1.Studies on Parafossarulus manchouricus Bourguigant in Korea.
The Korean Journal of Parasitology 1964;2(1):27-34
A snail of the primary host of Clonorchis sinensis, distributed in the Korean Penninsula, has been called Bulimus striatulus (Benson) Shiba 1934, while that of China, the mainland of Asia, and of Japan has been called Parafossarulus manchouricus Bourguigant(Abbott l951, Sugihara l954). Having studied on the external character and radula of the snail collected from nine areas of Korea, including Kimhae, Jinyong, Namji, Ulsan, Kunsan etc.The author has not found any reasonable distinctions which set up different species between Korean species and Chinese or Japanese species although there exists some slight difference.

2.Classification of Planorbidae cellected from Geum river basin.
The Korean Journal of Parasitology 1983;21(1):118-124
The distribution, external morphology, radula, chromosome numbers of Planorbidae snails were studied. The specimens were collected at four stations in Nonsangun, Kongjugun, and Daedukgun which are located around Geum river. Three genera and three species of Planorbidae, Hippeutis cantori, Segmentina hemisphaerula and Gyraulus convexiusculus, were collected. H. cantori was the most abundant species among the three species. G. convexiusculus was the least abundant one. Each species could be identified on the basis of its external characteristic, since the periphery of each species has a peculiar shape. H. cantori was the largest one among the three species. The radula formula of each species was very similar to other species. The size of radula was proportional to the size of shell. The radula formulae of H. cantori, S. hemisphaerula, and G. convexiusculus were 29:1:29, 23:l:23, and 16:1:16 respectively. The difference of radula formula could be found in the total numbers of laternal and marginal teeth. The haploid chromosome number of H. cantori was eighteen (n=18). S. hemisphaerula and G. convexiusculus were assumed to be same in their chromosome numbers (n=18).
