A study on the distribution and community structure of the benthic molluscan shells of the southern coastral area in Cheju Island was carried out from August 1990 to July 1991. The benthic molluscan shells collected and identified from 8 stations were composed of 3 classes, 7 orders, 22 families and 59 species. The number of appearance species from station 1 to station 8 were 22, 35, 32, 26, 28, 24, 32 and 31 species respectively. the first dominant species of the upper intertidal zone of the 8 stations were Nodilittorina exigua, those of the middle zones were Monodonta neritoides from st.1 to St.5, but the second dominant species were not uniftom at ach station.
