Concerning message #17145:
Bill and Willfried,
I suggest you consider Calma glaucoides as the ID for this specimen. It has a variable appearance but the cerata clusters are arranged distinctively and argue against a cuthonid. I attach a photo of a well fed, large UK specimen but Bernard Picton's website shows a less superficially pigmented form.
Locality: Penzance, 15m, Cornwall, Atlantic UK, August 1977, unknown. Length: 23 mm. Photographer: finder unrecorded, photo Greg Brown.

Thanks for the suggestion. Looking at Gonçalo Calado's photo [message #8267] of a juvenile Calma glaucoides, I can see the same ceratal arrangement and triangular oesophageal-stomach region. I guess I expect C. glaucoides to have the characteristic 'bunches of grapes' white gonad down each side of the dorsal midline, but the gonad is not really visible in juveniles.
