To investigate the phylogeny of Patellogastropoda, the complete 18S rDNA sequences of nine patellogastropod limpets Cymbula canescens (Gmelin, 1791), Helcion dunkeri (Krauss, 1848), Patella rustica Linnaeus, 1758, Cellana toreuma (Reeve, 1855), Cellana nigrolineata (Reeve, 1854), Nacella magellanica Gmelin, 1791, Nipponacmea concinna (Lischke, 1870), Niveotectura pallida (Gould, 1859), and Lottia dorsuosa Gould, 1859 were determined. These sequences were then analyzed along with the published 18S rDNA sequences of 35 gastropods, one bivalve, and one chiton species. Phylogenetic trees were constructed by maximum parsimony, maximum likelihood, and Bayesian inference. The results of our 18S rDNA sequence analysis strongly support the monophyly of Patellogastropoda and the existence of three subgroups. Of these, two subgroups, the Patelloidea and Acmaeoidea, are closely related, with branching patterns that can be summarized as [(Cymbula + Helcion) + Patella] and [(Nipponacmea + Lottia) + Niveotectura]. The remaining subgroup, Nacelloidea, emerges as basal and paraphyletic, while its genus Cellana is monophyletic. Our analysis also indicates that the Patellogastropoda have a sister relationship with the order Cocculiniformia within the Gastropoda.

Morphological aspects of the eggs and egg capsules of the neptune whelk, Neptunea constricta (Dall, 1907) (Mollusca: Gastropoda: Buccinidae) are described and illustrated with capsular dimension and enumerations of eggs and egg capsules based on the specimens collected from continental shelf of East Sea, Korea.

Complete 18S rDNA sequences were determined for 10 vetigastropods in order to investigate the phylogeny of Vetigastropoda, which is controversial. These sequences were analyzed together with published sequences for nine other vetigastropods and two nerites. With the two nerites as outgroups, the phylogeny was inferred by three analytical methods, neighbor-joining, maximum likelihood, and maximum parsimony. The 18S rDNA sequence data support the monophyly of four vetigastropod superfamilies, the Pleurotomarioidea, the Fissurelloidea, the Haliotoidea, and the Trochoidea. The present results yield the new branching order: (Pleurotomarioidea (Fissurelloidea ((Scissurelloidea, Lepetodriloidea) (Haliotoidea, Trochoidea)))) within the vetigastropod clade.

최근 15년동안 전국에서 채집된 청자고둥상과를 동정, 분류하였다. 지금까지 기록된 한국산 청자고둥상과는 33종으로 본 연구에서 다음의 한국미기록 7종을 추가하였다. Etrema (Etremopa) streptonotus(Pilsbry, 1904), Pseudoetrema fortilirata (Smith, 1879), Mangelia(Guraleus) deshayesii (Dunker, 1860), Philbertia (Kermia) tokyoensis(Pilsbry, 1895), conus Capitanellus Fulton, 1938, Conus 림퍄연 Lama가, 1810, Terebra Lima Deshayes, 1857. 이로써 한국산청자고둥상과는 총 3과 21속 40종이 기록된다.

Cerithiid specimens collected in South Korean waters (12 localities) during the period from August 1965 to October 1991 were identified and classified. In the present study, seven species in six genera were identified as Korean Cerithiidae. Among them, three species, Blttlum variegatum Kuroda and Habe, 1971, Brttrum cratlculatum Gould, 1860 and Ataxocerlthlum abnormale (Sowerby, 1903), are new to Korean malacofauna and fully redescribed with illustrations.

Up until now, we have identified 17 exotic species of Mollusca in Korea. These include Achatina (Lissachatina) fulica, Limax flavus, Limax marginatus, Deroceras reticulatum, Hawaiia minuscula, Zonitoides yessoensis, Zonitoides arboreus, Physa acuta, Pomacea canaliculata, Pomacea insularus, Crepidula (Crepidula) onyx, Mytilus galloprovincialis, Xenotrobus securis, Perna viridis, Argopecten irradians irradians, Pinctada fucata, and Pinctada margaritifera. Among them Achatina (Lissachatina) fulica, Pomacea canaliculata, Pomacea insularus, Argopecten irradians irradians, Pinctada fucata, and Pinctada margaritifera were intentionally introduced, whereas remainings were unintentionally introduced into Korean fauna. These foreign species can be divided into three groups on the basis of their habitats: A. fulica, L. flavus, L. marginatus, D. reticulatum, H. minuscula, Z. yessoensis, and Z. arboreus in terrestrial habitat; P. acuta, P. canaliculata, and P. insularus in fresh water; and C. onyx, M. galloprovincialis, L. fortuneikikuchii, P. viridis, A. irradiansirradians, P. fucata, and P. margaritifera in sea water. Taxanomically, 11 species belong to Gastropoda, whereas 6 species are classified to Bivalvia.

Sex ratio of a population is a key factor to determine reproductive rate of the population. If the population has skewed sex ratio to the male, the population size may decline gradually at an area which it inhabits, and, furthermore, if a species plays an ecologically important role in its community (e.g., a keystone species in Paine, 1966), its potential reproductive rate will be to form a characterized community because community structure is strongly influenced by the abundance of the ecologically important species (Hughes, 1986). A number of workers (e.g., Bryan et al., 1986 in Nucella lapillus; Spence et al., 1990 in Thais haemastoma) suggested that high frequency and/or late stage of imposex might affect the female mortality and normal reproduction adversely. Consequently, the imposex could affect sex ratio of natural population of some neogastropod including thaisid species. (omitted)
