Here is another specimen I'm not sure of. This one is a pleurobranch that was photographed in the Red Sea at 'Nurses' dive site (near Amq, about 400km south of Jeddah) on December 17th, 1992.
The specimen measured 30mm in length and was found at night on the reef flat at a depth of 1.5m. The notum consists of low tubercles and has a mottled brown pattern. When I first looked at the slides I thought the specimen had white filamentous processes on the notum but close observation reveals that these are simply triangular white patches on the sides of some of the tubercles. I have attached a close up image of a portion of the notum showing these white spots.
Could this be a form of Pleurobranchus albiguttatus?

It certainly looks like Pleurobranchus albiguttatus. The tricky white traingular marks are certainly a hallmark of this species.
