BUFO. BUFO AGUA (LAT.) TOAD.

[Illustration]

This toad is found all over America; it inhabits swamps and marshy

regions. It is as big as two fists, though its size varies a good deal.

It is readily known by its enormous rhomboïdal parotids, whence it sends

forth a large quantity of poison. Its head is flat, triangular, more

large than long; it shows a strong osseous edge, commencing at the tip of

the muzzle, thence stretching towards the inner angle of the eye, round

this organ, and finally terminating behind the lids. The eye and the

tympanic wall are very large. The trunk, which is very large anteriorly,

in consequence of the large development of the parotides, is covered,

on each side of the dorsal spine, with two irregular rows of large

elliptical or conical bladders; sometimes there are such bladders on the

sides. The anterior extremities do not reach to the end of the trunk; the

posterior extremities reach beyond the muzzle by the length of the fourth

toe. The toes are rather flattened; the first toe is longer than the

second. Its colors are various, consisting of a number of brown spots,

which coalesce on the back, and are separated on the abdomen by yellowish

dots.

The horrible croaking of these animals is well known, and might rouse the

indignation of the most phlegmatic individual.

By exciting the animal, we caused it to spirt its saliva, which we

collected on a little sugar of milk, and at once prepared, by trituration.
