(Coraciidae; Ϯ European Roller C. garrulus) Gr. κορακιας korakias  type of crow or daw, perhaps a chough  < κοραξ korax, κορακος korakos  raven  < κρωζω krōzō  to croak; “A genus nearly related to the Crow. Thence Linnaeus calls it Coracias: A word of Aristotle’s applied only to what we call the Cornish chough” (Pennant 1773); the rollers were formerly included in the Corvidae next to the jays Garrulus and choughs; "49. CORACIAS.  Rostrum cultratum apice incurvato, basi pennis denudatum.  Lingua cartilaginea, bifida." (Linnaeus 1758); "Coracias Linné, Syst. Nat., ed. 10, 1, 1758, p. 107. Type, by subsequent designation, Coracias garrulus Linné. (Gray, Cat. Gen. Subgen. Bds., 1855, p. 131)  ...  1 In list Gen. Bds., 1840 and ed. 2, 1841, Gray designates Coracias abyssinica Gm. as type of the genus, a designation that is invalid since this was not one of the orignally included species." (Peters 1945, V, 241).  Linnaeus's Coracias comprised six species (C. Garrulus, C. caffra, C. Oriolus, C. Galbula, C. aurea, C. Xanthornus).   The European Roller has a distinctive, rolling or tumbling display flight from which it received its substantive English name.
