摘要

This paper describes a new species of the family Nassariidae, Nassarius glabrus sp. nov., from the South China Sea, and the East China Sea. The new species is characterised by its glossy and smooth shell surface with longitudinal ribs on only the first 2-4 postnuclear whorls, its light brown colour with sparse yellowish-brown blotches, its deep suture and prominent shoulder. The new species inhabits sandy or muddy-sand sediments at depths of 110-280 m.
