These would appear to be among the color forms of Goniobranchus preciosus, although the marginal coloration on several of them was a bit unusual. A typical G. preciosus would have a three-colored margin, white on the outside, then red, then yellow. In some of these specimens, the white portion had turned light blue and thickened to break up the middle red band into a series of spots.
A little difficult to see the white outer marginal line in this one, so it is possible it is a form of Goniobranchus verrieri.
With an egg mass.
In the photo below, you can distinguish the masses of orange extra-capsular yolk spread throughout the egg mass. Usually there is single small "cap" of yolk adjacent to each ovum.
