 note = {Molluscs and bottom sediments were collected by dredging in Sagami Bay off Hiratsuka in September 2018 and 2019. A total of 350 live specimens were collected, belonging to 24 species: 11 gastropods, 1 scaphopod, 11 bivalves, and 1 cephalopod. Three species (Thais clavigera , Glycymeris vestita, and Paphia amabilis ) were the first record since the dredging investigation started in 2006. All the collected species were warm-water species. The bottom sediment at depths above 5 m was composed of fine to medium sand containing 2.4-3.1% mud, and that about 10 m deep was composed of the same sand with 3.0-4.6% mud. At depths of 20, 30 and 40 m, the bottom sediments were composed of very fine to fine sand containing 4.4- 6.4, 9.9-16.4 and 15.3-24.4% mud, respectively. In comparison with the investigation results of 2018, the bottom sediments of 2019 contained more plant fragments and mud., Departmental Bulletin Paper, 短報},
