Nassarius siquijorensis (A. Adams, 1852) and N. crenelliferus (A. Adams, 1852), two similar and often misidentified species (Gastropoda: Nassariidae)

In 1984 W.O. Cernohorsky reviewed the Indo-West Pacific species of Nassariidae. He revised Nassarius siquijorensis (A. Adams, 1852) and among the many synonyms listed were N. crenelliferus (A. Adams, 1852) and N. cingendus (Marrat, 1880). In this paper N. crenelliferus is considered to be a valid species and N. cingendus a synonym of this species, not a synonym of N. siquijorensis. Nassarius siquijorensis remains a valid species and its type location is designated.
