    In this paper, I concluded the followings about the geographical distribu-tion of Heptathela kimurai (Kishida) and Liphistiidae.
    (a) Northern boundary-line of H. kimurai's distribution:-
    1) Recognized that the northern boundary-line of H. kimurai's distribution coincided with the line which run through the Aso volcanic zone, and named it Aso line.
    2) Aso line is the distribution boundary-line related to the geological history and constitution, H. kimurai distributes only in south region of this line, W-S Japan Outer zone which is called in geological world.
    3) Aso line is drawned to the north of Aso-Setonaikai line (Sato, 1943) which is another distribution boundary-line connected to the same Median Dis-location Line, in this point both is dissimilar.
    (b) Southern boundary-line of H. kimurai's distribution:-
    1) The southern boundary-line of H. kimurai's distribution lies between Okinawa islands and Sakijima islands, I named Hachisuka's line to this. Hachi-suka's line is an important distribution boundary-line which will be not inferior to Watase's line.
    (c) Distribution of Liphistiidae:-
    1) Liphistiidae discontinuously distributes in the three regions, North China (Chinan), Okinawa and South Kyushu, Malay district; but this distributed widely in the East Asia before glacial epoch and this under invasion of the cold escaped to these regions and survived until to-day.
    2) These three regions, beside Liphistiidae, commonly produce Metacervulus (fossil deer), and also North China and Malay regions produce human fossils, and then I suppose regions reciprocally not only had similar character, but also kept up a convenient living environment for life in such glacial epoch.

    The centipedes brought from Torijima I. consist of two species of Lithobi-idae and one species of Henicopidae, all of which are the Holarctic elements.
    Lamyctes guamus is the first example of the genus Lamyctes found in Japan. The diagnoses of the female are as follows; Ocellus presents, large one. Anten-nae short and 27 articles in a female but about 20 in other specimens. First two articles very large in comparison with the others. Prosternal teeth 2+2. Prefensor stout. Mandible with five teeth. Tarsus of 1-12 legs simple, unarmed. Coxal pores round, small, 2, 2, 2, 2 in female instead of 1, 1, 1, 1 in male.
    Claw of gonopods in female obtuse and chitinous, basal spines 2+2, stout. Anal legs long as well as other species. Locality: Torijima I., Aug. 13, 14, 15, 1950, collected by Mr. I. Fujiyama.
    The fact that Dr. Chamberlin reported this species from Guam in 1946 is very interesting from the zoogeographical point of view, as the Lithobiid centi-pedes wwrw not expected to bew found in such an area as Micronesia, Bonin Is., etc.

    I have received seven dried specimens of scorpion through the courtesy of Mr. T. Yamané which were collected in Brazil by Mr. A. B. K. Namekata. They were the scorpions never seen by the writer and he identified them as one female and six males of Bothriurus banariensis (C. L. Koch, 1842) belonging to the family Bothriuridae. Here he describes on the above species as this Brazilian scorpion has never been treated by the Japanese zoologists.
