Dear Don;- If it looks like a duck and quacks like a duck, it's probably a duck. The same goes for E. lamellosum, a world wide species. Now the other one is interesting. When your dive buddy goes and gets a couple more, send one. I don't know of S. pernobilis being from those parts, as it inhabits similar depths but from North Carolina to the Antilles. If your dive buddy doesn't find anymore, try to get a decent photo done. Art
