The life history of Oxidus gracilis was observed at Niihama district (Ehime Prefecture, Japan) during the year 1959 and 1961. The results were as follows: 1. The animals pass through seven larval stadia and sexual maturity occurs in the eighth stadium. Sex differentiation takes place in the larvae of the fourth stadium. Male animals develop a pair of very minute gonopod-bud appears at the position where the eighth legs had grown in the former stadia. The gonopod-bud scarcely grows during the stadia from the fifth to the seventh. However, it changes abruptly to a pair of complete gonopods at the eighth stadium. 2. The animals may be divided into two strains according to their breeding season. a) Strain breeding in Spring: The adults begin to crawl out of hibernation in early spring, and lay eggs from April to May. The larvae of this strain become adult at the end of November and then hibernate. b) Strain breeding in Autumn: The animals hibernate at various larval stadia as the fifth, the sixth or the seventh, and become mature in the early summer of the nest year, and lay eggs in autumn.

The vertical distribution of freshwater planarians in the Nikko National Park in the northern part of the Kanto Region, Honshu (Lat. 36°40'N. to Lat. 37°00'N. and Long.139°10'E. to Long. 139°40'E.), is reported in the present paper. The park is characterized by volcanoes of the Nasu Volcanic Zone (Mt. Nantai, Mt. Shirane, etc.) and many volcanic lakes (Lake Chuzenji-ko, Lake Sai-no-umi, Lake Yu-no-umi, Lake Suga-numa, Lake Maru-numa, etc.). The highest peak, Mt. Shirane (2578M above sea level), is located at the central part of the park. The main river systems in the park are the Daiya (the upper tributary of the Kinu River), the Kinu, the Katashina (the upper part of the Tone River) and the Tadami (the upper part of the Aga River). The Oze-ga-hara Moor is situated at the north-western corner of the park (Lake Oze-numa is located at an elevation of 1665M). The survey of the Daiya River system (the altitude range from 530 to 2024M) was made in August-September, 1968. Three species of freshwater planarians, Dugesia japonica Ichikawa et Kawakatsu, Phagocata vivida (Ijima et Kaburaki) and Polycelis auriculata Ijima et Kaburaki, were found in the area surveyed. These three species were also recorded by Kaburaki (1922 a, b, 1936) and Ueno (1934) from the same river system. Kaburaki (op. cit.) recorded Bdellocephala brunnea Ijima et Kaburaki in the vicinity of Nikko City. In the Oze-ga-hara Moor, Ph. vivida was collected by Kawai (in litt. and 1954). As far as our present knowledge goes, the altitude of the upper limit of distribution of D. japonica (J) was about 1460 metres (the vicinity of Yumoto Hot Spring; cf. Kaburaki 1922 a, b). Ph. vivida (V) was recorded in the stations within the altitude range from about 950 to 1460 metres. Pol. auriculata (A) was recorded in the cold-water stations within the altitude range from about 930 to 1660 metres. The type of the vertical distribution in the park is shown as J-JVA-A. This type belongs to the original type J-JV-JVA-VA-A found in North Honshu (cf. Kawakatsu 1965, 1967).

近來樺太島就中南部樺太地方の昆虫相に注目する人士輩出し該島の昆虫相目を追ふて闡明せられつヽあるは寔に喜ぶ可きである。特に蝶類相に至っては可なりな進歩を見せてゐる。然し乍ら他の目の昆虫相となると未だ未だ暗黒の状態を脱し得ない、曾て松村博士の發表された「樺太昆虫相の第一貢獻」なる論文は此暗黒界に向つて投ぜられた暁の第一線であった。然して該島のハネカクシ相に至っては松村博士の報告に發表された十種以外には全く不明である。私が今から記さうとするのは南樺太産ハネカクシの一部で大正十二、十三、兩年、鹿野忠雄君の採集品である。種數僅かに七族十二属二十三種所謂大海の一滴に過ぎないが、珍しい者新しい者も多少含んで居る故該島の昆虫相の知識に對する、一貢獻として茲に發表する事とした。
