Araucana or Ameraucana's? That is the question!

I stand corrected!  My two aren't Aracauna's as the lady told me and I just read on the chicken chicks site the difference with pictures.  She has the best description I've seen so far!  Mine are not what I thought and they are for sure Americana's as they don't have the tufts standing up from their faces, they do have the muffs of the Americana's though.
