Is this really a percivaliana coerulea undine? I suppose perhaps its a percivaliana, something doesnt look quite right to me, but moreover it definitely doesnt look like the undine/ondine photos I've seen!
I kept scrolling past page after page of photos and did find some with the more open lip showing the column. We're accustomed to seeing percivaliana with a tightly rolled lip. I agree Waldor is unlikely to sell something misidentified.
