Nassarius or Trochus eggs?

[ASIN28]

Hey all,
What does this look like to you? Nassarius snail eggs or Trochus snail eggs? And what is the next step or stage after this on the glass?
Thanks

Do you have Tonga Nassarius? They are the larger ones? Their eggs go back and forth like these. I clean them off my glass. Or not. Wish they would survive.
