DEFINITIONS

CORVUS
(Corvidae; Ϯ Common Raven C. corax) L. corvus  raven. In fable the Raven was originally white but, despite its supposed gift of prophecy, was turned into a black bird for its treachery. The Common or Northern Raven is the largest species of passerine bird; "48. CORVUS.  Rostrum convexum, cultratum, basi pennis setaceis tectum.  Lingua cartilaginea bifida." (Linnaeus 1758); "Corvus Linnaeus, 1758, Syst. Nat., ed. 10, 1, p. 105. Type, by tautonymy, "Corvus", i.e. Corvus corax Linnaeus." (Blake & Vaurie in Peters, 1962, XV, p. 261).  This is the ninth diagnosed genus in avian taxonomy.  Linnaeus's Corvus comprised twelve species (C. Corax, C. Corone, C. frugilegus, C. Cornix, C. Monedula, C. benghalensis, C. glandarius, C. cristatus, C. Caryocatactes, C. Pica, C. paradisi, C. infaustus).

• "There is just one Mexican bird to which the description of the Hocitzanatl can apply and that is the Great-tailed Grackle, at present known as Megaquiscalus major macrourus, and having so identified Corvus mexicanus a far reaching trail of consequences arises.  ...  This action is three-fold in its immediate effect on nomenclature, for in the first place the Rice Grackles will require a different generic name, furthermore the bird hitherto known as Cassidix oryzivora mexicana (Less.) must be renamed  ...  and lastly the mexican Crow must receive a name, since it never really had one.  ...  This leaves but one more change to make, that of naming the Mexican Crow.  It may be called:  Corvus imparatus, sp. nov." (J. Peters 1929) (Corvus).
