Dear Bill,
Concerning the mystery from Alaska.
At my website are some nice shots of  Pterotrachea coronata Forskål, 1775 - well, no OPISTHOBRANCHIA, but perhaps is the mystery of this pelagic kind.
Sorry, the text is only in German.
Have a look at: http://www.medslugs.de/D/PROSOBRANCHIA/Pterotrachea_coronata.htm

Thanks Erwin,
They are nice photos. I didn't realise it grew to 30cm in length.

To those who are not sure what Carinaria is, it is a pelagic snail which lives its life in the plankton, hunting and eating other pelagic animals [Superfamily Carinarioidea - often called Heteropoda].
