In earlier messages I wondered about the differences between Cuthona punicea and Catriona columbiana

In Dave Behren's (1991) Pacific Coast Nudibranchs 2nd Edition there are photos of both. Both species have similar distributions and look quite similar. One fairly distinctive colour difference is that in Cuthona punicea the oral tentacles are translucent with a white line down the dorsal surface while in Catriona columbiana they are orange with white tips.
