Dear Les,
From its general shape and colour I would guess this is a member of the Aeolidiidae, and is almost ceratinly one of the animals I have been calling Spurilla neapolitana from the tropical western Atlantic. There seem to be a couple of similar species confused on the page, one with double rows of cerata like yours, and one with more cerata. I can't say I am very confident that either are S. neapolitana. It is the animal Colin Redfern calls Spurilla sp. inBahamian Sea Shells . If you look at the inset of the magnified rhinophore you will see a brown network on the white. I am sure this is branches of the digestive gland ramifying inot the skin of the body wall, which is a sure sign of a solar powered species. Not that that identifies it, but its a nice bit of background information.

For convenience, I am keeping all these Caribbean animals together on the S. neapolitana page.

Best wishes,
Bill Rudman
