Type locality. — America. 



Range. — From Rio Yaqui in southern Sonora (Camoa), southern 

 Durango (Guasamota), Morelos, southeastern Mexico (Chalco), and 

 the western boundary of Tamaulipas (Hidalgo), south through Mexico 

 and Central America to southern Peru (Urubamba Valley) and Pacific 

 coast of Argentina (Buenos Aires). These enormous toads either 

 were indigenous to or have been introduced on many of the Windward 

 Islands, including St. Kitts, Nevis, Antigua, Montserrat, Guadeloupe, 

 Paget (East Bermuda), Martinique, Santa Lucia, Barbados, and 

 Grenada. They occur also on Tobago and Trinidad, and have been 

 introduced into Jamaica and Porto Rico. In most places where they 

 have been introduced they have multiplied very rapidly. Reported 

 from: Sinaloa, Presidio de Mazatlan (Forror); Durango, Ventanas 

 (Forrer); Jalisco, north of Rio de Santiago (Godman), Guadalajara
