Are these Cerith snail eggs?

[Euphylliaphyle]

I have Ceriths, Nassarius (but these don't look like images I have seen), Astreas (but those are broadcast spawners) a single Zebra Turbo (but I don't think it can squeeze into this space), Marginellas (I don't think this mass of eggs can fit into one of their tiny bodies) and Vermetids (but they're sessile, and tiny).
Also, there was a Cerith in the vicinity this morning, so Occam's Razor suggests these are from a Cerith.
Can anyone confirm?

Yeah, Cerith snails; Marginella snails (at least some species) lay larger eggs (~1/4 the size of the adult shell) individually, not in strings. For example:
