The first few photos show an individual that was observed on the slope just east of the Liberty shipwreck at Tulamben. It is similar in size and shape to Hypselodoris tryoni, but differs in having more reddish colored spots over a more lavender cloudy background. It is likely just a color variant.
The next three photos are puzzling. The animal on the left of the first photo looks very much like typical Goniobranchus leopardus. The one on the right with the reddish spots looks like the species we have been calling Hypselodoris cf tryoni (which is probably just a color variant of H. tryoni). Yet the two are clearly mating. Either they are a bit confused or they are actually odd color forms of a single species, possibly H. tryoni.
