RYAN2691, the information I have come across has been from a variety of sources. I find the more ways you type in Hountain Horned Dragon on google the more results you will find. (Whan I say "more ways" I mean type in, Acanthosaura, Mountain horned agamids, A.armata etc., and pricklenape lizard, as well as any other names you are able to find). These lizards are one of the most varaibly named reptiles I have ever come across so the possibilities are almost endless. Hope this helps you in your research.
