Hi Bill,
I would suggest that Marli have someone look at the internal anatomy of this species. Cuthona columbiana has orange rhinophores and oral tentacles. Also the white stripe up each ceras is usually unbroken. Marli's animals look externally like light colored specimens of Sandra Millen's Cuthona punicea. C. punicea has a white line on the oral tentacles and white specks over the cerata.

From Sandra Millen's earlier comments I had assumed these animals with a broken white line were also C. columbiana. They have orange on the rhinophores which Sandra says does not occur in C. punicea, but I agree, in the end the anatomy will need to be checked. By chance I am also posting today some photos which Marli has identified as C. punicea. Would you agree with that identification?
Cheers,
Bill Rudman
