Rana boylii Baird, 1854, Proc. Acad. Nat. Sci. Philadelphia, 7: 62. Syntypes: Not stated; USNM 3370 (2 specimens) according to Cochran, 1961, Bull. U.S. Natl. Mus., 220: 72. Type locality: "California (interior)"; corrected to El Dorado, California [USA] by Cope, 1889, Bull. U.S. Natl. Mus., 34: 447; syntypes from El Dorado County, California, USA, according to Cochran, 1961, Bull. U.S. Natl. Mus., 220: 72.

Comment

See Zweifel, 1955, Univ. California Publ. Zool., 54: 207-292, and Zweifel, 1968, Cat. Am. Amph. Rept., 71: 1-2, for review. In the Rana boylii group of North American authors. In the Rana aurora group of Dubois, 1987 "1986", Alytes, 5: 42, in the equivalent Section Amerana, subgenus Amerana of Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 322. (Although Amerana was shown by Hillis and Wilcox, 2005, Mol. Phylogenet. Evol., 34: 305, to be polyphyletic.) Grismer, 2002, Amph. Rept. Baja California: 82, discussed the Baja California, Mexico, record. Stebbins, 2003, Field Guide W. Rept. Amph., Ed. 3: 231-232, provided a brief account, figure, and map (and who commented on the disappearance of this species from large areas of its former distribution). See statement of geographic range, habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 631. Fellers, 2005, in Lannoo (ed.), Amph. Declines: 534–536, and Dodd, 2013, Frogs U.S. and Canada, 2 : 697–707, provided accounts that summarized relevant literature. Elliot, Gerhardt, and Davidson, 2009, Frogs and Toads of N. Am.: 248–249, provided an account, photos, and advertisement call. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 242–243, provided an account of larval morphology and biology.
