Seeking ID. Black hole? Black pearl?

[tangles_the_sparrow]

Good morning,

I have a master list of all my zoas and their names. However part of that list vanished. Including these guys. Their name i thought was something spacey like black hole. But it might have been black pearl? Really neat purple center and yellow skirt.
I bought them from some one here and for the life of me I cannot find that post.

Those look like black pearls.
