Thanks Alexei,

It's nice to get some photos of this species , which is certainly unfamilar to me. Your radular mount is almost identical to Baba's original drawing, but he describes the blade as 'non-denticulated'. I can only presume you have better optical equipment available than Baba did at that time. Another point of similarity is his description of the 'dark mottles' scattered over the body and cerata, and the rhinophores having a 'dark ring down the tip'.

Best wishes,
Bill Rudman
