Hmm. Comparing the Ancient Dragon from Dark Souls 2 along with the ones we find in Dark Souls 1, I have come up with a theory that coincides with this discussion.

Whenever the Everlasting Dragons were refered to, it typically showed or refered to the Dragons that sat upright, had 2 sets of wings, and a set of arms instead of legs (i.e. Seath, the Stone Dragon, and possibly the Gaping Dragon). Meanwhile, there are other dragons that stand on four legs, no arms, and have only one set of wings. I believe that Seath and the Stone Dragon are both from the Everlasting Dragon gene pool, while Kalameet, the Ancient Dragon, and all the other Dragons we find at Dragon Aerie to be part of the second family, aka the Ancient Dragons.
