If a specialist, especially someone belonging to a university, visits a high school or a school of lower stage and gives lectures about his or her specialty, such lectures (or such an acitivity) are called delivery-lectures. Although a high school-college collaboration, especially the deliverylectures, is spreading rapidly in Japan, learning in such a collaboration tends to be one-way from college to high school. To make it supply effects in the opposite direction, we took up deliverylectures designed and performed not by professors but by graduate students. During the activities, the graduate students realized that they got some educational effects such as expanding of their horizons, getting teacher’s mind, understanding the diffi culty of teaching and behaving in a positive attitude. The high school students considered that the lectures were benefi cial and the graduate students had enough ability to teach. These results suggest that delivery-lectures by graduate students are available as two-way learning between high schools and colleges.

Hynobius takedai was observed in the breeding season at Joyama in the city of Toyama in 1983. Measurements of five dimensions i. e., head width, head length, snout-vent length, tail length, and maximum tail height, were taken and the males were also individually marked. Twenty males and eighteen females appeared at the breeding site, and five of the males succeeded in protecting their territories. The males with territories (MTs) appeared earlier in the water than the males without territories (non-MTs). The males with larger bodies succeeded in protecting their territories and inseminating, since they were dominant in the struggle among fellow males. The snout-vent length of the MTs was more than 50mm, and their heads were wider than those of the non-MTs. The longer the snout-vent length of the MTs was, the larger their head and tail were, compared with those of the non-MTs and the females. The heads of the MTs grew larger and their tails grew longer only during the breeding season.
