In a brief anatomical survey of the Tonnacea, family groups recognised are Tonnidae (subfamilies Tonninae and Oocorythinae), Ficidae, Cassidae (subfamilies Cassinae and Phaliinae), Cymatiidae (subfamilies Cymatiinae, Ranellinae, Distorsioninae) and Bursidae.
In a generic classification of the Bursidae based on opercular, penial, and stomach anatomical features, variceal position is considered to have little taxonomic significance. Genera recognised are Bursa Röding, 1798 (with subgenera Lampadopsis Jousseaume, 1881; Bufonariella Thiele, 1929 [= Dulcerana (Iredale, 1931, unavailable) Oyama, 1964 = Annaperenna Iredale, 1936 = Tritonoranella Oyama, 1964]; Colubrellina Fischer, 1884; Crossata Jousseaume, 1881 (with (?) subgenus Olequahia Stewart, 1926); Tutufa Jousseaume, 1881 (with subgenus Tutufella, new name for Lampas Schumacher, 1817, not of Montfort, 1808); Bufonaria Schumacher, 1817 [= Buffo Montfort, 1810, not of Lacèpède, 1788, = Marsupina Dall, 1904, =Chasmotheca Dall, 1904, = Bursina Oyama, 1964, = Gyrineum of authors, not of Link, 1807] (with subgenus Aspa H. and A. Adams, 1853); and Bechtelia Emerson and Hertlein, 1964.
The species and subspecies placed in Tutufa and its "subgenus" Tritonoranella Oyama, 1964 (shown to be a synonym of Bursa (Bufonariella) are classified as: Bursa (Bufonariella)) latitudo latitudo Garrard, 1961, Queensland; B. latitudo natalensis Coelho & Matthews, 1970, W. Atlantic; B. latitudo wolfei n.subsp., Hawaii; B. (Bufonariella) ranelloides ranelloides (Reeve, 1844), southern Japan; B. ranelloides tenuisculpta Dautzenburg and Fischer, 1906, E. & W. Atlantic to South Africa; B. ranelloides humilis n. subsp., Western Australia; Tutufa (Tutufa) bardeyi (Jousseaume, 1894), N. Indian Ocean; T. (Tutufa) bubo (Linneaus, 1758), Indo-West Pacific; T. (Tutufa) bufo (Röding, 1798), Indo-West Pacific; T. (Tutufella) rubeta (Linnaeus, 1758), Indo-West Pacific; T. (Tutufella n. subgen.) oyamai Habe, 1973, E. Indian Ocean and W. Pacific; T. (Tutufella?) tenuigranosa (E. A. Smith, 1914), South China Sea; and T. aff. rubeta, Mocambique. A neotype is designated for Murex rana var. bubo Linnaeus, 1758, and lectotypes are designated for several other species.
