On the Genus Fusinus in Japan III : Nine Further Species, with Type Selections

Abstract

In the third in a series of papers, a further nine valid species of the fasciolariid genus Fusinus occurring in Japanese waters are examined: F. akitai Kuroda & Habe, 1961, F. colus (Linnaeus, 1758), F. crassiplicatus Kira, 1959, F. gemmuliferus Kira, 1959, F. nodosoplicatus (Dunker, 1867), F. penioniformis Habe, 1970, F. tuberosus (Reeve, 1847), F. nigrirostratus E. A. Smith, 1879 and F. nicobaricus (Roding, 1798). Fusinus grabaui Kuroda & Habe, 1952 is placed in the synonymy of F. nodosoplicatus Dunker, 1867, and F. sagamiensis Kuroda & Habe, 1971 in that of F. nigrirostratus. Lectotypes are selected for F. brenchleyi Baird, 1873 (= F. nicobaricus), F, colus, F. crassiplicatus, F. gemmuliferus, F. nicobaricus, F. nodosoplicatus, F. tuberosus and F. nigrirostratus. The type locality of F. colus is restricted to Cebu, Philippines. F. colus is shown to be represented in Japanese waters by two forms that intergrade in certain places.
