REMARKS

Although common and widely distributed in the western Pacific (Davidson 1887; Thomson 1918, 1927; Dall 1920; Jackson & Stiasny 1937; Hatai 1940; Richardson 1973a, b, 1979; Zezina 1985; Emig 1987; d’Hondt 1987; Saito 1996; Laurin 1997; Bitner 2006a, c), Frenulina sanguinolenta is rare in the material from Fiji, and has been found only in seven stations (see also Bitner 2006b). It is an easily recognisable species by its small, sulcate shell and red colour pattern.
