I've been searching for that one on and off since you last posted it
I have a correction to make to my comments above about neither Le Genie Verrier de L'Europe nor The Art of French Glass showing pieces with applied animals id'd as Auguste Jean - I failed to notice in Cappa page 285 that there is a leaning, completely clear tall vase with spiky and drip rim and rigaree trails as feet and that it also has an applied Lizard on it in clear (with ref the signature it says in the book traces of enamel on base)
