  • This paper is examine the mutagenic activities of the water samples from Chun-gye and Joong-rang streams in March, 1968. For this examination, adsorbed of mutagens by 'blue cotton' and Ames method using Salmonella typhimurium was used. The results were as follow; 1. The average revertant colonies of the Chun-gye stream on TA 98 was 120/plate and TA 100 was 267/plate. 2. The average revertant colonies of the Joong-rang stream on TA 98 was l06/plate and TA 100 was 407/plate. 3. Chun-gye and Joong-range streams showed about the same mutagenic activities. 4. The mutagenic activity of treated sewage was higher than of untreated sewage. It is considered that, among the influent materials with Zimpro oxidation fluid, human feces and urine increased mutagenic activities.

  • Four specimens of Chlorophthalmus albatrossis Jordan and Starks and one specimen of Chlorophthalmus acutifrons Hiyama belonging to the family Chlorophthalmidae were collected for the first time from Korea. We propose "Pa-rang-nun-mae-tung-yi" for Chlorophthalmus albatrossis and "Ch$\breve{u}$m-mun-pa-rang-nun-mae-tung-yi" for Chlorophthalmus acutifrons as a new Korean name.
