According to Goldschmidt (1934), the Gifu-type race, the weakest race among the strong races, is known to distribute in a certain region of Japan around Gifu City. This race is characterized by producing a special type of female intersex at crossing. The larvae of this race were used as the donor of the gonadal transplants in the present experiment. The larvae of the Ha.-A strain (the weak race from Hakodate) bearing their own gonad, received a pair of larval ovaries, or testes, from the Gifu-A strain, obtained from Gifu City, at their 4th instar stage (see Tables 1 and 2). The hosts were furnished for observations of their sex-characters under the effect of the grafts. It was found that the gonadal transplants carried out in this experiment were without effect on the sex-characters of the hosts.
