than those
that are limiting to it or even typical of it.

On September 20, 1954, after heavy rains, juveniles dispersing from
breeding ponds were in a wide variety of situations, including most of
the habitat types represented on the Reservation. Along a small dry
gully in an eroded field formerly cultivated, and reverted to tall
grass prairie (big bluestem, little bluestem, switch grass, Indian
grass), the frogs were numerous. Many of them were flushed by my
footsteps from cracks in the soil along the gully banks. In reaching
this area the frogs had moved up a wooded slope from the pond, crossed
the limestone outcrop area at the hilltop edge, and wandered away from
the woods and rocks, out into the prairie habitat. In this prairie
habitat there were no rocks providing hiding places at the soil surface,
but burrows of the vole (_Microtus ochrogaster_) and other small rodents
provided an abundance of subterranean shelter. In the summer of 1955 the
frogs were seen frequently in this same area, especially when the soil
was wet from recent rain. When the surface of the soil was dry, none
could be found and presumably all stayed in deep cracks and burrows.

Anderson (1954: 17) indicated that _G. carolinensis_ in Louisiana
likewise occurs in diverse habitats, being sufficiently adaptable to
satisfy its basic requirements in various ways.

BEHAVIOR

Ordinarily the ant-eating frog stays beneath the soil surface, in cracks
or holes or beneath rocks. Probably it obtains its food in such
situations, and rarely wanders on the surface. The occasional
individuals found moving about above ground are in most instances
flushed from their shelters by the vibrations of the observer's
footsteps. On numerous occasions I have noticed individuals, startled by
nearby footfalls, dart from cracks or under rocks and scuttle away in
search of other shelter. Such behavior suggests that digging predators
may be important natural enemies. The gait is a combination of running
and short hops that are usually only an inch or two in length. The flat
pointed head seems to be in contact with the ground or very near to it
as the animal moves about rapidly and erratically. The frog has a
proclivity for squeezing into holes and cracks, or beneath objects on
the ground. The burst of activity by one that is startled lasts for only
a few seconds. Then the frog stops abruptly, usually concealed wholly or
in part by some object. Having stopped it tends to r
