  • Three Ovulid species collected from Jeju Island were identified as Habuprionovolva aenigma (Azuma & Cate, 1971), Habuprionovolva basilia (Cate, 1978) and Diminovula kosugei (Cate, 1973). This is the first record from the Korean waters, providing a description of the species with illustration for the shell morphology.

  • The Turbinellidae shell Columbarium pagoda pagoda (Lesson, 1834), from the southern coast of Korea was recorded as new to the Korean molluscan fauna. The shell is typically solid and fusiform, with a well elongated spire and long anterior canal, and keel with a row developed spine. The protoconch is small, planorboid to depressed dome-shaped. The family Turbinellidae is reported from Korea for the first time.

  • Eight species of the family Bithyniidae, Bithynia tentaculata, B. leachi, B. siaminsis, B manchourica, B misella, B. kiusiuensis, Gabbia australis and a Bithynia wp. collected from Nepal, were studied for their relationship between species. Total 20 characters were employed for the principal component analysis(PCA) and taxonomic distance. G. misella and B. kiusiuensis were closely related and similar to G. australis. B. manchourica, B. tentaculata and B. siamensis relatively closed group, and taxonomic distance of B. leachi was far from the other species.

  • Inthe prisent paper, we report the study of Korean epitoniid which were collected from12 localities of Korean waters during the span of August 1982 to May 1992. Upon identification of these specimins and riview of the provious ricords, Korean Epitoniidae were found to be composed of 12 species in 10 genera, Among them, following 5 species in 4 genera were turned out to be new to the Korean malacofauna and redescribed with illustrations: Viciniscala liliputana (A. Adams, 1861), Mazescala casta(Sowerby, 1844).

  • The karyotypes of Korean endemic land snail, Koreanohadra koreana, using air-drying method wereinvestigated. Somatic cells of this species had 2n = 58. Karyotypes were also analysed with 16 metacentric, 12 submetacentric and one subtelocentric chromosome pairs. Observed chromosomes ranged from 2.6 to $8.9{\mu}m$ and the total length was $122.3{\mu}m$. This is the second report on the chromosome numbers and the karyotype of K. koreana.

  • The feeding habits of black scraper, Thamnaconus modestus, were studied using 172 specimens collected in the coastal waters of Geomun-do, Korea. The size of the specimens ranged from 16.2 to 39.1 cm in standard length (SL). T. modestus was a omnivore that consumes mainly benthos. Of the benthos species nephtheidae was the most preferred prey. Its diet also includes, algae, thoracica, gastropoda, desmospongia. Small and medium size individuals (<21~33 cm, SL) fed mainly on nephtheidae and algae. Larger individuals (>33 cm, SL) fed mainly on thoracica. The proportion of nephtheidae decreased as body size increased (>33 cm, SL), whereas the consumption of thoracica gradually increased.
