The type species is the common raven ("Corvus corax"); others named in the same work include the carrion crow ("C. corone"), the hooded crow ("C. cornix"), the rook ("C. frugilegus"), and two species which have since been moved to other genera, the western jackdaw (now "Coloeus monedula") and the Eurasian magpie (now "Pica pica"). At least 42 extant species are now considered to be members of "Corvus", and at least 14 extinct species have been described.
