Dear Dr. Rudman,
I would like to record this Cuthona pinnifera which was collected from under a stone. We use to observe this species frequently but recently it has been rare. I saw the page on the Forum for Cuthona cf. pinnifera so I have also included a scan of the original drawing that was used in Opisthobranchia of Toyama Bay and adjacent waters.
Collection data: 20 April 2002. Uozu, Toyama Bay. Alive 12mm length. Water temp: 12.3deg C.

Thanks for this information. It certainly clarifies the identity of this species.
