On some Fusinus from the East and South China Seas (Mollusca: Gastropoda: Fasciolariidae), with description of a new species

摘要

Four species in the fasciolariid genus Fusinus obtained by Chinese commercial fishing boats are identified and compared with material from the Philippines and Japan. One is here described as new to science, Fusinus marisinicus n. sp. Phenotypic variation in Fusinus salisburyi, F. forceps and F. diandraensis is discussed, and various forms are figured with their intergrades. Further descriptive details of F. diandraensis are given, and new comparisons are made with sympatric congeners including F. perplexus and F. flavieomus.
