DESCRIPTIVE LIST OF THE TOADS AND FROGS. 
The Common Toad, Bufo lentiginosus americanus Le Conte 
(Fig. 16), is of moderate size and stout form. The skin is very 
rough. A large and prominent gland exists behind 
the eye. Color above brownish or yellowish brown, 
with numerous large dark spots, narrowly, though 
distinctly, edged with pale yellow. Extending down the center 
of the back is a pale yellowish or whitish band. The abdomen 
is dirty white. The ground color varies in individuals, some 
being distinctly reddish, and is influenced by temperature and 
changes on the individual itself from a lighter to a darker shade 
or the reverse. The pupil of the eye is horizontal. 
The Toad is a familiar creature and is quite characteristic 
in appearance on account of its very rough glandular skin and 
the large, swollen glands behind the eyes. The hind feet are 
but slightly webbed. The blackish hue of the skin under the 
throat of the male Toad distinguishes it from the female. This 
skin is capable of great extension as the creature gives voice to 
the peculiar cry of the breeding season. The females are larger 
than the males. Length of body of male specimen, 2% inches; 
of female, 2? inches.
