A survey on the distribution of the fresh water snail Bithynia misella was carried out in the four river basins; Geum River, Nagdong River, Yeongsan River and Han River, from March 1980 to September 1983.
1. B. misella was collected in 19 stations(Geum River 12, Nagdong River 6 and Yeongsan River 1) out of 225 stations examined.
