    Recent expeditions to the China Seas and off Taiwan have resulted in new geographical extensions and new species discoveries in the Muricidae: Abyssotrophon weijencheni n. sp. and Enixotrophon petalospeira n. sp. (Pagodulinae), Scabrotrophon fedosovi n. sp. (Trophoninae) and Siphonochelus hasegawai Houart, Buge & Zuccon, 2021 (Typhinae). A distribution map for each listed species completes the information. Additional information is given for Enixotrophon ziczac (Tiba, 1981) from Japan, not collected during these expeditions but compared with one of the new species described herein.

    Host species for the glochidia of the freshwater unionid mussel Buldowskia iwakawai (Suzuki, 1939) from Hokkaido were identified by determining whether the glochidia infected seventeen fish taxa in winter. The fishes were kept in tanks for 11–15 days after glochidial infection, and the number of glochidia and metamorphosed juveniles detached from the hosts were counted. Living juveniles of B. iwakawai detached from Opsariichthys platypus, Candidia temminckii, Pseudaspius hakonensis, Phoximus lagowskii steindachneri, Lefua echigonia, Poecilia reticulata, Eleotris oxycephala, Odontobutis obscura, Tridentiger brevispinis, Rhinogobius nagoyae and Rhinogobius similis. Therefore, these eleven fishes were identified as suitable host species for the glochidia of B. iwakawai.
