Birds, p. 76) and under plenary powers of the International Commission on Zoological Nomenclature, 1956, Opin. Decl. Rend., 13, p. 4, Colymbus cristatus Linnaeus." (Storer in Peters 1979, 1, 2nd. ed., 148). The legs of the Great Crested Grebe are set back to the rear of the body, giving rise to a former name “Arsefoot” which may have influenced Latham's coinage.
