作者在一九八四年七月間前往蘭嶼,趁進行全島寄生蟲防治工作之便,作醫學貝類調查。由十七個不同的地區採集得一千四百餘枚淡水及陸生腹足綱的軟體動物,經分類鑑定之結果顯示,該島計有淡水貝十二種及陸生貝五種。本文並討論其分佈、生態環境、及其與寄生蟲病之關係。
A survey and collection of freshwater and land snails were conducted in July 1984 on Lan-yu island. More than 1,400 snails were collected from 17 different foci. They were preserved and carefully classified. A total of twelve species of freshwater snails and five species of land snails were found. Their distributions, habitats, and relationships to parasitic diseases are discussed.
