A total of twenty six species (including 2 subspecies, and 2 varieties) of liverworts were newly confi rmed on Mt. Juwang in our survey in 2001, 2010, and 2011. All the species observed on Mt. Juwang were very common to the liverworts flora of other southern localities in South Korea.

Ecological characteristics of small Japanese flying squirrels, Pteromys momonga, such as weight, breeding seasons, development of infants, and habitat preference, were examined. The study was carried out in forests at Ashizu Valley, Tottori Prefecture, from May of 2010 to December of 2011. Twelve trees were selected in each of three study sites (10 to 20a), which were dominated by different tree species. Three nest boxes were set up on each tree at different heights above the ground (0.5m, 3m, and 6m). Observations include the following. (1) Squirrels bred at least in spring and summer. The number of young in a litter varied from one to eight. (2) The weight of adults was 100g to 170g. Female adults were heavier than male adults. (3) Squirrels almost always used the nest boxes at a height of 6m. They preferred the nest boxes in the artifi cial Japanese cedar forest near natural forests to the nest boxes in the young and matured natural forests.

Large sciaenid otoliths were presented from Narimasa Ikeda, the sixth feudal lord of the Okayama Han (clan) to Ienari Tokugawa, the eleventh Shogun of the Tokugawa Shogunate, the central government of then Japan, as one of crude medicines from 1794 to 1801, and now some of them are preserved as a historical heritage at Naito Museum of Pharmaceutical Science and Industry, Kakamigahara, Gifu Prefecture. In the preliminary survey in 2003, they were identifi ed as sagittae of Miichthys miiuy (Basilewsky) and Argyrosomus japonicus (Temminck et Schlegel) by the author, and their species names were publicly reported by Ebihara et al. 1) and Goto et al. 2) in 2004. In a follow-up survey, the author has confi rmed that the sagittae of Argyrosomus japonicus (Temminck et Schlegel) can mostly be divided into seven types (AtoG) from their polymorphic appearance. The Argyrosomus japonicus is a peculiar species: habitats of allopatric populations of this species are distributed in the East China Sea, Japan, South Africa, Pakistan, and Australia. On the other hand, the Miichthys miiuy is an endemic species which can only be seen in the East China Sea and the Yellow Sea. Although no historical record has been found as to where these two species were captured, the author surmises that the otoliths were extracted from large individuals caught in the waters of the East China Sea near the Chushan Islands (Zhoushan Qundao) where the two species inhabit together. Besides, it is conjectured that the Okayama Han, which faced the Seto Inland Sea (Setonaikai), imported Chinese otoliths through a few ports such as Nagasaki where foreign trade only with Portugal was allowed under the national isolation of the Tokugawa Shogunate.
