  • Examining the polychaetous annelids collected from the Yellow $Sea(30^{\circ}20'\;N\;Lat.\;124^{\circ}35'\;E\;Long)$ Jinhae Bay, Yeocheon Bay, Jeju Do and Weolpo. I found five species which should be added in the list as new to the polychaetous annelids fauna of Korea. In the present study five species are reported morphological descriptions. Consquently, a total 125 species of polychaetous has been reported(Kamita and Sato 1941; Paik 1972, 1973a, 1973b, 1975a, 1975b, 1976, 1977, 1978, 1979; Lee 1976; Rho and Song 1974, 1975) in Korea.

  • Aquatic Oligochaeta is a notable animal group in freshwater environment such as streams, rivers and lakes in view of its biomass and species richness. Taxonomic studies of this group, however, have hardly been performed in Korea. Here five naidid oligochaete species are reported - Slavina appendiculata, Pristina longiseta, Pristina biserrata, Chaetogaster diaphanus and Nais variabilis - from the Seokhyeoncheon Stream in Yangju and from the Changreungcheon Stream in Goyang, Gyeonggi-do. Aquatic oligochaetes attaching on aquatic vegetations were collected with a plankton hand net. An image and description on Nais variabilis new to Korea are provided.

유기성 슬러지 급이에 따른 크롬과 망간의 줄지렁이 (Eisenia andrei (Annelida; Oligochaeta)) 체내 생물축적 (Bioaccumulation of Chromium and Manganese in the Earthworm Eisenia andrei (Annelida; Oligochaeta) in Relation to the Supply of Organic Sludges)

  • 경기도 포천시 하수처리장에서 수처리후 탈수된 몇 가지 유기성 슬러지내 크롬과 망간 농도에 대하여 조사하였다. 또한, 슬러지 급이량 변화에 따른 줄지렁이(Eisenia fetida) 체내 크롬과 망간의 생물축적에 대하여 고찰하였다. 유기성 슬러지내의 크롬과 망간 농도는 각각 0.0~0.3 mg/kg, 3.6~17.6 mg/kg를 나타내었기에, 이러한 중금속 농도들은 지렁이 개체군에 대하여 급성독성을 유발시키지 않는 것으로 판단되었다. 그리고, 슬러지 급이량 증가에 의하여 지렁이 체내에 크롬의 생물축적이 이루어졌으나 슬러지 공급량에 비례해서 크롬 농도가 증가하지 않았으며, 일정한 농도로 유지되다가 감소하는 경향을 나타내었다. 한편, 망간에 대해서는 생물축적이 거의 일어나지 않았다. 본 실험으로부터 60 g의 슬러지를 공급하였을 때, BAF 값은 망간의 경우 0.00~0.12이었으며, 인분슬러지를 주입하였을 때 BAF 값은 크롬의 롬 경우 19.33를 나타내었다.

  • Two newly recorded opheliid polychaetes, Armandia amakusaensis Saito, Tamaki and Imajima, 2000 and Polyophthalmus qingdaoensis Purschke, Ding and $M{\ddot{u}}ller$, 1995, from Korean waters are reported with the descriptions and illustrations. Armandia amakusaensis can be clearly distinguished from its congeners by the following characteristics: the prostomium has 2 or 3 subdermal eyespots; total number of setigers are 29; the branchiae are present on the setigers from the setiger 2 to the second or third from the last setiger; the lateral eyespots beginning from the setiger 7 are composed of 11 pairs; the anal funnel has 8~11 papillae and a long cirrus. Polyophthalmus qingdaoensis has the distinguishable characteristics from its relatives as follows: the prostomium has a brain bearing dark pigment-spots; the lateral eyespots are distinct; the body has only dark pigment-streaks on dorsal side. We also provide the keys for distinguishing the species of the genera Armandia and Polyophthalmus from Korean waters.

  • The genera Dero and Allonais belong to the family Naididae. Most species in the genus Dero have unique morphological characters including a branchial fossa and/or gills at the posterior end of the body. The genus Allonais has no eyes unlike its close relative the genus Nais. Of these genera, one species of Dero, D. obtusa, was recently reported in Korea. However, the genus Allonais has not been recorded in Korea. Here, we report Dero dorsalis Ferroni$\grave{e}$re, 1899 and Allonais pectinata (Stephenson, 1910) with a diagnosis and illustrations.

  • Tubificid oligochaetes are common and frequently dominant in freshwater benthic habitats. They are so tolerant to water pollution that they are often used as biological indicators. Faunistic studies of Korean freshwater oligochaetes have been actively conducted recently. The most well studied oligochaete family in Korea is the tubificids following the naidids. Nine species of tubificids have been reported so far. Nevertheless, many species of tubificids still remain to be discovered in Korea. In this study, we added four species of tubificid oligochaetes to the Korean fauna, including Linmodrilus profundicola (Verrill, 1871), Potamothrix heuscheri (Bretscher, 1900), Tubifex blanchardi $Vejdovsk\acute{y}$, 1891, and Ilyodrilus templetoni (Southern, 1909) based on specimens collected from three locations in Korea: Cheonan-si, Geoje-si, and Seocheon-gun. In particular, P. heuscheri was first reported in Asia.

  • An aquatic oligochaete species, $Ripistes$ $parasita$ (Schmidt, 1847) collected from Ganghwado Island in Korea, is described and illustrated. Specimens inhabiting on aquatic vegetation at the edge of the streams were collected with a plankton hand net. Morphological features of present specimens such as the number of long hair chaetae per bundle and their length in VI-VIII, and shape and size of ventral chaetae are concordant with those of previous reports on this species. The genus $Ripistes$ contains one species, $R.$ $parasite$ which is distributed over, Europe, North America and eastern part of Asia including China and Japan. This is the first record of $R.$ $parasita$ in Korea.
