Subfamily Buccininae Rafinesque, 1815 Diagnosis: Shell small to large (over 150 mm), oval to broadly fusiform, without siphonal canal and with siphonal notch. Protoconch paucispiral. Whorls convex to (sub)cylindrical, shouldered, sometimes with strong keel at shoulder. Shell sculpture pronounced in most cases, spiral sculpture from microscopic threads to prominent keels; axial sculpture, when present, of distinct, broad, sigmoid or arcuated axial ribs. Shell covered with ciliated periostracum, sometimes thick and forming lamellae. Aperture wide, ovate with simple outer lip. Operculum small to large, with subcentral nucleus. Radula with central tooth with broad rectangular base, notched anteriorly, and with nearly straight posterior margin with three to eight cusps; lateral teeth with three to four cusps, intermediate one much shorter than outer and inner ones (after Kantor et al . 2022). Remarks: This family is only partially treated in this report. Only two very distinctive new genera and a few of the more remarkable new species are described. A more comprehensive study of this subfamily from the Aleutians is in progress. In The Aleutian Islands 26 species in four genera are recognized, including two new genus and seven new species. Additionally, at least seven more as yet undescribed species are known from the Aleutians, but are the subject of another report.
