  • The Strombus Linn$\acute{e}$, 1758 is a genus of marine mollusks belonging to the class Gastropoda, and is distributed in the tropical waters of the world. Typically, the family Strombidae includes five extant genera (Strombus, Lambis, Terebellum, Tibia, and Rimella), all of which are mostly found in tropical waters. Five individuals of Strombus luhuanus Linn$\acute{e}$, 1758 were collected from Uljin, Gyeongsangbuk-do province for the first time. In this study, we describe details of shell morphology and radula characters of the species with scanning electron microscopy images of the radula. This is a new record of Strombus luhuanus Linn$\acute{e}$, 1758 from Korean waters.

  • A chromodorid nudibranch species Cadlinella subornatissima Baba, 1996 (Gastropoda: Nudibranchia: Chromodorididae) is newly recorded from Korean water. In this report, detailed external morphology is provided with its colored illustrations. This species is morphologically distinguished from other congeneric species by the following characteristics: the tip of dorsal papillae is pointed with pink pigment; yellow dorsal marking on central dorsum without mantle margin. The Korean chromodorid nudibranchs are composed of 19 species of 10 genera, including Cadlinella subornatissima which is firstly reported in the present study.

  • 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.

  • 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.

  • 큰구슬우렁이 (Glossaulax didyma)는 복족강 (Gastropoda), 중복족목(Gastropoda), 구슬우렁이과 (Naicidae)에 속하고 내만의 조간대에서 수심 10m 가까이의 진흙과 모래가 섞인 조하대애 묻혀 살며 일본과 우리나라 전역에 분포한다 (유, 1976). 큰구슬우렁이는 이매패나 복족류의 껍질에 구멍을 뚫어 섭식하는 육식성패류로 패류양식장 등의 해적생물로 알려져 있다 (유, 1976). 그러나 이들은 식용으로 이용되고 있어 지방에 따라 배꼽고둥, 배꼽, 우렁이, 잠빼기, 말띠, 미소라, 개소랑, 명지고둥, 가내기, 해구 등으로 폭넓게 불려진다. 이와 같이 식용으로 널리 이용되고 있는 큰구슬우렁이는 산업종으로 중요한 위치에 있어 자원관리적 측면에서 이들의 생식생물학적 조사가 조속히 이뤄져야 할 종이다.

  • Geographic variation in shell morphology of Thais clavigera $(K\"{u}ster)$ (Gastropoda: Muricidae) was investigated using samples collected from 24 sites along the Korean coast. Multivariate statistical analysis was applied to 9 morphometric and 4 categorical variables. The shells of T. clavigera were classified into two distinct morph types (Type-W and -E). Temperature and salinity of the sampling sites were significantly correlated with the incidence of morph types. Relative abundance of Type-W (thin, yellowish brown shell with triangular nodules) was positively correlated with temperature and negatively correlated with salinity. In contrast, relative abundance of Type-E (thick, dark purple shell with round nodules) was negatively correlated with temperature and positively correlated with salinity. Possible correlation between environmental factors (temperature and salinity) and morphological variations in the shells were discussed.
