New Buccinid and Turrid Gastropods from North Fiji and Lau Basins

Abstract

Both Eosipho boucheti n. sp. and Phymorhynchus wareni n. sp. were collected from North Fiji Basin and Lau Basin where active hydrothermal vents exist. The former species are so abundant that it is hardly a mere guest species to the vent areas but has a certain relation to the vent biocommunity, while the latter may be a guest which may live in non-vent areas as well.
