Bufo marinus : I collected by Sam Sweet
on a spit of mud extending out into the lake. Has

Bufo valliceps : I caught one, and
Sam caught one. Jim Hunter caught two.
The specimen I caught was near the water.

Rana berlandieri : I caught 6, Sam
caught 12 and Jim Hanker got 2. Most
of these were either in the water or at the

Only a couple of really large frogs were seen
and Jim caught one of these.

Natrix rhombifera : I caught one
large one and Sam caught a second. I missed
a smaller specimen. All three animals
were hunting in the shallows at the west end of
