Unfortunately, I do not have photos or any other data to share, but if I see it again I will let you know. Dear Chad, Thanks for the information. I think your reply arrived within 15 minutes of me posting Cynthia's message . Best wishes, Bill Rudman. Yet another query that has long puzzled me.
Most species have just one per capsule.
The latter is particularly troubling to me, particularly after reading an account for S. fuscovittatus that cases with 2 ova per capsule do not develop. Some of the variation is within individual egg masses. I thought I had some, but perhaps I did not. I did most of my looking at egg masses at Enewetak in the early 80s, and the way I collected eggs for examination, in plastic tubs floating in flow-through sea tables, did not really lend itself to my low tech, Nikonos extension tube photography. I'll try to get some more and do a better job.
