Montandon has Homo sapiens proto-sapiens as the subtitle for chapter IX of his 1943 book. In this chapter Mantondon describes Piltdown and Swanscombe A and B. Swanscombe C was not yet discovered. Campbell (1965) listed the name as valid and fixed Swanscombe as the lectotype. Groves (1989) listed this taxon as available and potentially valid provided the name is corrected to remove the hyphen (Article 32.5.2.3).
