. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. Chamaeleonid nomenclature 33 The combination of characters given in the original description allows to assume that neither a Madagascan nor a mainland African species is concerned. Thanks to the recovery of the holotype (ZSI 6839, snout-vent length of mm, a tail length of mm, a head width of mm: Fig. 1) by the second author, it became possible to support this assumption and to verify the identity of Blyth's name. It actually refers to the only chamaeleonid species inhabiting Socotra Island (Republic of Yemen, although originally believed to be Madagascan by Gray [1865: 470], the endemic Chamaeleo monachus Gray, 1865 based on the specimen BM (Fig. 2)] (cf. Klaver & Böhme 1997: 35). Fortunately, this does not constitute any nomenclatural threat to C. monachus Gray, 1865: Chamaeleon verrucosus Blyth, 1853 is a junior primary homonym of Chamaeleo verrucosus Cuvier, 1829 which refers to a Madagascan species now iQvmQá Furcifer verrucosus (Cuvier, 1829) (see Klaver & Böhme 1986: 59, 1997: 21). Accordingly, Blyth's name of 1853 is invalid and consequently, there is no need to replace the junior homonym of C. verrucosus Cuvier, 1829 by a nomen novum. The latter name has been in extensive use since its first erection, Boettger (1877: 39), Blanford (1881: 464), Boulenger (1887: 451, 1903: 87), Mocquard (1893: 6, 1894: 114), Werner (1902: 344, 1911: 14), Steindachner (1903: 14), Hillenius (1959: 52), Mertens (1966: 20), Klaver (1977: 184, 1981: 43), Klaver & Böhme (1986: 59, 1997: 35), and Showier (1994: 10, 1996: 185)..
