Schwalbe, in a lecture delivered during a meeting of the Society of German Naturalists and Physicians, held at Cassel in 1903, and subsequently published in 1904, proposed the name Homo primigenius with the Neanderthal 1 specimen as the holotype. Both Campbell (1965 p. 22) and Groves (1989 p. 288) list this taxon as an objective junior synonym of Homo neanderthalensis King, 1864. It is also a primary junior homonym to Homo javanensis primigenius Houzé, 1896. Thus, the name is available but objectively invalid.
