Cassidix
• (Icteridae; syn. Quiscalus † Great-tailed Grackle Q. mexicanus) L. cassis, cassidis  metal helmet; "CLXXVII.e Genre. CASSIDE; Cassidix.  Bec un peu plus long que la tête, très-épais, robuste, quadrilatère, conique, peu comprimé sur les côtés; arête dilatée, disposée en plateau ovalaire, entamant les plumes du front, régnant sur toute la longueur du bec; narines ouvertes, arrondies, percées sur les côtés et en dessous du plateau; commissure très-déjetée; branches de la mandibule inférieure renflées, tarses alongées, très-forts; queue ample, deltoïdale, échancrée, ailes alongées, pointues, à première rémige très-longue.   CASSIQUE A MANTELET; Corvus mexicanus, Gm. De Cayenne (M. Martin); Cassicus niger, Vieill., Gal., pl. 89?" (Lesson 1831); "Cassidix Lesson, Traité d'Orn., p. 433, 1831—type, by monotypy, Corvus mexicanus Gmelin. 1 ...   1As pointed out by Peters (Proc. Biol. Soc. Wash., 42, p. 122, 1929), it seems hardly avoidable under present rules to use the generic name Cassidix for the group of birds known as Megaquiscalus.  Although the generic characters were clearly taken from the Rice Grackle (Oriolus oryzivorus Gmelin), of which Lesson had seen specimens from "Cayenne (M. Martin)," his citing of Corvus mexicanus Gmelin as the only species (Cassicus niger Vieillot is merely given as a doubtful synonym, and not as a second species) appears to fix the genotype in an unequivocal sense." (Hellmayr, 1937, Cat. Birds Americas, Pt. X, p. 88); "Cassidix Lesson, 1831, Traité Ornith., p. 433.  Type, by subsequent designation (G. R. Gray, 1840, List Genera Birds, ed. 1, p. 41), Cassidix mexicanus Lesson = Corvus mexicanus Gmelin." (Blake in Peters, 1968, XIV, p. 187).
