-Ordovician terrain and consisits of the lower part of fine purple shale and the upper of reddish purple sandstone, and the fossiliferous limestone-lens is found near the top. Finding the primitive fusulinids in the limestone, they referred this thin formation (some 30m. thick) to the lower part of the Koten Series.
By courtesy of Prof. Teiichi KOBAYASHI of the Geological Institute, Imperial University of Tokyo, I had an opportunity of studying his thin sections of the limestone during my stay at the Institute in this summer.
Here I wish to express my most sincere gratitude to Prof. KOBAYASHI for his valuable suggestion given to me in his laboratory. My best thanks are also due to Prof. Haruyosi HUZIMOTO of the Higher Normal School of Tokyo for his kind advices on my palaeontological study.
