The Funabuseyama Limestone, an exotic limestone block in the western part of the Jurassic Mino Terrane, yields various kinds of Permian foraminifers especially fusulines ranging from the Artinskian to Capitanian. Many microphotographs of fusuline and non-fusuline foraminifers are illustrated to reconsider the foraminiferal information of the Funabuseyama faunas and to compare with the coeval faunas in and outside of Japan. Thirty-one species of Middle Permian fusulines are systematically described. Fusuline faunas in the Mino Terrane, characterized by the component of Acervoschwagerina, Parafusulina japonica, and Yabeina, are similar to most of those in other Jurassic terranes of Japan, but different from those of the Permian terranes of Japan where these three taxa are almost absent.

The authors conducted the petrologic descriptions and magnetic susceptibility assessments of the Sekinomiya peridotite body and the early and late modern stone works located in the northern Hyogo Prefecture, Southwest Japan. The stone works made of serpentinite, such as lanterns and guardian dogs, were produced between the late Edo and early Showa periods (the 1830s–1930s). Based on the magnetic susceptibility values, serpentinite exposures of the peridotite body were classified into three groups: H, M and L. The lanterns were carved from the serpentinite stone related to the M group. Distribution of the M group serpentinite exposures in the Sekinomiya peridotite body suggests that most of the stone materials have been collected at the sites along the Soji River in Sekinomiya, and the Kabosaka and Otani rivers in Oya, Yabu City.

Batrachospermum beraense Kumano (Batrachospermaceae, Rhodophyta) is reported for the first time from Sabah, North Borneo, Malaysia. B. beraense from Sabah is characterized by the following combination of features: (i) olive green to blue-green monoecious or dioecious plants that are 2–7 cm high with a diameter of 300–590 μm, more or less dichotomously branched, and mucilaginous; (ii) laterally branched primary fascicles consisting of 7–18 cell-storeys; cylindrical or ellipsoidal fascicle cells that are 4.6–6.1 μm in diameter and 15–30 μm long with numerous short and long terminal hairs; (iii) spherical spermatangia that are 4–7 μm in diameter and are either terminal or subterminal on fascicles; (iv) straight carpogonium-bearing branches, differentiated from fascicles, that are 72–125 μm long, consisting of 8–14 cells, arising from a pericentral cell; (v) ovoidal and indistinctly stalked trichogyne; (vi) single, axial, and spherical to ellipsoidal carposporophytes that are 63–120 μm in diameter and obovoidal carposporangia that are 7.7–11 μm in diameter and 12–18 μm long.

Cymothoa pulchra (Crustacea: Isopoda: Cymothoidae) was collected from the Japanese parrotfish Calotomus japonicus (Perciformes: Scaridae) at Izu Oshima Island, Tokyo, Japan. Ovigerous females of C. pulchra were collected from the Japanese parrotfish, indicating that C. pulchra actually are able to parasitize and to actually breed on Japanese parrotfish.

Phenological observations were performed monthly for 28 coastal plant species between April 2015 and February 2017 in the coastal part of Kyotango City, located in the eastern part of the San’in coast, western Japan. According to their habitats, the coastal plant species observed were classified into three types: the beach-dune type (Carex fibrillosa, Carex kobomugi, Carex pumila, Fimbristylis sericea, Ischaemum anthephoroides, Zoysia macrostachya, Lathyrus japonicus, Viola grayi, Viola mandshurica f. crassa, Arabis stelleri var. japonica, Salsola komarovii, Tetragonia tetragonoides, Heliotropium japonicum, Calystegia soldanella, Linaria japonica, Scutellaria strigillosa, Orobanche coerulescens, Aster arenarius, Ixeris repens, Melanthera prostrata, Cnidium japonicum, Glehnia littoralis, Juniperus conferta, Vitex rotundifolia), the rocky coast type (Sedum japonicum subsp. oryzifolium var. oryzifolium, Lysimachia mauritiana), and the grassland-bush type (Veronica ornata, Angelica japonica). The time and duration of leafing, flowering, and seed dispersion were summarized for each species.
