You have to prefix the environment with py27. So you would be running `tox -e py27-record`
Since no base Python version is defined in to, it probably uses the Python version that was used to install tox itself. 

You can have a look at the tox config. You could also specify the django version to be used by adding django110 to the command (the environment selectors are always separated using hyphens)
