Anaxyrus fowleri (Hinckley, 1882)
Bufo lentiginosus var. fowlerii —Putnam In Cope, 1875, Bull. U.S. Natl. Mus., 1: 29. Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 310. Nomen nudum.
Bufo fowleri Hinckley, 1882, Proc. Boston Soc. Nat. Hist., 21: 310. Syntypes: Not stated, including MCZ 518 (4 specimens), according to Barbour and Loveridge, 1929, Bull. Mus. Comp. Zool., 69: 231. Peters, 1952, Occas. Pap. Mus. Zool. Univ. Michigan, 539: 11, regarded UMMZ 50246 as a "cotype" of Bufo lentiginosus fowleri Garman, 1884, rendering the status of this specimen arguable. Kluge, 1983, Misc. Publ. Mus. Zool. Univ. Michigan, 166: 24, noted that none of the MCZ specimens considered previously to be syntypes of Bufo fowleri were actually seen by Hinckley, and he therefore designated UMMZ 50246, as neotype after discussion of the confusion surrounding the authorship of the name. Type locality: "Milton, [Norfolk County,] Mass[achusetts].", USA. Neotype from "United States: Massachusetts: Danverse". See comments by Myers, 1931, Copeia, 1931: 94-96, regarding the description.

Type locality: "Elkhart, Anderson County, Texas", USA. Status controversial, may have originated through hybridization with Bufo woodhousii, according to Sullivan, Malmos, and Given, 1996, Copeia, 1996: 274-280, who also noted that this taxon may belong in the synonymy of Bufo woodhousii, or formed through ancient hybridization with Bufo terrestris (according to Volpe, 1959, Am. Midl. Nat., 61: 295-312). See comments under Anaxyrus fowleri and Anaxyrus woodhousii.

Distribution

Comment
In the Bufo americanus group according to Blair, 1959, Texas J. Sci., 11: 427. The status of Anaxyrus fowleri as distinct from Anaxyrus woodhousii was formerly controversial although at the time of this writing (2002) seems to be generally accepted. See Green, 1996, Israel J. Zool., 42: 95-109, and Sullivan, Malmos, and Given, 1996, Copeia, 1996: 274-280, for discussion of the issue (and Meacham, 1962, Am. Midl. Nat., 67: 282-304, for a presentation of evidence) and delimitation of the species. Green, 1996, Israel J. Zool., 42: 95-109, provided a lucid discussion of the problem of interspecific hybridization in the Anaxyrus americanus complex and briefly addressed the unfortunate publication by Sanders, 1987, Evol. Hybrid. Spec. N. Am. Indigenous Bufonids, in which Sanders recognized a number of dubiously delimited taxa within the Anayxrus americanus complex (Bufo hobarti which is now in the synonymy of Anayxrus fowleri; Bufo velatus, which now either in the synonymy of Anayxrus woodhousii or Anayxrus fowleri; Bufo copei, which is in the synonymy of Anayxrus americanus, and Bufo planiorum and Bufo antecessor, both of which are in the synonymy of Anayxrus woodhousii woodhousii). None of these names have been formally synonymized as part of any revisionary activity, but neither have they attracted any recognition by those working on the complex (DRF). Most recently Masta, Sullivan, Lamb, and Routman, 2002, Mol. Phylogenet. Evol., 24: 302-314, on the basis of molecular evidence suggested that Anayxrus fowleri is most closely related to (and molecularly paraphyletic with respect to) Anayxrus terrestris, not the closest relative of Anayxrus woodhousii, and together with Anayxrus terrestris forming the sister taxon of Anayxrus americanus plus Anayxrus woodhousii. According to these authors Anayxrus fowleri is composed of three molecularly distinctive populations, which require additional study as to their taxonomic status. Barker and Caduto, 1984, Herpetol. Rev., 15: 52-52, provided a record for Vermont. Fontenot, Makowsky, and Chippindale, 2011, Mol. Phylogenet. Evol., 59: 66-80, discussed hybridization with other members of the Anaxyrus americanus group.
