The southwestern terminus of the range of this species is on the Mexican
Plateau in Michoacan. All specimens from the state have spotted venters.
In living toads the dorsal ground color was gray or grayish tan with
olive green spots. The vocal sac was brownish gray; the iris was a
bright golden color.

On June 11, 1958, many individuals were calling from shallow water in a
flooded field at Emiliano Zapata. The call is a slow trill, in which the
individual notes are discernible.

This large toad is characteristically found in areas supporting tropical
scrub forest to elevations of about 1000 meters. The species is much
more abundant than the numbers listed above suggest. In the dry season
individuals have been observed in patios, along streams, and by
irrigation ditches. In the rainy season the loud, rattling call of the
males is heard at night throughout the Tepalcatepec Valley and the
coastal lowlands.

Taylor and Smith (1945:552) revived Wiegmann's _Bufo horribilis_ for the
large toads of Mexico that are here referred to _B. marinus_. Their
action was based upon the supposition that the "species _marinus_" is
composite. Although probably true, this supposition has yet to be
proved. Until the large, and apparently related, species of _Bufo_
inhabiting tropical America have been studied systematically as a unit,
the recognition of segments of the population as either species or
subspecies is meaningless. Taylor and Smith (op.
