Cuthona punicea from British Columbia

From: Marli Wakeling

Hi Bill,
Here is Cuthona punicea. It was found at Eggmont, British Columbia [Canada] at 45 feet on a vertical wall, amongst Hermissenda
crassicornis.  Identification has been disputed between this species and Catriona columbiana.  The lack of orange pigmentation and the shape of the cerata lead me to believe it is the former.  This specimen was 15mm long.  I have also found much smaller creatures on egg masses, also on a vertical wall at the same depth at Orlabar Point, near Nanaimo, B.C.

Regards,

Dear Marli,
Thanks for the photo. Can you give me a reference for Cuthona punicea? I haven't had an exhaustive look, but I can't a reference to this species.

Your animal however, looks identical to the one Dave Behrens' (1980) identifies as Catriona columbiana in . I could search through the literature myself, but I have a backlog of about 80 messages at present, so if anyone can help me out by clarifying the identification problems between these two species I would be grateful.

Best wishes,
Bill Rudman.
