Bill:

The crayfish came from Hartley's via Rex. Hartley's nor Mr. Lusk knew the species. Hartley's called it a "Green crayfish". The pic of the crawdad is in the first post, and they look exactly like the crayfish that are in the local lake. I took them out of the container and stocked them into the pond one at a time, and they all looked the same other than the immature ones, which look exactly like the immature ones in the local lake as well.

Do you know of any place on the internet that I can look to try to identify them?

You are absolutely correct, take Rusty crayfish for instance!
