Genus Cetorhinus Blainville, 1816

Basking Shark / Ǫḛé

Cetorhinus Blainville, 1816: 121 . Type species: not designated; Blainville included the species “ Gunneri; Peregrinus ; Shavianus; Homianus?” in Cetorhinus without further comment. Gill (1862) designated Squalus maximus “Linnaeus ” (= Gmelin, 1789) as type of Cetorhinus , but this was not an included species. Jordan & Gilbert (1883) designated “ Cetorhinus gunneri Blainv. = S. maximus L.” (a junior synonym of Squalus maximus Gunnerus, 1765 ) as type of Cetorhinus , which may be the earliest valid type designation. Eschmeyer (2012) cited Jordan & Evermann (1896) as a later, similar type designation.
