All a matter if you keep going out and recording you find things.

We took our lumps, these had been sitting in their critter keepers
outside in the shade. They were fully primed.

Maybe on the small size, but close. And about the same size as the
regulars from there. If anything they give the impression of being just
slightly squeezed shorter, making them look slightly plumper. But that's
very slight. I did not actually try to take a ruler to them.

Actually Justin's fingers. He got wrangling duties while I tried to keep
up with the camera.

 From what I've seen in photos of olivacea, I concur. I've also heard
the call, it's online, and it's not right though a little closer:
http://www.zo.utexas.edu/research/txherps/frogs/gastrophryne.olivacea.html
http://www.zo.utexas.edu/research/txherps/frogs/calls.html
(and now everyone knows where I got the initial layout ideas for my frog
pages, many years ago)

There could be something along that line, as these have less belly
spotting. I should suggest that their genetics be compared to olivacea
as well if possible.
