Yippee, I have the second set of the rules and it does indeed have a lion and a retiarius, not to mention a  venator/bestiarius an amazon and a poor condemned slave.

Once again a big thank you to EM4 who gave me access to the Yahoo group and allowed me to download the LGII. 

The retiarius type will be useful for my Laquearius types armed with a lasso and a whip.

My Ludus will now be able to field a wider range of types than before.
